Late Tuesday in Bird World

26 April 2022

It has been a great day in Bird World. When everything seemed so bleak with the ‘Only Baby’ at the Two Harbours nest on the Channel Islands holding on after a fall ten feet below the nest, the sun rose. When daylight came Dr Sharpe and two volunteers hiked for an hour to reach the nesting site. The trio rescued the eaglet, built up the walls of the nest, and placed the wee one back. Everyone held their breath hoping that the parents, twenty-four year old Chase and Cholyn, would appear immediately. They waited almost three hours to return. Everyone was on pins and needles. What if they did not return was the question on everyone’s mind. One did a fly by, and then they both arrived – Cholyn with some nesting material and Chase with the first fish of the afternoon. Baby was home! It was less than 24 hours but, it felt like an eternity. Would the eaglet be able to hold on? That strong brave little one stayed put until help came!

Dr Sharpe and the rescue were interviewed by ABC news:

“Oh, please, just one more bite,” Cholyn insists. Meanwhile, TH1’s crop is about to pop. Can you see it? The parents were overjoyed to have their chick back on the nest.

Cholyn and Big Red believe that no one should leave the table hungry. Tonight, squirrel was on the menu at the Red-tail Hawk nest in Ithaca, New York.

There are still three for Big Red and Arthur. As you can see, Arthur has really been packing the pantry and I am happy to say that most of it is squirrel and chippy.

There has been little mention of egg 4. It pipped and the chick was alive last night. It is difficult to tell because the other three Ls lay on it. If it is to hatch we should see that wee one in the morning. Personally, three eyases is great!!!!!! The three Ls appear quite healthy.

Liberty and Guardian’s eaglets for the 2022 season now have names. They are Sentry and Star. Well done everyone who took part in the voting for these two at their Redding, California aerie. Just look at them. Aren’t they gorgeous?

Spirit and Jackie shared a meal together today. It is hard to grasp but just look at the size of Spirit. They said that she would be the size of a Canada Goose now!

It is often hard to go back to a nest when the older siblings have been responsible for the death of the younger. It took me a long time to ‘get over’ being upset with Solly at the Port Lincoln Osprey nest when she caused the youngest, Tapps, to die at the age of 18 days due to starvation. It was only after she fledged that I warmed up to her again and I was honestly very sad when she died on an electrical pole in South Australia eating a fish. The two surviving ospreys at the University of Florida’s Gainesville Osprey nest are really doing well. The food competition appears to have dissipated. It is quite sad that the third hatch has to be sacrificed, or so it seems, for the good of the whole in terms of brood reduction.

The two eyases at the Presidio Red-tail Hawk nest in San Francisco are also eating well and growing without much of a problem. Once in awhile the eldest tries to be dominant but things seem to be alright.

It was sunny with wind gusts at the Two Harbours nest. Chase and Cholyn had to hover and approach the nest twice to land. It was dreary and windy just around the corner at the West End Eagle nest of Thunder and Akecheta. Of the three trips up the cliffs in less than two weeks, Dr Sharpe rescued the youngest male from the West End nest who had fallen and then returned a few days later to measure and band the three. It is easy to spot the big sister in the group now with her two little brothers.

On Thursday the 28th, the Ventana Wildlife Society is holding a Zoom-chat. It is free and it begins at 4pm Pacific Time. When you register you can submit questions to the staff. Because Condors eat carrion, I submitted questions related to the current Avian Flu in relation to those beautiful California Condors.

“California condor” by USFWS Pacific Southwest Region is marked with CC PDM 1.0.

Here is the link for registration, if you are interested:

In Latvia, the first egg at the Lesser Spotted Eagle nest has been laid. The nest is in a beautiful Spruce forest in Zemgale. The map below was posted on the English Forum, Looduskalender, and shows the area of the nest in green.

The nest is 17 metres off the floor of the forest and from its size, is believed to be at least five years years old. The couple are Anna and Andris. Lesser Spotted Eagles normally lay two eggs. If there is enough food available, both chicks will grow and fledge. If there is not, then siblicide will occur on the nest. It is good to understand this before you begin watching a Lesser Spotted Eagles nest (or a Greater or a Golden Eagle).

Andris is being shown the egg by Anna. Notice how small he is compared to the female in front.

Here is a short video of that first egg.

Here is the link to the streaming cam:

Do you love Iris, the oldest Osprey in the world? She is not only the Queen of the Ospreys but she is also one beautiful bird. Just look what good shape she is in after doing her winter migration. I am very impressed. I wonder what 28 or 29 Osprey years translates into human years??? or is there such a thing? I hope I look that good at the equivalent age!!!!!

Here is Iris this evening on her nest at Hellgate Canyon, Missoula, Montana.

Earlier, at 18:20 her mate, Louis, brings her the second fish of this season! For those who do not know Iris, Louis and Iris have this rather jaded bond. Louis also has a nest with Starr at the baseball park. This is the first year that I remember Louis bringing fish to Iris in several years. And now he has brought two! Wow.

Iris knows Louis is approaching and she does some quiet little fish calls.

Wow. That is a nice big fish. Notice the head is missing. Traditionally, males eat the head before delivering the fish to the nest.

Iris accepts Louis’s gift and flies over to the pole to eat it for her dinner. I wonder if we should be expecting eggs soon???

A marvellous book arrived in the post today. It is called Eagle Man and is about Charles Broley and his dedication to the Bald Eagle. Broley lived in Florida and in Canada. Broley was a banker; when he retired he devoted himself to bird watching. Broley became a world authority on the Bald Eagle. His observations taught us about courtship rituals, nesting, feeding, and even the migratory patterns of the eagles. I landed a copy in very good condition. It was obviously treasured by its owner, D. Gordon, who wrote on the flap that he received it in May of 1956. It is signed by Charles Broley. Inside the binding is the obituary of Broley who died on 7 May 1959 in Delta, Ontario. I am so looking forward to reading this book that inspired many to respect the Bald Eagles as many, like Dr Sharpe today, fought to bring their numbers up after most were wiped out by DDT.

Thank you for joining me. There are so many nests to cover and some will find themselves here tomorrow. Take care! See you soon.

Late Saturday and early Sunday in Bird World

23-24 April 2022

Everyone who watches streaming bird cams gets anxious at one time or another. The lives of our feathered friends are so fragile. There are so many factors that can trigger a significant change in their lives. Today I watched as Dad at the Denton Homes nest stood in bewilderment as his third chick was dying on the nest. He had just delivered a fish. I remember that same look of helplessness on the faces of the two White-tail eaglets in Estonia last year when their two chicks died of Avian Flu (confirmed by the Vet College there after retrieval of the bodies and the nest contents). They tried feeding them and they would not eat. I understand that the two adults left that nest and have not returned to it. Did they also die of Avian flu? or does their behaviour align itself with other raptors who have lost their chicks due to rodenticide, monofilament, etc. and choose not to use the nest again?

One of my readers, ‘B’ sent me an article from The New York Times on Avian Flu. Thank you! I am very grateful to ‘B’ for sending this to me. I have been so preoccupied that I have not had a chance to read the news as closely as I should.

This is a very good article on the Avian Flu. Please read it carefully. Dr Schuler, like the Cornell Bird Lab when I wrote them, is not suggesting people take down their bird feeders. She says, “So it doesn’t seem like that (bird feeders and songbirds) is a major source of potential transmissions”. Please read carefully.

Grieving is well documented in Corvids. In his book, The Emotional Lives of Animals, Marc Bekoff cites the case of a Magpie, a member of the Corvid group, being killed and lying on the side of the road. He addressed a mourning ritual whereby four Magpies stood over the deceased and gave it a gentle peck while two flew to get grass. Once they had covered the body the four stood vigil for a period of time and then flew away. The covering ritual has been observed by so many of us when an eaglet dies. We saw this with Connie and Joe at Captiva, at the White-tail eagle nest in Estonia, and in a variety of other nests.

The parents at the Denton Homes nest appear to be in a state of shock and mourning. Saturday morning when the three chicks died, the Dad was bewildered. Later, Mum came and incubated the trio before their bodies were moved to the rim of the nest. Tonight, one of the adults is standing vigil over their bodies. It is both moving and sad.

The wee chicks look like they are sleeping.

The Mum has come to the nest. It is a wet dreary day to keep her babies warm. She must feel confused and helpless. Yesterday there were three vibrant nestlings and they were dad when Dad brought in prey.

Late in the day the parent stood vigil over the nestlings and the nest.

Avian Flu is killing many wild birds throughout the United States and Canada. Nestlings are particularly vulnerable since they are tiny and the flu kills them quickly (the only blessing). It is hoped that the parents do not suffer and survive it.

Another, ‘W’ sent me an article on the impact of the wind turbines on birds. It comes from the Audubon Magazine. Thank you ‘WW’.

I have checked on the UFlorida-Gainesville Osprey nest. That miracle fish did arrive at 18:32:45. Little Bit did what he could do to try and get even one bite. The fish was finished at 19:11:16. It has now been more than 72 hours since Little Bit had more than 5 bites of food. He was brutally attacked by Big and I do mean brutally.

In the image below the fish has just come to the nest. Big has already attacked Little Bit for walking up and trying to get a bite. Big frantically waves his wings going back and forth from Little Bit to Middle. Middle is trying to stay away and is scurrying around the nest to get some fish from the other side.

Big is pulling the skin and has plucked a part of Little Bit. He is shaking it frantically back and forth, up and down.

The abuse has been extreme with some plucking, pulling and twisting of the loose skin on the wee one’s body. I do not need to say anymore. This is the last fish on this nest today. Little Bit is already starving. By morning the two older will be famished. I am desperately sad and feeling helpless about what is happening on this nest. It began so beautifully. I am at the point where I wish for Little Bit’s suffering to end. That would be kind.

Little Bit was alive when a fish came on the nest around 10:15 Sunday morning. He tried to get some fish. It is now raining. I believe he died at 11:39. This poor little one. All Little Bit wanted was some fish, not a lot – just a little. He had walked up to the mother fish crying when the other two finished eating but no fish. He walked as far as he could and laid his little head down. No more pain, no more suffering. Brave Little Bit.

UPDATE: LITTLE BIT MOVED ITS HEAD BUT IT IS WEAK.

It is best never to cheer or wish for three birds on nests. It is inevitably difficult and many perish starving to death while at the same time enduring beaking just because they are there.

Moving to a happier nest. It is late Saturday at the nest of Big Red and Arthur, L2 is just about here!

You can see that the shell is now just on half of L2. Big Red is doing her rolling trick to try and ease the shell off without harming her baby.

How cute! Two little fluffy ‘snowbirds’ in the morning. L3 is pecking away!

Big Red likes to do everything. This is the 5th season for her and Arthur and she has not taken a real break during hatching!!!!! Arthur has been busy filling up the pantry adding chippies and squirrels.

Little sleepy head. So cute.

At the Captiva nest, Little or MiniO has still not returned. Jack has brought in a big fish and Middle or Little is enjoying it. There is much discussion on the chat because Andy has not brought in another fish and Lena has not eaten. When the chicks fledge the male is responsible – for millions of years of imprinting and doing – for the chicks to be fed. He is providing for the fledged chick on the nest. Lena has finished her job of raising and feeding the chicks. She will begin to go fishing for herself. There is no word about Little or MiniO. We do not know if Andy is providing fish to her elsewhere.

It has been a morning – full of sadness and, at the same time, blessed relief for Little Bit. Sadness about the H5N1 racing through some of the waterfowl and raptors and happiness at the successful hatch of L2 and the pip of L3. I will be checking on the rest of the nests late today. Surely there will be lots of good news! I understand that Spirit is now the size of a Canada Goose! Keep that imagine in your mind as you watch a short pick me up video. My friend ‘R’ sent me a short clip of Canada Geese, waterfalls and spring to cheer me up this morning. As I look out on the snow, I am so grateful. Thank you ‘R’. I want to share it with you! [Note: It is the waterfalls, not the movie and not the ad.]. Time to feed the garden animals!
