Good Morning Everyone,
We are within a fortnight of Ospreys potentially arriving home from their winter grounds to their spring/summer breeding sites. I get ‘Osprey’ fever. Suddenly, you will think that eagles have vanished from the face of the earth as this post gets taken over by the ‘fish hawks’. I will continue to report on the eagles and, as we know, falcon and hawk season will begin also. I will, however, be watching closely for all osprey arrivals and eggs laid. Last year ‘H’ and I monitored over 300 osprey eggs from the time they were laid through fledge and migration. It is daunting and we hope to add more nests this year. You can help!
We do not have all of the European nests in our data system. If you are fans of a particular nest in Germany, Switzerland, Italy, Spain, etc., please do send me the name, a link to the streaming camera, the names of the adults, the date of their arrival, dates for eggs laid, hatch, and fledge. The more eggs and chicks monitored the better the data. My long term study is on siblicide, but I am now including mitigating factors leading to siblicide and other causes of death to the osplets. Last year there was the Nor’easter in the US, overfishing of the Menhaden, and in the UK much predation by other raptors. That also happened in the US. Do not be shy. I am very grateful for all the eyes on the nests and information.
If you see an osprey nest and are concerned that siblicide is taking place and I have not mentioned it in my post, please do let me know. You can do this through the comments or by sending me an e-mail: maryannsteggles@icloud.com
Thanks so much!
Tim Mackrill, Director of the Roy Dennis Wildlife Foundation, has been talking about his new book, The Osprey. There is much about migration because that was the focus of Mackrill’s PhD at the University of Leicester (yeah – my alma mater!). It is a really good listen and you will learn a lot so, even before we get to Jackie and Shadow, here is the link to that Zoom presentation. I promise you will thank me after you listen to all of it!
Waiting. We are waiting for a storm to hit, but we don’t know if it will actually happen. Meanwhile, the big storm that is going through the area around Big Bear appears to be worse north of Jackie and Shadow. Still, I know that we all worry about them. There are three eggs. The first was laid on the 25th of January. So how do you count? Is it six days in January, 29 in February and now three in March. If so, the first egg is now 38 days old which is right in the frame of 38-39 days for Jackie’s historical hatches. The third egg is 33 days old. The couple have been so diligent, so careful, so dedicated to this clutch. Please let one of them hatch and be a perfect little eaglet.

Jackie and Shadow continue to make the news: CBS evening news with Nora O’Donnell. Thanks, ‘R’
I didn’t know it. ‘B’ wrote and directed me to BENSWEATHER.com This will give you a better forecast for Jackie and Shadow’s nest.

It continues to be miserable. I really do not like it when the weather is wet and cold and there are little ones. These eggs can wait a few days, OK!

Richmond was waiting for her and preparing the nest. Rosie arrived Saturday morning at 0713. Relief.

The first one was stuck to a shell and feared lost. The second unzipped its egg in what felt like record time. Now both of them are the cutest little bobbleheads! Duke Farms aka Dukies.



One of the first feedings for both eaglets at Duke Farms.
Should we call it ‘Spike’? One of the Johnson City eaglets.

Indeed, my stomach sank several times today because of the Johnson City eaglets. I knew there were two. I could only ever see the one trying to be a Tyrannosaurus Rex. Finally there was the second head.





There’s another one with a long neck or as ‘J’ says, ‘A Nessie’. This time at Superbeaks.

Meadow goes under Abby to eat! Declares it a ‘no bonking zone’ from Swampy.




Ron and Rose are still feeding R6, their ‘big’ baby.




There were several fish species delivered to Cal at the Captiva Bald Eagle nest on Saturday. They included a Tilapia, a Sheepshead, and a Striped Mullet. Cal likes to be fed, too! That Sheepshead looks yummy. Cal can also self-feed much better than R6.

Two immature Bald Eagles have visited the Dulles-Greenway nest that belonged to Rosa and Martin and then Rosa and Lewis (part of one season only). Could these by Rosa and Martin’s fledglings returned older? I would love to think that one of their offspring would take over their nest like Samson did with his parents, Romeo and Juliette, at NE Florida.

Did you know that California Condors rarely nest two years in a row? Kinda like the Royal Albatross. Well, that might change this year.

Why are condors important to the environment? Remember, I promised to slowly introduce you to these amazing carrion eats. See if you can make a list before peeking below! Don’t look.
The US National Park Service says, “
Indicators of Wildland Health
In addition to keeping wild landscapes clean, California condors are also good indicators of the ecological health of wildlands and ranchlands. Condors are very long-lived birds and they reproduce slowly, averaging successfully fledged young every two years. Condors can fly many miles in a day in search of food. They are also sensitive to certain toxins (like spent lead ammunition), and nestlings are at risk from ingestion of garbage (like small bits of microtrash). Because of their far-ranging movements, longevity, slow reproduction, and sensitivity to toxins and pollution, condors are strong indicators of ecological health on the open landscapes they inhabit.
As members of a high-profile endangered species, condors serve as the proverbial “canaries in a coal mine,” drawing attention to toxins and pollutants that affect many other species of birds, mammals, and wildlife. Promoting condor recovery also supports wildland health and vibrant wildlife populations in general.”
Another article on what is causing the gorgeous Rainbow Lorikeets to become paralysed.
They are one of the most rare birds in the world. They live a perilous life. How can you help the California Condor? Audubon California gives you some ideas. If you live close, you could volunteer. You can also donate and you can also advocate on their behalf. If you decide to donate at some time, please provide your funds to the Ventana Wildlife Society. You can go to their website and see the amazing work that they do on behalf of these amazing birds in Pinnacles and Big Sur.
Calypso, the 2019 fledgling from the Port Lincoln Osprey barge. First believed to be a female has now been determined by behaviour to be a male.

Ferris State University will have its osprey cam up and running before the birds arrive.

It’s to Murphy the Bald Eagle incubating a rock and then getting an eaglet to raise. No, it is Hinkley, the Vulture, who is nesting with rubber duckies at the World Bird Sanctuary. So cute.

Lena continues to want to bond and is preparing the scrape on the cliffs of Anacapa.
For those of you waiting for Angel’s cam to go live, it is!

And last, but never least, Big Red. She spent a lot of time at her nest on the Cornell Campus on Saturday. Some of us were holding our breath thinking it would be the earliest egg laid by this 21 year old Red-tail Hawk. And then she left! Lookin’ good. For those of you that are not familiar with Red-tail hawks, just look at that tail and you can see why they got their name.
