The river temperature was pretty much the same as the spring temperature at 71.9°F (22.2°C). I counted 7 manatees, none of which were adoptees and they were all hanging out in the canoe basin by the river.  We didn’t do any counts yesterday and Wednesday, but adoptee Annie made a quick visit on Wednesday and was seen on the webcam.

The river temp was 72.1°F (22.3°C). Just a tiny bit lower than the spring run. We saw 12 manatees and none were Save the Manatee Club adoptees. However, Cora found Alligator on the webcam Saturday, March 23. I suppose he did an in and out to see who might be at the spring.

La température de la rivière était légèrement plus fraîche que celle du printemps, soit 70,5°F. J'ai compté un nombre surprenant de 21 lamantins ; beaucoup d'entre eux sont des lâchers récents, mais j'ai aussi vu un couple mère-petit et un groupe de mâles. Cela m'a fait me demander si les mâles pouvaient provenir d'un troupeau d'accouplement en dissolution, ce qui n'est pas rare au printemps et en été lorsque plusieurs mâles poursuivent une femelle en œstrus (chaleur) en grand groupe. Les mâles se reposaient tous ensemble en groupe près de la rivière.

Nous avons également commenté le tarpon. Aujourd'hui, ils étaient de nouveau en ébullition !

~Cora

Thursday, March 21, 2024

The river temp was 71.8°F (22.1°C) colder than the run, but it only produced 13 manatees for the count. None were Save the Manatee Club adoptees. The majority were still recent releases and juveniles coming in out of habit. The cold has gotten some of the tarpon back. They congregate at about the halfway point to the boil in the run. The temperature today is predicted to be 79°F so I do not expect many manatees tomorrow. The weather forecast is 90% chance of rain and high winds, so we might not be able to count.

La température de la rivière était de 72,7°F (22,6°C). Juste au-dessus de la température de fonctionnement. Nous avons compté trois lamantins et deux sont arrivés lorsque nous avons fini. Aucun n’était un adopté du Save the Manatee Club. Tous les lamantins d'aujourd'hui étaient des lâchers récents et j'ai l'impression qu'ils viennent plus par habitude que par besoin d'eau de source. Nous verrons ce que demain nous réserve avec les températures plus froides ce soir.

Tuesday, March 19, 2024

La température de la rivière aujourd’hui était de 75,2°F (24°C) tôt le matin. À midi, la température était tombée à 74,3°F (23,5°C) et l'air était nettement plus froid ce matin. En raison d'un autre engagement, j'ai dû faire le décompte plus tôt, j'ai donc commencé à 7h30 et je n'ai vu aucun lamantin. Le parc n'en a pas vu non plus, mais le personnel du parc en a vu arriver peu après 8 heures du matin. Peut-être que demain certains seront en fuite lors du décompte ! Il est censé rester frais jusqu'à jeudi, puis ce sera à nouveau l'été !

The river is back up to 75°F (23.9°C), and only one manatee was in the spring run. We are expecting a little cool front starting tomorrow until Thursday, so we shall see if that brings any manatees in. With the river so warm right now, they may not be coming back to the spring. Even all the tarpon seem to have left!

La température de la rivière était de 72,3°F (22,4°C). Donc deux jours avec la température de la rivière un peu en dessous de la température de ruissellement m'ont laissé un lamantin à compter. Ces températures d'automne en auraient rapporté, mais après un hiver très froid, les lamantins ne sont pas impressionnés. Le lamantin n’était pas un adopté du Save the Manatee Club. Je pense que je déciderai bientôt que la fin de la saison était il y a une semaine ou plus. Les lamantins qui arrivent maintenant le font par habitude, pas pour se réchauffer.

The river temperature this morning was 72.1°F (22.3°C), so a very slight drop from yesterday, but not significant. I counted 3 manatees—2 of them by the river and one up closer to the spring head. After the count was over, 2 more manatees were close to the river. One of them was “Irma,” a manatee released at Blue Spring a few years ago by the Manatee Rescue and Rehabilitation Partnership. It is always nice to see them return. Irma is hard to identify, so it’s always nice to see her. None of the manatees seen today were Save the Manatee Club adoptees.

Yesterday, the tarpon had returned to the boil for the day, for only the second time this season, when usually they are always found at the boil!

~Cora

Tuesday, March 12, 2024

The little cool spell lasted another night and the river dropped down to 72.6°F (22.6°C), which was quite a bit, but not enough to really make a big difference for manatees as it is still warmer than the spring run. I counted 8 manatees, most of them close to the buoy line where the river meets the spring run. 2 more came in after the official count was over. None were adoptees. Now it is predicted to warm up again!

Monday, March 11, 2024

Avec une petite vague de fraîcheur, la température de l'air est tombée à 50°F, mais la température de l'eau de la rivière Saint-Jean était toujours à 76,1°F (24,5°C), donc un peu plus chaude qu'au printemps. J'ai compté 3 lamantins lors de la migration printanière ce matin, dont aucun n'était adopté. Peut-être que quelques autres passeront demain avant qu'il ne recommence à se réchauffer. En plus du canard de Barbarie, un poisson gar albinos était au printemps aujourd'hui !

Friday, March 8, 2024

Beautiful day. Little wind, clear water, pleasant temperatures, no manatees. Actually, we had two manatees; one near the boil and one about 50 yards into the run. The river temp was 73.4°F (23°C) warmer than yesterday. The tarpon are leaving the run but the mullet are starting to come in. The mullet usually start in as the river warms up.

-Wayne

Thursday, March 7, 2024

Magnifique journée. Peu de vent, eau claire, températures agréables, pas de lamantins. En fait, nous avions deux lamantins ; un près de l'ébullition et un à environ 50 mètres du début de la course. La température de la rivière était de 73,4°F (23°C), plus chaude qu'hier. Les tarpons quittent la course, mais les mulets commencent à rentrer. Les mulets commencent généralement à entrer lorsque la rivière se réchauffe.

~Cora

Thursday, March 7, 2024

La température de la rivière est maintenant à 73°F (22,8°C), donc plus chaude que la crue printanière. Il n'est pas surprenant que le décompte soit resté à peu près le même qu'hier : 2 lamantins, un près de la rivière et un au printemps. Une fois le décompte officiel terminé, 4 autres lamantins sont arrivés, l'un d'eux étant un couple maman-petit (Moore et son petit) poursuivi par « Buckeye ». Buckeye est sorti chez Blue Spring il y a quelques années et semble très bien se porter. On peut souvent l'observer en train de chasser des lamantins femelles !

De plus, pour la première fois, j'ai vu un canard de Barbarie lors de la montaison printanière. C’était surprenant et probablement pas une bonne chose. 

Il semble que lundi et mardi prochains, les températures baisseront un peu, donc quelques lamantins pourraient revenir, mais avec la rivière si chaude, nous ne nous attendons pas à grand-chose.

The river temp was 72.5°F (22.5°C). The exact temp of the spring run. The dark river water was covering a third of the mouth of the spring run on the surface. I counted three manatees and the park counted one manatee. We both easily saw one about ten feet into the run, and I saw an additional manatee come up out of the dark river water to breathe next to him. I eventually found one more near the spring head. The weather was predicted to be a 50% chance of rain and high winds. I came out anyway, and the day was beautiful, although the wind was a little rough to be canoeing.

Tuesday, March 5, 2024

La température de la rivière avait atteint 71,6°F (22°C), elle est donc plus ou moins la même que la température printanière actuelle. Nous notons également toujours où se trouve la ligne d’eau sombre (l’eau de rivière intrusive). Souvent, le deuxième oubli est dépassé. Aujourd'hui, c'était presque au niveau de la ligne de bouées séparant la rivière de la ruée printanière, ce qui parle de lui-même : il se réchauffe et les lamantins s'éloignent !

Le parc comptait 2 lamantins et j'ai compté les mêmes 2 lamantins. L’un était un petit juvénile se dirigeant vers la rivière et l’autre était un lamantin récemment relâché. Un autre est passé après le décompte officiel. J'ai vu la grosse tortue serpentine résidente - nous la voyons plusieurs fois par saison, mais aujourd'hui, l'eau était belle, calme et peu profonde, il était donc facile de voir et de prendre des photos de la créature préhistorique !

Monday, March 4, 2024

The weather over the weekend was very warm, with highs in the upper 70s and even reaching the 80s and lows in the 60s. The river temperature rose to 70.3°F (21.3°C) this morning. The park saw one manatee during their count, who was headed towards the river. I counted no manatees, but saw 5-6 coming in and out after the count close to the buoy line by the river. None were Save the Manatee Club adoptees.

~Cora

Friday, March 1, 2024

La température de la rivière atteignait 19,4°C, mais j'ai compté 38 lamantins, ce qui était surprenant. Compte tenu de la température plus élevée et du décompte de 26 hier, je ne m'attendais pas à plus de 15. La plupart d'entre eux étaient juste au bord de la rivière pendant la descente de printemps, prenant probablement juste un peu de repos avant de repartir. Aucun n’était un adopté du Save the Manatee Club.

~Cora

Thursday, February 29, 2024

La température de la rivière était de 66,9°F (19,4°C). Nous avons compté 25 lamantins. Aucun n’était un adopté du Save the Manatee Club. Nous avons vu une carpe herbivore albinos. Les carpes herbivores sont exotiques et nous souhaitons qu'elles disparaissent.

Wayne & Cora

Wednesday, February 28, 2024

The river temp was up to 65.7°F (18.7°C). In November, the manatees would consider that cold but they seem inured to it now. We counted 53 manatees, but only 19 were adults. The young need the warm water most. No Save the Manatee Club adoptees were present. The tarpon that finally made it to the boil yesterday were gone. I guess one day was enough for them. It does not look too hopeful for manatee viewing for the next week. The season may be ending.

Wayne & Cora

Tuesday, February 27, 2024

The river temp was 64°F (17.8°C). We counted 162 manatees and one alligator. The season appears to be ending. The tarpon that I mentioned as stopping half way up the run reached three quarters yesterday and today there was a whole herd in the boil. I wonder why they waited so long?

Wayne & Cora

Monday, February 26, 2024

The river temp was 63.5°F (17.5°C). We counted 224 manatees, among them Save the Manatee Club adoptees Aqua, Alligator, Lénny, Phyllis, Annie, et Margarito. As we went, we watched for three manatees that need assistance, but not one of the three showed up. Perhaps tomorrow or some other day.

Wayne & Cora

Sunday, February 25, 2024

The river was almost the same as on Saturday, just slightly warmer at 63.3°F (17.4°C), and 273 manatees were counted. The adoptees in were Alligator, Annie, Aqua, Paddy Doyle, Brutus, Lénny, Una, Margarito, et Doc.

~Cora

Saturday, February 24, 2024

The river temperature was 63.1°F (17.3°C) and the count dropped down to 258 manatees. Most of them were by the river eager to go out to feed today while it was warming up. The adoptees seen were Annie, Una, Alligator, Doc, Lénny, Margarito, pseudo, et Aqua.

~Cora

Friday, February 23, 2024

The river was 62.4°F (16.9°C). That is cold but some warmer air temps are on the way. We counted 438 manatees, but I am sure it was an overcount due to high winds. The park counted 376 manatees. We could only ID Save the Manatee Club adoptees Howie, Brutus, Paddy Doyle, Alligator, Annie, Doc, et Aqua. I might have felt it was a bad day to go out, but we also saw an orphan we are keeping an eye on and got another film clip of a manatee and an alligator co-existing. They were napping, manatee nose to alligator tail.

Thursday, February 22, 2024

The river temp was down to 62.4°F (16.9°C). The manatee count should have gone up but it went down. I think they know it is going to get a little warmer the next few days. We counted 609 manatees and ID’d Save the Manatee Club adoptees HowiePaddy Doyle, Brutus, pseudo, Philippe, Dent profonde, Lis, Alligator, Lénny, Margarito, Annie, Una, Phyllis, Moustaches, Moo Shoo, et Doc. We have a second alligator sighted this season. An eight footer has been in the last three days. That is far more normal than none. Now if the tarpon would start using the top half of the run instead of just the lower. Manatees and tarpon in the boil make for nice pictures!

The river temp was 64.2°F (17.9°C). The mist was coming off the run very thick. Because of this, the count, which is always a bit of an estimate, was more of an estimate today. Manatees were thickest near the river but were wall to wall in several other parts of the run. We even had quite a few in the boil. The wind was very still and the run clear once we got away from the area near the river. As a result, we ID’d an enormous number of manatees. At least 279 out of 668 manatees. The Save the Manatee Club adoptees were pseudo, Paddy Doyle, Howie, Lis, Philippe, Floyd, Alligator, Phyllis, Moustaches, Moo Shoo, Dent profonde, et Brutus. Brutus was seen by Cora after the count from the boardwalk as she looked for some friends. The week ahead looks good for manatee viewing!

It was very rainy all weekend and the rain continued into the morning but finally let up.

The river temperature from the gauge in Deland (where we can look it up online) said 65.8°F (18.8°C) at 8 a.m. At 1 p.m., it had dropped to 63.5°F (17.5°C). Either something is wrong with the gauge, or the river really quickly dropped. Regardless, park staff counted 389 manatees and I counted 336 while it was still drizzly and there was lots of fog coming off of the spring run, making IDing rather difficult. After the count was over, a big palm tree fell into the water at the boil and provided an immediate buffet for the manatees who gravitated to it. Park staff and I went to go check everything was ok—it was. I probably identified as many manatees while paddling back to check as I ID’d during the entire recorded count.

The adoptees in today were Brutus, Annie, Paddy Doyle, Moo Shoo, Alligator, Una, Lis, et pseudo.

~Cora

Jeudi 15 février 2024

The river temperature was back up to 66.5°F (19.2°C) which was a bit surprising as the air temperature has not really been very warm. The park counted 71 manatees and I counted 160 which was quite the difference, so I made sure to add everything up twice to double-check and also check how many I was able to identify. I ID’d over 100, making me believe that there must have definitely been that many. The conditions were great for counting, but there was a lot of manatee movement with them coming and going, so it is very possible that more came in after the park staff had finished their count. Annie et Una were the adoptees seen today.

~Cora

Wednesday, February 14, 2024

The river temp started back down and was at 65.8°F (18.8°C). We counted 83 manatees, none Save the Manatee Club adoptees. Maybe tomorrow.

Wayne & Cora

Tuesday, February 13, 2024

The river temp took a big jump to 66.6°F (19.2°C). We counted 25 manatees; some were going out, some were coming in, and some were just doing circles near the river. Few were up the run. None were Save the Manatee Club adoptees. In other environmental news, Cora spotted one alligator this season and that is the only one we’ve seen. Normally, we might see three to five on a roll call. I mentioned tarpon earlier. They have moved halfway up the run and no further. Usually we have wonderful photos of them all season in the Boil. The winter has been wetter than usual so the river has been higher. Perhaps that explains why.  Remember, if the manatees are not in their refuges, then they are in the waterways. Watch for them if you are boating!

Wayne & Cora

Monday, February 12, 2024

The river temp was up to 62.8°F (17.1°C), and manatee numbers have declined. We counted 42 manatees and none were Save the Manatee Club adoptees. The warming trend appears to be shorter than predicted, hopefully we will see more manatees and more adoptees soon!

Wayne & Cora

Vendredi 9 février 2024

The river temp was 61.9°F (16.6°C) so it was cooler than yesterday. But instead of going up, the number of manatees went down. I guess they know it is getting warmer. We counted 431 manatees. We had a good group of Save the Manatee Club adoptees. We saw Una, Brutus, Lis, Paddy Doyle, Philippe, Dent profonde, Phyllis, Moo Shoo & calf, Fusée, et Aqua. Moustaches was in yesterday but not mentioned. For those who remember, adoptee Success had four calves. Success and her two girls are gone now but the boys are still alive. We had not seen Success’ calf Cinna since the 2021–22 season. It was good to see him back again.

Wayne & Cora

Jeudi 8 février 2024

The river temp was 62.2°F (16.8°C). Media was in to film so I paddled them around and did what I could research-wise. Cora got a count from the boardwalk and I will use it. 492 manatees were counted. The Save the Manatee Club adoptees in were Paddy Doyle, Philippe, Phyllis, Brutus, Lénny, Aqua, et Lis. Looking ahead, more warm weather is on tap so the counts should go down.

Wayne & Cora

Wednesday, February 7, 2024

Today was the mass release of five manatees at the park. Two of the releases were rescued from Blue Spring and now they are back! They were greeted by over 500 manatees who were in the run today. The river was 62.4°F (16.9°C), which was enough reason to be in the run. Cora saw Save the Manatee Club adoptee Paddy Doyle.

I parked and then walked over to the run by the white house and saw Lis. Then I walked down to the big platform over the water and there, up against the corner of the platform under the webcam, was Brutus! That was a surprise. Participating in the release today were the Florida Park Service, Florida Fish and Wildlife Conservation Commission, United States Fish and Wildlife Service, SeaWorld Orlando, Clearwater Marine Aquarium Research Institute, Save the Manatee Club, Columbus Zoo, Georgia Aquarium, Brevard Zoo, Volusia County, and Texas State Aquarium Wildlife Rescue. Also many media outlets were present.

Tuesday, February 6, 2024

The river temperature this morning was 62.6°F (17°C) and the winds were up to gusts of 25 mph. Not an ideal day to count or identify manatees. The park counted 170 manatees, and SMC counted 165 from the canoe—that was extremely close given the poor conditions! The only adoptee in today was Lis.

~Cora

Monday, February 5, 2024

The river temp has been rising. Today it was 63.3°F (17.4°C). We only counted 158 manatees and none were Save the Manatee Club adoptees. However, it looks like the weather is going to cool and the rest of the week will be better for manatee viewing!

Wayne & Cora

Friday, February 2, 2024

The river temp was 62.6°F (17°C). That is warmer than yesterday, but still quite cold so manatees continued coming in. We counted 552 manatees, among them Save the Manatee Club adoptees pseudo, Paddy Doyle, Howie, Philippe, Dent profonde, Floyd, Alligator, Lis, Fusée, Una, et Moustaches. We are continuing to get new arrivals for the season.

Wayne & Cora

Thursday, February 1, 2024

The river continued to get cooler, to 61.9°F (16.6°C). The mist off the run was there again today, but not as bad as yesterday. We counted 491 manatees and the park counted 580 manatees. I think it was a good day for a boardwalk count. The Save the Manatee Club adoptees we saw were Howie, Paddy Doyle, Philippe, Lis, Una, Alligator, Phyllis, Floyd, et Moo Shoo. Moo Shoo was mixed in with over fifty other manatees so we did not see her calf to note it but the calf was undoubtedly in the mix somewhere!

Wayne & Cora

Wednesday, January 31, 2024

The river temp was 62.4°F (16.9°C) so it is getting colder. The park counted 280 manatees in a heavy mist with more manatees coming in. We counted 312 manatees with the mist rising and even more manatees coming in. We saw Save the Manatee Club adoptees Phyllis, Alligator, et Annie. Then we waited a while and released a manatee from down south who had been re-rescued, in the hopes that she will do better up here. Aside from SMC, SeaWorld Orlando, the Florida Park Service, CMARI, and FWC participated.

Wayne & Cora

Tuesday, January 30, 2024

Foggy today, and the mist off the run was thicker than any day this season. The river temp was 63.7°F (17.6°C). We counted 135 manatees and the park counted 149 manatees. In spite of the mist, we saw Save the Manatee Club adoptees Lis, Annie, Phyllis, Alligator, Moo Shoo, et Howie. Gator was especially good to see, as he has been gone for weeks. No attendance championship for Gator this season! We did get reports of him in other springs, so that was some consolation.

Wayne & Cora

Monday, January 29, 2024

The manatee festival is over, and the manatees are back! It got cold overnight; however, the river temperature only dropped slightly to 65.8°F (18.8°C). The park staff counted 42 manatees and SMC counted 68. The only adoptee present today was pseudo. Most manatees were close to the river still and the wind started to pick up to the predicted 17 mph gusts, so there was not much lingering after the count was over to identify more manatees. We expect many more for the rest of this week!

~Cora

Sunday, January 28, 2024

Second day of the Manatee Festival and the river temp was 66.4°F (19.1°C). I saw 22 manatees and none were Save the Manatee Club adoptees. Ten days ago, we found a manatee in trouble halfway up the run. It was emaciated and behaving lethargically. We got a rescue underway but before the rescue team could arrive, the manatee was gone. We searched for the manatee for some time, and every day thereafter we watched for them but they did not appear. Yesterday afternoon, they were found in the St Johns River near the park. The cause of death is not determined at this time. On a happier note, a review of the calves I have seen has raised the number of calves to 92. The previous record number of calves was set last year at 87 and we should see more before season end! The cold is returning, hopefully with more manatees and some adoptees.

Wayne

Saturday, January 27, 2024

The first day of the Orange City-Blue Spring Manatee Festival, and the river was up to 64.9F (18.3C). I counted thirty manatees and none were Save the Manatee Club adoptees! As it is in the eighties, I have little hope for tomorrow, but the manatees we had stayed visible all day. Plus, I found many people were fascinated by the nesting tilapia just behind the manatee viewing platform.

Wayne

Friday, January 26, 2024

The river had warmed up to 63.5°F (17.5°C) and the manatee count dropped accordingly to 59. No adoptees were seen today, but adoptee Annie made an appearance late yesterday afternoon.

Also yesterday, a new manatee joined our Blue Spring population; her name is Churro. Churro was rescued with her mother “Reckless” in May 2022, when Reckless suffered from a catastrophic watercraft injury to her left shoulder. Churro was estimated to only be a few days old. The pair was brought to SeaWorld Orlando for rehabilitation and, after 20 months of expert care, was released last week in South Florida by partners of the Manatee Rescue and Rehabilitation Partnership. Both manatees were outfitted with satellite tracking devices so their movements could be monitored. The hope was for them to stay together, so Reckless could teach Churro how to live in the wild. However, at 700 pounds, Churro was at the age where a calf would have usually been weaned. Unfortunately, the pair did not stay together and the decision was made to intervene and bring Churro to Blue Spring, a natural warm-water site with lots of other manatees. The hope is that Churro will learn from them and follow them. She was in the spring run this morning with the other manatees.

Thursday, January 25, 2024

The river temp today was 61.2°F (16.2°C). With the warm weather, the manatee count has been cut approximately in half each day for the past four days. Today, the count was 156 manatees. The only Save the Manatee Club adoptee in was pseudo. Looking forward to Saturday, my prediction is around forty manatees but manatees do not care what I predict!

Wayne & Cora

Wednesday, January 24, 2024

The river temp rose dramatically to 59°F (15°C). We counted 323 manatees. As the eighty-degree highs continue, I hope they leave a few manatees around for the Festival! We saw Save the Manatee Club adoptees Howie, pseudo, Paddy Doyle, Doc, and late but not least Philippe. Again today, the manatees in the run were mobbed up near the river, waiting to get out to the big salad bar to eat.

Wayne & Cora

Tuesday, January 23, 2024

The river temp went down a tiny bit lower overnight but with the warming today and the coming week, many manatees have gone out to feed and most of the others are near the mouth of the run, ready to go out when it warms a little more. We counted 626 today, and the Save the Manatee Club adoptees among them were Aqua, Dent profonde, pseudo, Paddy Doyle, Howie, Lis, Philippe, Fusée, Doc, et Phyllis.

Wayne & Cora

Monday, January 22, 2024

The river temp was 57.6°F (14.2°C). That is cold! At least for the past few seasons. Forty years ago it was often colder. Now for the fun part. We counted 717 manatees. I believe that is the highest one-day count I have participated in. We saw Save the Manatee Club adoptees Philippe, Merlin, Lis, pseudo, Annie, Doc, Phyllis, Fusée, Moustaches, Aqua, Dent profonde, Margarito, et Howie.

Wayne & Cora

Sunday, January 21, 2024

It was the coldest morning of the season yet and the wind made it feel even chillier. The river temperature was 58.8°F (14.9°C) and SMC counted 679 manatees. The park staff counted 932 from the boardwalk, but that seems rather high. IDing the manatees from the research canoe was very difficult today due to the high winds, but I still was able to see adoptees Aqua, Paddy Doyle, pseudo, Doc, Lis, Floyd, et Una. Howie was on the webcam yesterday. There is a very good chance that many more were in, huddled together so I was unable to identify them.

The river was down to 60.1°F (15.6°C). We counted 501 manatees today. With the drop in the river temp, the number of manatees might have increased but it should be warmer today. The manatees are eager to get out and eat and get ready for more cold days. The Save the Manatee Club adoptees in were Lis, Howie, Philippe, Una, Floyd, Merlin, Dent profonde, et Moo Shoo & calf.

Thursday, January 18, 2024

The river temp was 60.6°F (15.9°C). The park counted 677 from the boardwalk; during the count, the manatees conducted a huge panic, with many going into the river. So, when I counted from the canoe later, I counted 475. I saw Save the Manatee Club adoptees Howie, Philippe, Lis, Annie, Una, et Dent profonde. I have not seen a green heron for a couple of years but one was at the boil today. I love how they will crouch in an inch of water and think they are invisible.

Wednesday, January 17, 2024

The river temp was 62.1°F (16.7°C). We counted 300 manatees and the park counted 256. We saw Save the Manatee Club adoptees Howie, Lis, Lénny, Annie, et Dent profonde. Feeling that one of the manatees was in desperate need of assistance, we called, and a rescue was started. However, the sick manatee disappeared and a very long search did not find them, and the rescue attempt had to be called off. We also turned a floating park sign that had blown over back upright. It was not easy!

Tuesday, January 16, 2024

It was a warm and humid morning and the river temp was 60.9°F (16.1°C). The park staff counted 259 I counted 194 manatees, but I believe I may have undercounted. Most manatees were located near the river and many were moving in and out. The adoptees seen were Lénny, Howie, Annie, Floyd, Aqua, Dent profonde, et Paddy Doyle.

~Cora

Monday, January 15, 2024

The river temp was 60.8°F (16°C). Before the canoe launched, the manatees conducted a big panic that originated somewhere up the run out of my sight. So again, we started the count with bank-to-bank manatees near the river and the silt so churned up we could see very little in that area. We counted 525 manatees and the park counted 675. The Save the Manatee Club adoptees we saw were Howie, Phyllis, Annie, Moo Shoo & calf, Éclair, Merlin, Una, Aqua, Dent profonde, et Moustaches. Floyd also made an appearance on the webcam.

Sunday, January 14, 2024

The river was 62.4°F (16.9°C) and the park staff counted 353 manatees. I counted 377—pretty close! Something must have startled or annoyed the manatees in the upper part of the run, as they kept quickly swimming down the run when I was halfway through the count. Adoptees Una, Annie, Lis, Moo Shoo avec veau, et Éclair made the count today.

~Cora

I do not believe we have mentioned in the blog that Alligator has been seen recently in a spring other than Blue Spring and appears to be doing well. I just went through the figures on manatee attendance at Blue Spring and here they are as of today. 458 returned from last season, 15 returned from previous seasons, and 88 manatees that we cannot ID and will name and number at season’s end. 79 manatees we can ID this season but probably not next season, and 83 calves. The total is 723 manatees seen at least once this season. We have yet to get a handle on how many are in that are totally unmarked.

Saturday, January 13, 2024

We couldn’t do a count yesterday due to high winds and rain. It warmed up quite a bit and many of the manatees went out to feed.

The river was 62.6°F (17°C). The park staff counted 203 manatees and I counted 160. I may have undercounted slightly as there was a large cavorting group that started in transect 2 (by the second overlook) and made its way all the way up to the boil. I tried to keep my distance from it and could only estimate how many participants were involved. The only adoptees sighted today were Moo Shoo avec veau, Annie, et Éclair.

We have been wondering all season where the alligators were. Usually, we have at least one or two hanging out in the lower part of the spring run. It wasn’t until this morning that I finally saw one. It was close to the river. On the way back, an eagle chased a great blue heron. We usually see the eagle sitting on the very top of the tree by the river. I have never seen one on the side of the bank chasing another bird away. It was a sight to see for me and the many park visitors who witnessed it!

~Cora

Wednesday, January 10, and Thursday, January 11, 2024

Wednesday: Got my notes together to do the blog and then got distracted by a camera problem. Here it is, a day late. The river temp was 62.2°F (16.8°C). We counted 387 manatees and the park counted 342 manatees. We counted more as we were out a long time to keep track of Una so an attempt could be made to get some of the line entanglement off of her left flipper. Una took off before anyone could even get in the water. We also saw Save the Manatee Club adoptees Éclair, Lis, Aqua, et Fusée.

Thursday: The river temp was down to 61.5°F (16.4°C). The park counted 664 manatees and we counted 524 manatees. Our count was thrown off by a huge manatee panic of unknown origin that came down the run toward us. Many manatees went out into the river and the lower run was left so stirred up visibility was close to nil. We did observe Save the Manatee Club adoptees Howie, pseudo, Dent profonde, FloydPhyllis, Lis, Aqua, Doc, Moo Shoo & calf, and Lénny. Clearwater Marine Aquarium Research Institute personnel were back to try to help Una again today. More was learned about the entanglement, which may help in future efforts at removal but Una was not having anyone too close. So perhaps another day!

Wayne & Cora

Monday, January 8, 2024

We did not expect much today as the river had gone up two degrees to 62.1°F (16.7°C) since noon yesterday and the park had counted in the two hundreds over the weekend. I think they counted what they could see, which was not much as the weather was rotten and rain makes manatees almost impossible to spot. The park counted 612 manatees today, and we thought that was high until we counted 602 manatees. The manatees were calm, the surface of the water was like glass, and the overcast weather meant the sun did not ruin our films. The Save the Manatee Club adoptees we ID’d in the crowd were Lis, Una, Dent profonde, Doc, et Éclair.

Wayne & Cora

Friday, January 5, 2024

The manatee count went down. We counted 428 manatees and the park counted 499 manatees. The river temp was the same as yesterday: 60.1°F (15.6°C). The difference in the two counts today was probably a huge manatee panic in the lower run by the river. The run was so stirred up that little could be seen in that area. We could see no reason for the panic. It must have been a manatee thing! The Save the Manatee Club adoptees seen were Phyllis, pseudo, Dent profonde, Moustaches, Moo Shoo & calf, Éclair, Doc, Margarito, Annie, Lis, et Philippe.

Wayne & Cora

Thursday, January 4, 2024

The river temp rose, but not much to 60.1°F (15.6°C) so we counted 677 manatees and the park counted 687 manatees. Then, a young male manatee that was rescued from Blue Spring earlier this season was released. He had been treated for line entanglement on his left flipper at SeaWorld Orlando. He has been named Manatee Jones. It was a good day for Save the Manatee Club adoptees. We saw pseudo, Margarito, Dent profonde, Doc, Lis, Éclair, Una, Aqua, et Moo Shoo & calf.

Wayne & Cora

Wednesday, January 3, 2024

The river temp was 59.5°F (14.3°C), so it was down a little more than yesterday. I counted 575 from the canoe and the park counted 706 from the boardwalk. The park may be closer to the proper number, as I was still distracted by media in the canoe. It was a perfect day for roll call, and I hope it will be the same tomorrow. Save the Manatee Club adoptees pseudo, Howie, Lénny, Doc, Merlin, Phyllis, Floyd, Paddy Doyle, et Lis were to be seen.

Wayne & Cora

Tuesday, January 2, 2024

The river temp was down to 59.9°F (15.5°C). I counted (estimated) 516 manatees. The park counted over six hundred manatees. Cora saw Save the Manatee Club adoptees Floyd, pseudo, Lis, et Phyllis from the boardwalk (I was in the canoe). I had media in the canoe and the count is always a little off when that is the case. When I left the park, the line to get in was only about one or two hundred yards long. Friday, it was just over a mile.

Wayne & Cora

Saturday, December 30, 2023

The river temperature had cooled down to 61.7°F (16.5°C). The park staff counted 545 manatees and I counted 505. I may have underestimated, as they were packed in in some of the transects, making it impossible to really see. It was one of those days where it is easier to count from up on the boardwalk than from the research canoe. But there was no wind, which allowed for perfect ID conditions. The adoptees seen were Brutus, Aqua, Phyllis, Lis, Doc, Moo Shoo avec veau, Annie, Floyd, Una, et pseudo. Howie et Philippe were seen after the count was finished.

We still see new manatees arriving every day!

~Cora

Friday, December 29, 2023

The river temp was 63.5°F (17.5°C). We counted 358 manatees and the park counted 349 manatees. You cannot get much closer than that! The Save the Manatee Club adoptees present were Doc, Una, Phyllis, et Moo Shoo & calf. Then some time was spent with the media. The line to get into the park at 1245 must have been over two miles long.

Wayne & Cora

Wednesday, December 27, 2023

The river temp was 64.2°F (17.9°C). We counted 186 manatees and the park counted 191. Pretty close. There were some in the river when we counted that may have just gone out. Most of the manatees were near the river, wanting to get out and eat before the next cold comes in. Conditions were as good as yesterday until the wind came up but the roll call was over by then. The Save the Manatee Club adoptees in were Annie et Floyd.

Wayne & Cora

Tuesday, December 26, 2023

The river temp was 63.7°F (17.6°C). We counted 225 manatees. The ten-mile-per-hour wind never arrived while we were out, nor did the fog, but the rain did a little. The manatees were very calm, and the water was like glass—no mud, no silt. We were glad we did not cancel the roll call. Floyd, Doc, et Annie were the Save The Manatee Club adoptees in.

Wayne & Cora

Friday, December 22, 2023

We knew the river temp was 61°F (16.1°C). That meant the river was a little warmer than yesterday, and I was not surprised to see water swirls indicating manatee activity by the river. They would want to go out and feed. But the condition of the run, I had never seen before. Half the run near the river was suspended mud, the other half beyond murky. Manatees were everywhere and spooky. Even the paddle in the water upset some. All sorts of debris was coming down the run. Leaves, twigs, pieces of palm frond, and patches of foamy bubbles. We moved over near the east bank, where we were less likely to hit a manatee, and eased up the run. A visitor was on the large viewing platform where our above-water camera is located. He said earlier that he was on the aluminum dock halfway up the run when the manatees jammed in front of it erupted. Foam, tails, waves, and manatee backs thrashing everywhere. When we got to the dock, the water there had cleared and we began our roll call. Normally, we start by the river, but nothing could be seen there. We went to the boil to do the roll call and then suspended it until we returned to the aluminum dock on the way back down. We resumed the roll call there as the water had cleared and the manatees were calmer. Something may have happened during the night to make them nervous and ready to “panic,” or they may have upset themselves. We managed to count 573 manatees, including Save the Manatee Club adoptees pseudo, Moo Shoo & calf, MoustachesDocPhyllis, Annie, Alligator, Lénny, et Merlin. With Doc in, we are only missing Lucille.

Wayne & Cora

Thursday, December 21, 2023

Good old, beat up, Merlin showed up today! Now we only need Doc and Lucille. The river temp was down to 60.6°F (15.9°C). We counted 669 manatees, but we probably missed many in the lower run as the manatees were cavorting and stirring up the silt. Aside from Merlin, the Save the Manatee Club adoptees in were pseudo, Philippe, Dent profonde, Lénny, Aqua, Floyd, Moo Shoo, Phyllis, Moustaches, et Alligator. We must have done a good job of IDing going up the run because we hardly ID’d any going back down the run.

Wayne & Cora

Wednesday, December 20, 2023

The river temp was 61.7°F (16.5°C). This was the best day we have had for roll call this week. The wind was 5 to 15 mph, mostly 5 mph, or we were in a place out of the wind on the run. We got a count of 685 manatees! The Save the Manatee Club adoptees we saw on the way up the run were Philippe, Alligator, Annie, Phyllis, Moustaches, Dent profonde, Aqua, Floyd, et Moo Shoo. Moo Shoo was in a mob near the shore and we could not find her calf, but we are sure the calf was there. On the way down the run after roll call, we had a regular line-up of adoptees; we saw Paddy Doyle, Lis, Brutus, et Howie. Today, as on several other days, we noticed the lack of tarpon. When we were almost to the mouth of the run to beach the canoe, we saw one, then two, then many more. Twenty or thirty were hitting the surface in front of the big viewing platform! I wonder where they have been?

Wayne & Cora

Tuesday, December 19, 2023

The river temp was 64.2°F (17.9°C). A little cooler than yesterday, so more manatees. We counted 401 manatees, and the park counted 431. The wind conditions were awful, but it was worthwhile. I definitely feel it was an undercount by us and the park both. The Save the Manatee Club adoptees were pseudo, Alligator, Moustaches, et Phyllis. Phyllis was seen after the count but was probably there the whole time. Sadly, we have been informed of the death of Leena. Leena was the calf of our departed adoptee Lesley. She was rescued with her mother and, when released, had no ID scars. She did have a microchip in her shoulder, so we know it was her. Now we would like to see if she has scars that may indicate she has been coming to Blue Spring since her release. We only know Leena has died now; more info will follow.

Wayne & Cora

Monday, December 18, 2023

The river temp was 65.3°F (18.5°C). The river was warmer, the manatees were fewer! We counted 279 manatees. But many were manatees we had not seen yet this season. Our Save the Manatee Club adoptees were Brutus, Moustaches, et Annie. One of our new sightings on the 15ème was Diago. He has been gone for four years. He was so comfortable at Blue Spring, I was surprised he left us after three seasons, but now he is back! Conditions for ID’s were terrible today. Wind and murky water.

Wayne & Cora

Saturday, December 16, 2023

I have been doing a little counting on the manatees we have recorded in this season so far. 370 manatees have returned from last season. Eight manatees have returned from previous seasons. We have counted 77 calves. 128 manatees are marked but not ID’d, and I estimate 37 manatees with no visible scars, for a total of 620 individual manatees seen so far this season. I expect at least 100 more known individuals. Throw in a few more unknown manatees coming in, and we may be in the 800’s again!

Wayne

Friday, December 15, 2023

The wind predictions were hefty, making it seem like a count today was out of the question, but luckily the wind didn’t start picking up until about 9:45 a.m.

The river temperature was 66.2°F (19°C), which again seemed pretty high; most likely it was influenced by the spring water. We found out this week that there is a temperature gauge in Deland, which read 63.8°F (17.7°C) this morning, and that makes more sense for the river temperature. The park counted over 400 manatees, and I counted 383. Conditions weren’t great for counting because the manatees had the water stirred up and a large group was cavorting halfway up the run and kept moving all the way up to the boil, picking up more and more participants along the way.

The SMC adoptees seen today were Howie, Brutus, Dent profonde, Phyllis, Annie, Moo Shoo avec veau, Floyd, Alligator, Lis, Philippe, Paddy Doyle, et Aqua. This was Aqua’s first visit for the season and should make a lot of adoptive parents happy, as we have been getting a lot of questions about her whereabouts. We are still waiting to see Lucille, Doc, and Merlin, but new manatees are still coming in daily.

~Cora

Wednesday, December 13, 2023

The river temp we got today was 65.3°F (19°C), which we considered even worse on the high side than yesterday. I was recently informed that the St Johns River Water Management District (SJWMD) has got the USGS to open a gauge at Whitehair Bridge near Deland. I just checked it out, and it is more reasonable than what we were getting the past two days. The USGS temp was 63.5°F (17.5°C). We counted 542 manatees this morning. A new high for the season. The Save the Manatee Club adoptees in were Dent profonde, Brutus, pseudo, Alligator, Lis, Moo Shoo & calf, and Phyllis.

Wayne

Tuesday, December 12, 2023

The river temp was 65.3°F (18.5°C). We felt it should be lower and that the spring run must be influencing our reading. At any rate, we counted 343 manatees, and the park counted 387. The wind was predicted to give us trouble seeing the manatees and controlling the canoe, but as often happens, by coming out early, we finish the count before the wind is too high. More manatees continue to make first appearances and more calves are coming in. Our Save the Manatee Club adoptees present were Lis, Annie, et Alligator. We are still looking for Aqua, Doc, Lucille, and Merlin.

Monday, December 11, 2023

The weather forecast called for 15 mph winds with 20 mph gusts—not a day to go out counting manatees from the research canoe!

I was headed to the park anyway to work on the webcams, and once I arrived, it was dead calm with barely any wind at all. It didn’t start picking up until I was halfway through the count.

The river temperature was back up to 19°C (66.2°F), and I counted 138 manatees. The park staff counted 141, so pretty close! None of them were Save the Manatee Club adoptees. However, adoptees Howie, Lis, et Annie were on the webcam over the weekend when we didn’t do a count.

Watching the webcam after, I saw many more coming in as the wind picked up and it continued to get chillier. More should be in tomorrow.

~Cora

Friday, December 8, 2023

The river temp was 62.6°F (17°C), which makes more sense than yesterday’s, which was just too high to be correct. Researchers were in the water, so the manatees were stirred up and harder to count and ID. We did some special temps for the SJWMD. While we did that, the manatees calmed down some. Then, a third of the way into the count, a helicopter hovered over the run, and the longer it stayed, the more manatees fled the run. Cora and I had trouble hearing one another because of the noise from the aircraft. We could still count, but IDing was much harder. We managed to count 511 manatees, and the park counted 492 manatees. I consider those counts close enough to be considered the same. More new arrivals and calves keep coming in! Our Save the Manatee Club adoptees today were Brutus, Paddy Doyle, Moo Shoo & calf, Éclair, Alligator, Lis, Annie, Phyllis, Philippe, et Howie.

Wayne & Cora

Thursday, December 7, 2023

The river temp was 66.2°F (19°C), which is totally wrong. The run must have been pushing south and effecting the thermometers. The 371 manatees we counted showed the true condition of the river. The park counted 438 manatees. We count at different times and from different angles, so the counts nearly always differ. The Save the Manatee Club adoptees present were Lis, Annie, Una, Alligator, Fusée, Moo Shoo & calf, and Dent profonde.

Wayne & Cora

Wednesday, December 6, 2023

The river was back down to 64.4°F (18°C). We counted 202 manatees. Among the Save the Manatee Club adoptees, Éclair was in for his first visit. Una, Lis, et Alligator were also in.

Wayne & Cora

Tuesday, December 5, 2023

The river was warmer than yesterday, 68°F (20°C), but the air the manatees were breathing was cooler, so our count ended up higher than expected. We counted 105 manatees. I could see something coming down the run from where I was at the tour boat dock. It was a rotting palm tree, and two juvenile manatees were gnawing on it. My thanks to Alligator the manatee for showing up, so we at least had one Save the Manatee Club adoptee present!

Wayne

Monday, December 4, 2023

The river temp was 67.1°F (19.9°C). It was obvious the count would be down as we saw manatees that were normally up the run and even in the boil down by the river. Sure enough, only two were above the first quarter of the run. We counted 79. The park had counted 107 earlier. No Save the Manatee Club adoptees were present. Our highlight was to see one of the manatees that was released last year and had lost its tracking gear during the summer was back and looking fat and healthy.

Wayne & Cora

Saturday, December 2, 2023

The weather is really warming up, and the river was up to 67.1°F (19.5°C). The count was off to a late start because a family from the Wish Upon A Star foundation was visiting the park so their young child could see his first manatees, and he got to see quite a few!

Most of the manatees were headed towards the river and I counted 236. The adoptees in today were Alligator, Annie, Fusée, et Dent profonde. We are still seeing new manatees arriving every single day and lots of calves. The forecast looks warm for the next few days, which will allow the manatees a little break to go feed in the river before the next cold front is forecasted for mid next week.

Also of note are two manatees, Nato and Jaden, who we closely monitored alongside our partners last season. Both had suffered injuries from collisions with watercraft and Nato in particular escaped several rescue attempts. Luckily, he healed well and is back at the spring this season—he is one of the lucky ones. Same for Jaden.

~Cora

Friday, December 1, 2023

The river temp was up to 65.3°F (18.5°C), and the air temp was headed to 83°F (28.3°C). I think the manatees knew this, as many were abandoning the run as we started the count. Then the leaf blower started up and inspired even more manatees to leave. They were hard to count! In the end, we counted 433, which goes nicely with yesterday’s count of 447. The Save the Manatee Club adoptees in today were Margarito, Paddy Doyle, Howie, Una, Annie, Brutus, Floyd, Alligator, Moo Shoo & calf, and Deep Dent. Gator was also in yesterday, I missed mentioning him. The brief spell of warm weather may cause some lower manatee numbers but right now we could use a breather to study our pictures and drawings.

Wayne & Cora

Thursday, November 30, 2023

The river temp remained at 64.4°F (18°C), and the manatees kept coming! We counted 447 manatees and, like yesterday, they had the run so stirred up that there must have been many more in the murky water. It was an adoptee party. We saw Philippe, Howie, Annie, Lis, Una, Moo Shoo & calf, Phyllis, Paddy Doyle, Lénny, et pseudo!

Wayne & Cora

Wednesday, November 29, 2023

The river temp only went down a little to 64.4°F (18°C), but the number of manatees went way up. We counted 270, and if the water had been clear, we probably would have counted over 300. The Save the Manatee Club adoptees present were Moo Shoo & calf, Deep Dent, and two new arrivals for the season—Moustaches et Fusée! As of yesterday, I said we had 132 manatees in so far this season. That should have been 132 calves and returned manatees. We have seen many more total manatees! As of today, at least 270.

Wayne & Cora

Tuesday, November 28, 2023

The river temp is down to 65.3°F (18.5°C), and we counted 179 manatees! Tomorrow should see many, many more! The Save the Manatee Club adoptees in today were Moo Shoo & calf, Annie, et Deep Dent. All were over halfway up the run. 93 manatees have returned from last season so far. Two were not seen last season but are here now. We already have 37 calves. This works out to a total of 132 individual manatees seen as of today!

Wayne & Cora

Monday, November 27, 2023

The season is underway, for certain! We counted 124 today and the predicted highs and lows for the next few days are in the forties (below 10°C). As for Save the Manatee Club adoptees, Moo Shoo & calf, who have been in several days, were joined by Deep Dent.

Wayne & Cora

Saturday, November 25, 2023

The river temperature was 68°F (20°C) and, for the first time this season, the count broke 100! The park staff counted 106 manatees from the boardwalk and I counted 113 from the research canoe. The manatees were extremely active in the lower part of the spring run, cavorting around the logs, which made counting and identifying difficult. Luckily, on the way back down, they had settled some, so I was able to pick out a few more IDs. The only two adoptees in were Annie et Moo Shoo avec son veau. Tous deux se trouvaient dans la zone près du belvédère en aluminium, ce qui permettait aux visiteurs d'avoir une bonne vue sur eux. D’autres adoptés devraient bientôt arriver !

~Cora

Vendredi 24 novembre 2023

La température de la rivière était de 67,8°F (19,9°C) et j'ai compté 68 lamantins. Un adopté du Save the Manatee Club en faisait partie. Annie. Elle était juste à côté de la promenade, donc elle avait une petite foule de spectateurs. Côté recherche, le 21 novembre, Cora a filmé Hola avec un veau. Nous ne l’avions pas vue depuis janvier 2017. J’avais peur qu’elle soit décédée pendant l’épidémie de COVID et qu’elle ne s’en soit jamais remise, ce fut donc une très agréable surprise de la revoir.

-Wayne

Jeudi 23 novembre 2023

La température de l'air a chuté de façon drastique pendant la nuit, passant d'environ 80 degrés hier à 50 degrés ce matin. Cependant, la rivière ne semblait pas avoir beaucoup baissé ; il faisait encore 23°C (73,4°F) selon mon thermomètre. Le personnel du parc a dénombré neuf lamantins et j’en ai compté 18 – ils semblaient juste arriver. Aucun d’entre eux n’a été adopté, mais les températures plus fraîches des prochains jours devraient faire venir quelques lamantins.

Joyeux Thanksgiving à tous !

~Cora

mercredi 22 novembre 2023

La température de la rivière était de 73,4°F (23°C). C'est plus de cinq degrés au-dessus des 68 degrés magiques qui commencent à attirer un plus grand nombre de lamantins. Ce n’est pas étonnant que nous n’ayons compté que trois mineurs ! Nous avons également compté trois cerfs. Deux étaient au kiosque qui surplombe l'ébullition. Je n'en avais jamais vu auparavant. J'ai inclus une photo du jeune qui a été sauvé hier car j'ai oublié de l'inclure hier. Cora l'a choisi pour les réseaux sociaux, et je l'ai choisi pour le blog, donc ça doit être la meilleure photo. Il est censé faire plus frais après Thanksgiving, alors espérez qu'il y ait plus de lamantins !

Wayne & Cora

mardi 21 novembre 2023

Aucun décompte approprié aujourd'hui par Save the Manatee Club mais le parc en a dénombré 13. Au lieu de cela, nous avons eu un sauvetage. Un jeune lamantin mâle a été observé il y a quelques jours par différentes personnes avec une ligne enchevêtrée sur sa nageoire gauche. Il ne semblait même pas l'utiliser. Des photos ont été transmises et aujourd'hui, un sauvetage a été effectué par FWC, Sea World, Volusia County, Florida Park Service et Save the Manatee Club. Le jeune a été désigné S14/23. Le S signifie saisonnier, ce qui signifie que nous n’avons pas beaucoup d’espoir de l’identifier la saison prochaine. Nous avons maintenant plusieurs lamantins avec des enchevêtrements dans la nageoire gauche et nous ne pouvons pas les distinguer. Il est le 14ème lamantin vu cette saison dans cette catégorie. Le 23 représente la saison des lamantins 2023-2024. Une fois qu'il sera réhabilité et ramené à la source, cela changera, car il aura une puce d'identification, un nom et un numéro Blue Spring. Il est peut-être difficile à identifier visuellement, mais si quelque chose lui arrive, nous le saurons.

La température de la rivière était de 69,8°F (21°C) et nous avons dénombré 13 lamantins remués, tous sauf un au bord de la rivière. Les chercheurs étaient dans l'eau. Une fois le décompte terminé, les lamantins s'installaient et le décompte était plus proche de celui du parc, soit 17. Les températures peuvent être un peu plus fraîches plus tard dans la semaine, mais le temps est censé être humide et venteux. Pas de lamantins du Save the Manatee Club aujourd’hui.

La température de la rivière était de 71,6°F (22°C), ce qui était à peine plus frais que la température printanière. Le parc comptait 18 lamantins et moi 25, mais il y avait beaucoup de va-et-vient. La plupart des lamantins gambadaient près de la rivière ; quelques-uns étaient en amont. En remontant la piste, j'ai été surpris de ne voir aucun couple maman/petit, qui à cette période de l'année sont généralement les premiers à se présenter (nous en avons déjà vu beaucoup !). Une mère/un petit se trouvait entre l'entrée de baignade et l'entrée du plongeur, avec deux jeunes mâles poursuivant la mère agacée. Alors que je terminais le décompte et que je pagayais en aval, au moins trois autres couples vache/veau sont apparus, tandis que la plupart des lamantins que j'avais réellement comptés étaient depuis partis dans la rivière pour être remplacés par d'autres que je n'avais pas vus pendant le voyage. décompte officiel. Parmi eux, aucun adopté SMC n’était présent aujourd’hui.

Hier, la météo était si défavorable que nous n'avons pas fait de décompte. Aujourd'hui, c'était presque pire avec de la pluie et des vents violents, et il fait encore très chaud étant donné que nous sommes à la mi-novembre. La température de la rivière était de 68,9°F (20,5°C) et 5 lamantins ont fait le décompte officiel. Quatre autres personnes sont arrivées une fois le décompte terminé, mais aucun n'était un adopté.

Il a fait très chaud ces derniers jours et seuls quelques lamantins ont été aperçus par les observateurs bénévoles ce week-end. Aujourd'hui, la température de la rivière était de 71,6°F (22°C) et aucun lamantin n'était présent lors de la migration printanière. Nous ferons attention aux températures plus fraîches !

La température de la rivière était de 71,6°F (22°C). Douze lamantins ont été dénombrés. Aucun n’était un adopté du Save the Manatee Club. Rien d'autre à signaler !

Jeudi 9 novembre 2023

La température de la rivière était de 71,6°F (22°C). Nous avons compté 30 lamantins et aucun n’était un adopté du Save the Manatee Club. Quelques nouveautés pour la saison sont arrivées, mais il faudra attendre un temps plus frais avant que les chiffres n'augmentent.

mercredi 8 novembre 2023

La température de la rivière a légèrement augmenté. Il faisait 68,2°F (20,°C). Le nombre de lamantins est tombé en conséquence à 53. Le seul adopté par le Save the Manatee Club pour le décompte était grand. Lis, et c'est toujours bon de la voir. La webcam a montré Moo Shoo et un veau en fuite avant le décompte d'hier, donc le total des adoptés est de quatre : Annie, Alligator, Moo Shoo, et Lis. Seuls deux des veaux observés hors saison restent à voir. Pour l’avenir, les températures se réchauffent, mais une brève tendance au refroidissement s’installera dimanche.

Encore un jour comme aujourd'hui, et je déclarerai que la saison des lamantins a commencé hier ! La rivière est restée à 68°F (20°C). Cora et moi avons compté 62 lamantins et en avons identifié 33. Parmi eux se trouvaient les adoptés du Save the Manatee Club. Annie et Alligator. Nous avons enregistré douze veaux pendant l'intersaison, et sept d'entre eux sont rentrés. Pas mal pour deux jours ! Une fois que nous voyons un veau, nous nous inquiétons de son arrivée au refuge pour l'hiver.

lundi 6 novembre 2023

Le personnel du parc et les observateurs bénévoles des lamantins ont vu de nombreux lamantins le week-end dernier. 

Ce matin, la température de la rivière était de 68°F (20°C), ce qui est considéré comme le « chiffre magique » pour amener les lamantins au printemps. J'en ai compté 76, et ils ont été dispersés tout au long de la course printanière. Plus que ce à quoi je m'attendais ! La plupart d’entre eux étaient soit des juvéniles, soit des couples maman/petit, qui arrivent généralement en premier. Pas d'adoptés ce matin, mais Annie a été aperçu ce week-end.

Vendredi 20 octobre 2023

J'ai mesuré la température de la rivière aujourd'hui et, à ma grande surprise, elle indiquait 69,8°F (21°C), ce qui était bien inférieur à ce à quoi je m'attendais. Cependant, en vérifiant les températures de l'air hautes et basses au cours de la semaine dernière (ce que nous faisons régulièrement pendant la saison sur la station météorologique installée par le service du parc), j'ai vu que les températures minimales nocturnes au parc se situaient en fait dans la partie supérieure. 40 cette semaine – un peu plus frais que ce que prédisent les prévisions météorologiques en ligne pour le centre-ville d’Orange City. Ceci, en plus des nombreuses pluies tombées avant les fronts froids, pourrait avoir contribué à la baisse de la température de la rivière.

J'ai tenté de compter, mais il semblait que personne ne voulait être compté aujourd'hui : aucun lamantin n'était présent lors de la migration printanière à 8 heures du matin. Plus tard dans la matinée, quelques-uns sont arrivés, dont Amelia, un lamantin que nous avons aidé à relâcher il y a quelques années. C'était bon de la voir et elle était superbe. Il nous a fallu un peu de temps pour reconnaître une autre femelle lamantin, « Chloé ». Elle a eu une nouvelle grève (pas grave) de bateau au cours de l'été qui lui a laissé trois petites cicatrices au milieu du dos, c'est tout ce que nous avons pu voir sur la webcam. Nous identifions Chloé par une cicatrice blanche sur sa nageoire gauche et une cicatrice enchevêtrée sur sa nageoire droite, ainsi qu'une petite entaille sur le côté gauche de sa queue. Aujourd'hui je l'ai bien vue, et c'est bien Chloé, et elle a un veau ! C'est peut-être son premier petit. Nous avons aidé au sauvetage de Chloé il y a deux saisons, et elle a été amenée à SeaWorld pour y être rééduquée en raison de son comportement léthargique, de sa perte de poids et de l'enchevêtrement de sa nageoire. Heureusement, elle a connu un redressement rapide et a été libérée plus tard dans la saison.

La semaine prochaine s’annonce très chaude, il est donc fort probable que les lamantins retournent dans la rivière. Aucun adopté n’a été vu aujourd’hui.

Nous avons eu une petite vague de froid en Floride cette semaine !

Les températures de l'air sont tombées dans les années 50 à Orange City et quelques lamantins se sont arrêtés à Blue Spring au cours des derniers jours. Bien que notre équipe de recherche n'ait pas encore effectué de décomptes officiels, nous les avons surveillés via notre webcam (ils seront rendus publics en novembre) et nous avons reçu des rapports des observateurs bénévoles des lamantins. Mardi, environ 13 à 20 lamantins ont été aperçus ; mercredi, le nombre est passé à environ 20 à 25 lamantins ; et aujourd'hui (jeudi), l'observateur a signalé 29 heures du matin seulement. Beaucoup d’entre eux sont des juvéniles indemnes, et la majorité arrivent au printemps et repartent rapidement, il est donc difficile de tenir un décompte précis. Il ne fait pas encore assez froid pour qu’ils veuillent rester. Nous en avons observé plusieurs dévorant la végétation flottante présente au printemps, ce qui était prévisible ! Beaucoup de végétation avait été soufflée lors de la descente printanière, en particulier après l'ouragan Idalia, ce qui a rendu plus difficile le passage des pagayeurs, y compris de nos observateurs de lamantins. Cela ne devrait plus être un problème !

Nous étions ravis de voir de nouveaux couples maman/petit et plusieurs lamantins déjà relâchés qui semblaient se porter très bien. L’observation du lamantin Plantaina, que nous avons aidé à relâcher à Blue Spring en 2022, après qu’elle n’ait pas réussi à prospérer sur son lieu de libération d’origine, a été particulièrement excitante. Elle a été jugée réussie l'hiver dernier par nos partenaires du CMARI après être revenue à Blue Spring en bonne condition physique. Elle a nagé devant la webcam avec un groupe d'autres lamantins hier, et nous avons dû faire une double prise pour confirmer que c'était bien elle tellement elle est devenue grande ! Le seul adopté vu cette semaine était Annie.
Comme il ne fait pas encore toujours froid, les lamantins s'arrêtent généralement pour une très brève période de temps puis repartent dans la rivière Saint-Jean. Nous commencerons nos décomptes officiels une fois que le temps sera constamment froid.
