28 June 2024

Hello Everyone,

Thursday was not a good day. Indeed, it has been tearful and solemn. Our beloved Louis at Loch Arkaig has not been seen on camera since 1151 local time on Wednesday. Intense storms with gale-force winds in the area almost blew the two osplets off the nest. Dorcha is trying to keep them safe, and she did fly off and returned with an eel so they would have something to eat. Geemeff writes, “Only one fish yesterday, and just the tail end of that. No fish today, so Dorcha went off and came back with an eel. Concern is growing for Louis.”

Many of you will have watched Loch Arkaig nest 1 during the pandemic where Louis and Aila raised three amazing osplets, JJ5, JJ6, and JJ7. Sadly Aila did not return and he bonded with Dorcha. Louis moved them from the Loch Arkaig nest 1 to the current nest where, sadly, the weather is worse. Louis has always been an amazing provider. My heart is breaking. It feels like someone hit me really hard in my abdomen. This just can’t be happening.

As Thursday passes, concerns continue to grow as Louis has not been seen all day after being perched in his favourite tree late on Wednesday by Liz Bracken who can view the area with her scope.

Dorcha is feeding the chicks but eating very little herself. She needs to eat, too. Oh, please come home safe, Louis.

Dorcha is desperately trying to protect her two chicks during the storm.

Geemeff’s report for Loch Arkaig:

Daily summary Thursday 27th June 2024

Midnight finally arrives to end a dreich day filled with worry over Louis – where is he? The usually reliable super-fisherbird hasn’t been seen for over 24 hours, and concern is growing. He only brought a partial fish to the nest yesterday and Dorcha and the chicks are hungry. So taking matters into her own talons, Dorcha went off and returned with an eel which she proceeded to feed to the very eager chicks, once again, she didn’t get much herself. Dorcha’s fish (yes, eels are fish) takes the tally to two hundred and fifty one. Despite the official forecast the weather has been atrocious and at one point, both chicks were nearly blown off the nest in a violent gust of wind. What’s described as a ‘moderate breeze’ and heavy rain soaking the nest and its occupants is set to continue until tomorrow afternoon when there is a prospect of some sunshine. As the chicks’ plumage isn’t fully waterproof as yet, Dorcha still needs to act as mumbrella to shelter them, which she can’t do if she’s off fishing. With luck, Louis will turn up tomorrow. No action on Nest One.

This is the latest news from The Woodland Trust:

After taking advice we have decided to place some fish on the nest today if Louis or Dorcha do not bring anything in meantime. This could be within the next hour or two subject to legal clearance. The camera may be switched off for this to happen. Given the weekend is approaching, a licence is also being sought to remove the chicks from the nest so we have that option over the weekend if we need it. The advice we have received is that if Louis has not returned by the end of the weekend, then he likely will not be returning. That being the case it is unlikely Dorcha would be able to successfully raise the two chicks to the end of the season and migration. Even given her best efforts to protect them and fish, they would likely not make it. Enquiries have revealed that among the options there is potential for the chicks to go into an existing translocation programme for the benefit of the species. We won’t commit to that until we are sure Louis and Dorcha don’t have a good chance of continuing undisturbed to raise their family. The tricky thing is not intervening too soon when Louis might turn up at any moment, and not leaving it too late until the chicks won’t be in good enough condition to survive translocation. The advice we have is that it is too soon to write Louis off yet, but if he continues to be absent until late into the weekend then we should look at removing the chicks then. The licence to do that is being sought today, even if it is not needed in the end. In order to increase the chance of a successful outcome for the chicks should they be removed in a few days time, they are going to be fed today to tide them over for now. They may also be fed tomorrow. To provision the nest Lewis will climb the tree and leave fish. You will appreciate we have a lot to sort out and I may not be able to answer the many questions I am sure you will have. So please bear with us.

If you are interested in Ospreys in Canada, I have just joined the very informative Ospreys of Nova Scotia FB group run by Connie Dennis, who monitors the nest of Ethel and Oscar at Russell Lake in Dartmouth, Nova Scotia. Connie told me that the birds in Nova Scotia have “lots of fish”. My goodness, that makes me want to dance!

There are no streaming cams but if you want to see some pretty well-fed babies head over to that group!

The trio at Charlo Montana – Charlie and Lola’s kids – are doing well. It has been raining but fish has come in and they seem fine.

I wish every nest had a Finnegan and, like all of you, I continue to be overjoyed that Iris has such an incredibly amazing wonderful magnificent mate!

‘A’ comments: “at Hellgate, Finn removed the fish from the nest around 07:15 and it was so heavy, he could hardly drag it off the nest, let alone lift it! I wondered why he didn’t just eat on the nest and feared he would drop it. And it appears that’s what must have happened, because although he had a good crop when he next returned, it was nowhere near the size it would have been if he’d eaten even a third of that fish. So obviously, he has dropped it, which is unfortunate, as it would have fed the entire family at least four big meals today. When Finn does come back at around 08:35, it is not with the remainder of the fish but with a huge branch. He then manoeuvres it into position and moves another large branch further around the nest. It appears he has noticed, as I have over the past 36 hours or so, that Big Bob is beginning to become very adventurous and is exploring the surface of the nest and heading out towards the rails on his own, sometimes even ending up out there at 3am and having to be brought back into the warmth of Iris’s underfluffies. Big Bob really does look to be right in the middle of his reptilian phase (I have to believe now that he is also a male, given how incredibly laid-back he is and how he tolerates Baby Bob in front of him for feedings, waiting to reach over to get a bite once Iris has stopped giving Little Bob consecutive bites, often for some time. Yesterday evening, she was feeding Little Bob for so long that I became worried Big Bob would lose patience, leaning over Little for a bite and continually missing out. Surely, he would become frustrated by this sooner or later. But no. Mum just kept feeding Little Bob until, essentially, he was too full to compete and sat down. The rain has now really set in (it’s nearly 9.30am and the camera keeps freezing) and although poor Iris is saturated, she still manages to keep both osplets absolutely dry. She is truly amazing – and the best mumbrella ever in both rain and sunshine. This is the most magical nest. First, of course, we have the gift from the gods that is Finnegan. Then, we have two viable eggs, both Finn’s, laid a full week apart, which both hatched. As if that were not enough, despite the serious concerns raised by the massive time and size discrepancy between the two hatches, we discover we have a second chick, nowhere near as well developed at hatch than was its much larger older sibling, that somehow still manages to get itself fed without any fear of getting to mum’s beak (once he could see it). And now, to cap it all off, we have a much older, larger sibling deep in the reptilian phase who still has not raised a talon or a beak in anger towards his younger sibling. So I can only think we have two brothers here. Surely even parents as devoted as Iris and Finn have demonstrated themselves to be could not have controlled the sibling aggression to this degree with a female first hatch and a male second hatch. It has been one miracle after another.  Still, as we have seen, Iris is an amazingly experienced, patient and dedicated mum. She never ceases to impress me. And as for Finn, what a man. He has his quirks, but Iris really has found a keeper in this handsome, devoted young mate. You go girl! What a cougar she is. Oh don’t you just ADORE the way he feeds her? ” She continues, “I do wish Finn would stop removing the leftovers from the nest. He eats a huge meal from them, then doesn’t feel hungry and obviously doesn’t realise that the chicks cannot eat enough to get them through the long gaps between fish deliveries that are the result of this behaviour. It would be far better if Finn caught much smaller fish, but these gigantic fish that seem to be the only thing on offer at this location will be great in a few weeks’ time but at this stage is proving annoying. Still, Iris is ensuring that the babies are fed into a food coma every time she has the opportunity to do so, even if it means sacrificing the time to eat properly herself on occasion. Finn has fought her for the fish more than once while she is feeding the osplets, and she has had to insist that he leave it alone until she’s finished. (It’s as if he wants to show the fish off, then take it away and eat the head before returning it. But of course this excites the chicks, who then wonder what has happened to the fish, so Iris argues loudly about it and usually wins – at least temporarily.) It is this particular quirk of his that does lead me to believe this is his first time. He should know by now that babies need small, frequent feedings not two or at most three massive feedings a day. “

At Field Farm, all four osplets are feathered and accounted for! ‘A’ writes, “Mini was self-feeding at Field Farm yesterday. What a cutie he is. All four are looking wonderfully well. “

CJ7 and Blue 022’s chicks should be getting ringed soon. They, too, are doing quite well. Dedicated parents, good fish supplies. It all makes a difference.

Steelscape appears to be doing alright.

Salt Point is good.

At the Newfoundland Power nest, Hope continues to feed her chick.

At Minnesota Landscape Arboretum, Mum is feeding the only surviving baby, too. Some relief. I hope these two mothers continue.

A message from Kelly Sorenson of the Ventana Wildlife Society:

My link to Thursday’s Condor Chat did not work. I asked ‘B’ to let me know if they found out anything about Aurora’s death. Here is what he reports, “There is no definitive answer on the cause of death for Aurora, but the possibility VWS considers to be most likely seems to be possible lead poisoning from contaminated prey that was fed to the chick.  This is mainly because they report that they are seeing high lead concentrations in many of the birds that they have trapped.  They were not able to recover Aurora’s body for analysis because the nest tree was so compromised by the Dolan fire that it would be too risky for a climber to retrieve the body.  VWS says that Zenith, the father, consumed the remains, so if there is indeed lead poisoning there would be concern for Zenith’s health, and they will watch for that.

Neither mother Redwood Queen nor Zenith are currently vaccinated for avian flu.  The fact that both Redwood Queen and Zenith seem to be healthy makes them think that avian flu is less likely to be the cause of Aurora’s death, but they will be watching Redwood Queen and Zenith for signs of illness, and both parents are now “at the top of the list” for trapping to be vaccinated.  28 out of 100 of the free-flying condors in the flock are currently vaccinated.  8 more have now received the first of two doses of vaccine in June and remain in isolation pens awaiting the second dose.  (Only adults that are not nesting and juveniles can be vaccinated, so it has not been possible until now to vaccinate Redwood Queen or Zenith this year, since they were nesting until now,)  Two more condors that were trapped recently were found to have high lead concentrations and have been taken to the Oakland Zoo for chelation treatment before they can be vaccinated.

One other potential cause for Aurora’s death that cannot ruled out is that s/he may have been attacked by a predator (even possibly by another condor) at night when Aurora was not visible on camera.”

Heidi will, no doubt, include this in her report. This attack reminds me of Ervie and his siblings after they fledged – out and out monstrous effort to keep the other away from the nest and food. Let us hope that neither is injured.

Heat. Dehydration. Lack of food.

‘J and PB’ called my attention to the report from FORE on Luna:

 “6/27/24 Update on Luna’s Necropsy & the effects of extreme heat on eaglets & other nesting birds. I contacted our Raptor Rescue Angel Marily Woodhouse from Defiance Canyon to get an update on Luna’s remains & she shared this important information with me…

“I emailed with the Lab, and she said on the 21st that she would be getting the body in the next few weeks, when someone from the Redding office is going to Rancho Cordova. Luna’s body is being kept frozen at the CA Dept of Fish & Wildlife Office until transport. Dehydration is an effect, but the initial cause is high heat and/or becoming too weakened to eat for that and additional reasons. All young birds grow incredibly fast, but eagles go from less than a quarter lb. to 8-10 lbs. in 10 weeks, which is a high level of physical stress. It’s difficult to keep up, even in optimal conditions. Extreme conditions exacerbate the stress. When I looked at the temperatures for the 10 days from June 5th to June 14th when Sol died, the average high this year was 101; in 2023 the average high for the same 10 days was only 88. An article in the Guardian today talks about the heat issues, focusing on people, who have more ability to escape than an un-flighted bird: 

“One degree celsius of warming may sound relatively small but it can translate into quite substantial impacts as it’s an average and the extremes of that average can cause much higher likelihoods of deaths from heatwaves, as well as agricultural impacts and wildfires,” she said.

Here is the article in The Guardian, FORE is referring to. We need to realise that heat and lack of food is going to kill so many, many more and that where possible we should provide supplementary fish:

In case you do not open files, here is the map. You will see that many of the problematic nests are within the upper heat reaches of 3 C.

It is the hard reality of our heating world and how terrible the impact is going to be on our beloved friends.

Oh, how lovely to see them. Larry and mate visit their Alcatraz scrape!

Look at that crop on Tuffy! Just saying…when food is plentiful.

Ferris Akel caught up with the Ns and with Big Red and Arthur on the Cornell Campus Thursday evening.

Big Red is moulting. She will be ‘Blondie’ soon.

‘H’ reports:
6/28 Colonial Beach had their third hatch overnight. 

6/27 Osoyoos osprey nest:  The live stream resumed at 0930.  It is not uncommon for Olsen to deliver three fish by that time of the morning, and when the cam went live, we could see a partial fish in the nest.  Soo fed meals from that piece of fish at 1007 and 1044, finally finishing the fish at 1057.  There were two more fish delivered that I saw.  A  large whole fish was delivered at 1513, that Soo fed for 11 minutes, and finally a bedtime snack fish at 1829.  Things are looking good for this bunch.

6/27 Forsythe osprey nest:  Due to Bigs dominance, Middle had not had very much to eat for a couple of days.  There were four fish delivered to the nest, including one from Opal.  The first fish of the day, at 0856, was a very large fish from Oscar, that Opal fed for 55 minutes.  Big was determined not to allow Middle to eat.  Despite the long meal, Middle was only able to eat 20 bites of fish!    Almost seven hours passed before Opal delivered the next fish at 1550.  It was a good size fish that she fed for 18 minutes.  Early on, Middle managed to position himself on the opposite side of Opal from Big, and Opal fed both of the siblings.  Sometimes, the moms will inexplicably move the fish, and blow the cover of the underdog osplet being fed to one side.  I was worried that Opal might do that…but she didn’t.  Middle ate for 18 minutes.  Middle was not able to get to Opal’s beak at the third meal consisting of a tiny fish.  At 1753 Oscar brought a fish that Opal fed for 13 minutes, and Middle was able to be fed on the opposite side from Big for 10 minutes.  One day at a time.

6/27 Fenwick Island osprey nest (Capt Mac’s Fish House):  There were six meals averaging about 12-15 minutes in duration.  This lil’ 13-day-old baby is growing, getting plump, and looking good.

6/27 Captiva Ospreys:  It has been an unusual, but successful season for Jack and Edie, and their two offspring.  Most of us always root for the underdog, youngest osplet.  Darling was younger by only 36 hours.  But, the siblings may as well have been three days apart in their ages, based on the degree of dominance from the older sibling, Ding.  Darling fought for his meals on an almost daily basis, including surviving a 3.5 day period of starvation.  Darling is a survivor.

Darling fledged on 6/26.  On 6/27 Darling flew back to the nest for the first time, and made a good landing.  Unfortunately, the fledgling Ding no longer wants to share the nest with him.  Ding acted very aggressively toward Darling for nearly half an hour, eventually forcing him off the nest. 

Ding’s instinct is simply one of survival.  Ding is not being ‘mean’.  She is a strong osprey, and that is a good thing to be.  Ding is territorial, and now only sees Darling as competition for food that a parent may bring to the nest.  Jack has been delivering five fish a day to the nest for Ding and Darling.  Today, Jack brought three fish to Ding at the nest.  Perhaps Jack took two fish to Darling on a branch.   That would be more fish than Darling would get after food fights with Ding on the nest. 

We were very glad to see Darling this morning.  We may or may not see Darling again on camera.  This is not an unprecedented turn of events at some raptor nests after fledging.  Jack will continue to bring fish to Darling away from the nest, Darling will learn how to fish, and he will continue to be a survivor.

Many thanks to the wise and capable Mods of the Captiva live stream, for assisting us with our thought processes on these events.

‘PB’ reports that Baby Cowlitz had 75 bites of fish Friday morning and is a survivor! How wonderful. It will live another day. Wish for fish! And gentle siblings.

Thank you so very much for being with me today. This was a hop skip and jump through some nests with some information on what is impacting our most loved birds. Take care of yourself. See you soon!
