Early Tuesday in Bird World

3 May 2022

News has come that the male at Denton Homes, Majestic Dad, has died. Avian Flu has been confirmed. The Denton Homes nest lost three eaglets and an adult male. The female, Majestic Mum, looks good on cam and is being monitored.

For those looking for information, here are two publications that have good solid information as well as some of the latest news on the spread.

This is one of the last images of E2, that sweet little eaglet off the MN-DNR nest that became a victim of siblicide at the age of 5 weeks. E2 hatched on 23 May and was shoved off the nest by E1 and subsequently euthanized on 30 April.

Dr Sharpe has been very busy. Another chick was to be banded on Santa Rosa Island and Dr Sharpe arrived just in time as the nest had collapsed and dropped. Here is that announcement

There are now five baby Peregrine Falcons in the Manchester, New Hampshire nest

Here is the link to that streaming camera (there are 2 of them).

There is an unease this morning on the UFlorida-Gainesville Osprey nest. I have observed fish being brought in but a bewildered adult and no feeding of the eaglets. An adult brought a fish on at 10:19 (or thereabouts). Both of the chicks began to scream for food. It was interesting watching what is happening. The adult eventually gave up and dropped the fish on the nest. Middle began to self-feed. You might have noticed him chewing on other bits of old fish and bones on the nest.

In the image below, the adult has brought in the fish. Middle is trying to get under here to be fed. (Big has the darker back plumage).

Middle anticipated that the adult would be feeding them and is trying to get to a point away from Big so that it gets some food.

The female places the fish in the middle of the nest leaving it. She did not feed the chicks when she brought in the piece of fish.

The chicks look on as the adult flies away. They do not understand what is going on – the same as me!

Middle begins to self-feed.

The chicks give up on the self-feeding. This picture was taken at 10:31.

At 10:47 an adult lands on the nest.

The adult, at first, appears to be a small piece of fish tail that they have brought in. Then the adult pulls part of a catfish – the head and part of the body – out of the nest. Both chicks are prey crying very loud. The adult appears confused as Middle tries to self feed. Is this Dad? and was it Dad earlier?

The adult looks completely bewildered.

Middle is attempting to self-feed. What is going on at this nest?

Middle had very little food yesterday and, if that were the case the day before, is not starving but getting there. It is clear that Big has no crop and is also hungry but not like Middle.

Middle may have gotten a little flesh off the open end.

While the dropping of the fish on the nest is a good strategy for both if there are two pieces and both chicks are self-feeding, it is clear that these two are not ready to feed themselves. Where is the female?

At 12 noon the adult returns, chicks crying desperately for food. The adult looks around. Is this Dad again? (From the behaviour I am assuming Dad). Where is Mum? If you observe the Mum feeding the chicks (or the dad) please send me a note. I cannot watch the nest all day today, unfortunately. I am quite concerned.

This has been posted on the UFlorida-Gainesville Osprey Nest page if you would like to help name the chicks, the adults, and the nest:

All I have to do is flip over to the Red-tail Hawk nest at Cornell and there is an instant smile. The four Ls do not have to worry about getting fed. Arthur is constantly bringing in food and Big Red feeds each beak until there is not one asking for food.

Larger clutch, direct feeding, lots of food on the nest, no history of siblicide – that is the difference at the Red-tail Hawk nest as compared with the UFlorida-Gainesville Osprey nest.

The West End nest of Thunder and Akecheta is an example of two parents working hard to make sure that each of their offspring survive —- and thrive! Both parents were active bringing in food. Several times they had tandem feedings. And look – Sky, Ahota, and Kanakini. They should all fledge and we hope return and raise their own families in the Channel Islands.

The Mum and Dad at Pittsburgh-Hayes consistently raise triplets to fledge. They hatched on 21, 22, and 25th of March making them 43, 42, and 39 days old.

These are Bald Eagle nests. Examples of siblicide that I listed yesterday include both Bald Eagles and Ospreys. It will be enlightening, at the end of the season, to compare data on species in terms of survival rates. It is also complicated and might not reveal a true picture in terms of prey availability, parenting, genetic predisposition to siblicide, etc. unfortunately. Another interesting comparison will be the rate of success of 3 clutch Ospreys in the UK with those in North America.

At the Hellgate Canyon nest of Iris in Missoula, Montana, the oldest osprey in the world laid her first egg of the 2022 season at 08:13.

Louis arrived a little later – fishless – to see the egg and do what Louis does.

I want to repost Dr Erick Greene’s letter about Iris’s relationship with Louis and why I should not be – nor you – upset with the fact that he has two nests. There is a huge change in the Osprey population that use the Clark Fork River for their food supply. Much of what Dr Greene says can also be applied to other species who are under pressure.

The Anacapa Falcons are doing well.

Things seem to have settled for now so that Bukachek and Betty can take care of their five eggs in the Mlade Buky White Stork nest in The Czech Republic. They have had disturbances – as recent as two days ago- from intruders like so many other nests this year.

It is a soaking morning on the Bald Eagle nest at Notre Dame University. There has been some strife at the nest with regard to the third hatch getting feed. It seems that there are good days and not so good. The weather might well impact feeding and behaviour today.

This is the history of this nest back to 2015: One chick, ND1 in 2015; ND2 in 2016; ND 3 and 4 in 2017; ND 5 and 6 in 2018, ND 7, 8, and 9 in 2019; ND 10, 11, and chick 12 who died on May 14 in 2020); ND 13 and 14 with a non-viable egg also in 2021. The hatches this year (2022) are ND 15, 16, and 17. Hopefully all three will make it.

Notice the turtle shells. James Broley commented that the Bald Eagles love turtle and he always found turtle shells in their nests when he went to band the chicks.

Wow! I just came across this Osprey nest at the US Steelworks Plant in Washington State.

It really helps to have metal workers when you need an upgrade. The original nest was on top of a light pole. Look carefully. In 2012, when a lighting upgrade was required, it was felt that a new nest platform should be constructed. The workers incorporated the old nest with the new metal one in hopes of attracting the birds to use it.

I do not know anything about the history of this Osprey nest. It is in Kalamana, Washington State and the Pacific Northwest had tremendous problems with the extreme summer heat causing many nests to fail. Chicks were leaping to their death to get away from the heat. So this is a warning if you start to watch this nest – there could be issues related to weather at this nest.

Eyases have hatched at the Cromer Peregrine Falcon scrape in the UK. The adults are Poppy and Henry.

The nest is on top of the Cromer Church Tower. In 2020, the resident pair fledged three chicks. In 2021, no viable eggs were laid. Now look at the little ones this year. Fantastic.

Here is a short video of their feeding. Notice how the female holds the prey.

Here is a link to the Cromer Peregrine Falcon page that has a link to the camera as well as lots of images and information.

And here is a link to the YouTube streaming cam for Cromer.

I am very interested in the White-tail Eagle nest at the Matsalu National Park in Estonia. Last year the couple hatched two chicks that perished from Avian Flu. It was the first recognized instance of H5N1 during spring breeding and marked a shift from the Avian Flu being prevalent in the fall and winter when it did not impact the breeding season. The two eagles have returned to the nest where WTE have been raised since the 1870s.

Will they lay eggs this season? If so, they are very, very late. In a normal season the eggs would be laid around the third week in March with hatching in late April. We are now 3 March.

This is the link to this nest in Estonia.

If you are watching the UFlorida-Gainesville Osprey nest today and see a feeding, if you do not mind sending me your observations I would be very grateful and would, of course, credit you for those! I am very worried about this nest. The female has to eat and it is possible that she is as ‘starving’ as Middle. Two fish on a nest is not enough to support the female plus two growing and demanding chicks. Thank you so much!

So many nests and so much happening – lots of good and much sadness recently. Thank you for joining me today. It is so nice having you here. Please take good care.

    Thank you Mary Ann for the update.
    I hope Iris will be able to connect with a mate other than Louis, but I am worried.
    Regarding the UFlorida-Gainesville osprey nest. I had not seen this nest since Little passed away. I checked today to see what happened and it appears that the mother was attacked by an adult osprey on the nest.
    12:57 p.m. (nesting time) – tussle with intruder.
    Fish arrived at 2:43 p.m. and feeding began. They both seemed to be eating. Good for them!

    1. Oh, thank you Akane for helping me today! I so appreciate it. Your time stamps really helped me go back and see what had happened. I was even able to find an image of Dad chasing the intruder away and everyone eating. It was so nice to see both of them being fed. I keep waiting to see if Louis might try and feed both females – Iris and Star – and the chicks. He would certainly win a lot of hearts if he did that for Iris.

        Glad I could help!
        I just checked and they were both food comas! Good, I am glad.

      2. Your help was really, really appreciated, Akane. Like you, I am going to bed not worried about them for today. Let us hope that intruder goes somewhere and enjoys itself and doesn’t bother the family again!

    Thanks Mary Ann for this info links and photos. I’m so sad to hear about the Florida nest and praying the Mom isn’t harmed and will return. 🙏
    So sad to hear that the Dad passed at Denton homes. Prayers for the Mom 🙏
    The little falcons look so cute and all the other nests too. I’m so Thankful and pray it stays that way.
    Have a nice afternoon and I look forward to hearing from you soon!
    Linda

    1. Hi Linda, She is home! She left at 15:30ish yesterday and returned today at 12;42 only to be attacked by the female intruder who came right into the nest in the morning and treated the chicks badly! Dad came in with fish and saved the day once things sort of calmed down and he had chased the intruder out. So it was a good day finally! Middle got a big feed. Thank goodness.
