Monday in Bird World

17 February 2025

Good Morning Everyone,

We hope that each of you has had a lovely week and an even nicer weekend if you are still out in the workforce. We are so happy that you can be with us today. It is -31 C, and we have been in another extreme cold warning area for several days. Fortunately, the conservatory is on the south of the house, and the sun heats it regardless. The Girls just have to be out there watching their garden friends! It is, however, difficult at times to get outside and we often find ourselves thinking of the warm sun and birds in Guadeloupe.

This is the last day for the Big Bird Count. You have until 1 March to get your submissions into Cornell. Our garden bird numbers were down due to the extreme cold.

The deer have been eating the twigs off the newly cut trees in the park. Wood twigs are definitely not full of nutrition. I have not seen any deer in our garden for a few weeks.

This tiny little one is such a sweetie.

The temperatures continue to be on the ‘cold’ side. We keep the conservatory open for The Girls so they can enjoy the squirrels and the birds – and us, too. It will be so nice when April arrives – two months to go – until we thaw out. Star and Brock continue to come to the feeder, but I have seen no other cats which is really a blessing.

Hope and Calico are never far from one another. It is so endearing.

Hugo Yugo was grumpy at me for waking her up to try and get a photo!

Missey was grouchy too!!!!!!!!

The Girls seem to have almost gone into hibernation preferring to sleep during the cold months instead of even eating. They play with one another starting around 2130, but during the day, it is strictly nap time. Oh, what a charmed life they lead.

We hope that the bi-weekly posting is working out for you. I want to try and pick a topic that brings some additional information – that is more educational – than just a listing of what is happening at the nests. This change is allowing me to do that!

So today, I want to look at the world’s most beloved Bald Eagle couple, Jackie and Shadow, whose nest at Big Bear and its elevation can be causing the issues relating to their eggs not hatching. In addition to the information below, I am also including some other information on the DDT that was sprayed in the area that might well be contributing to the thickness (or lack thereof) in some of their past egg shells. Even thought DDT spraying was outlawed decades ago, the soil remains contaminated and still impacts wildlife including Bald Eagles.

So why do Jackie and Shadow struggle with their eggs at such a high altitude? Their nest is 7000 feet above sea level and is known to be one of North America’s highest Bald Eagle nests. When I sought an answer, my computer came up with this one generated by AI. It looks reasonably thorough and should help us understand this couple’s difficulties in hatching eaglets. That said, we know that on occasion, they do have success. In 2023, more than 45 inches of snow fell on Jackie and Shadow’s nest due to the atmospheric rivers that year.

Eagles nesting at high altitudes can experience difficulties with fertility and egg hatching primarily due to the harsh environmental conditions at those elevations, including: lower oxygen levels, extreme temperature fluctuations, strong winds, and limited food availability, which can all negatively impact the development of the embryo within the egg and the overall health of the breeding pair. 

Key factors contributing to this issue:

• Oxygen stress:Reduced oxygen levels at high altitudes can affect the egg development process, potentially hindering the embryo’s ability to properly grow and mature. 
• Temperature extremes:High altitude environments can experience significant temperature swings, making it challenging for the female eagle to maintain a consistent incubation temperature needed for successful hatching. 
• Weather challenges:High winds and storms at high altitudes can disrupt nesting activities, potentially damaging eggs or causing the adults to abandon the nest. 
• Food scarcity:Finding enough food to sustain both the breeding pair and their chicks can be difficult in high altitude habitats, especially during harsh weather conditions, leading to malnutrition and impacting fertility. 
• Hormonal disruptions:Environmental stress at high altitudes could potentially disrupt the hormonal balance of the eagles, affecting their reproductive capabilities. 

Here is more information on this nest:

The nest of Jackie and Shadow, the bald eagles in Big Bear Valley, California, is about 7,000 feet above sea level. The nest is located in a Jeffrey pine tree that’s 145 feet above the ground. 

Explanation

• The nest is one of the highest known bald eagle nests in the United States. 
• The nest is located in the San Bernardino National Forest. 
• The nest is home to Jackie and Shadow, the only year-round resident bald eagles in Big Bear. 
• The nest is monitored by a live-streaming camera operated by Friends of Big Bear Valley, a nonprofit environmental preservation group. 
• The nest has grown to be over five feet wide and six feet deep. 
• The nest was started near the top of the tree by the previous resident pair, Lucy and Ricky, in 2012. 

The nest is located on an undeveloped parcel of land on the north shore of Big Bear Lake. 

Did you know that Jackie is thought to be the offspring of Ricky and Lucy? That would mean that she is now thirteen years old in 2025. She is the first eaglet to have ever hatched at the Big Bear nest in 2012. In recent years, her and Shadow have laid at least fourteen eggs together with five of them hatching. Simba fledged in 2019 and Spirit fledged in 2022. I still remember that fantastic eaglet. I am sure you do, too. Other eaglets were ZJ1 (yes, he was banded) named Cookie, who died of hypothermia during a storm in 2019 and Stormy, who fledged in 2018. Now, what was the name of the other one? Would you happen to know?

There is nearly a 33% chance that an egg will hatch. So will one of the three eggs hatch this year? We must wait to see. Maybe all three will! Clearly Jackie and Shadow with their devotion and love for one another and the determination they have to raise an eaglet offers each of us hope and inspiration.

Pip watch begins for Jackie and Shadow on 1 March – well now, let’s count the days from today: 12!!!!!!!! We will be on pins and needles with excitement.

The Ravens wished to give Jackie grief. She wasn’t having it.https://youtu.be/_-zcJ-1qwAk?

Looking at the other nests:

Kistachie National Forest, E3: They are the cuties little fat bottomed eaglets. Their Mum, Andria II, is doing a fantastic job keeping both eaglets well fed.

John Bunker Sands Wetlands: Dad brings in a whopper of a fish for Mum and the kids!!!!! (Thanks MP)

Fraser Point: Andor and Cruz have their first egg of the 2025 breeding season.

Abu Dhabi Osprey Nest: The triplets being raised by the lone female and two males were banded. Heidi caught the action on video.

The average temperature in Abu Dhabi is 25 degrees C. Last year it was 30 C. There is no temperature for the nest which is located on a huge mound of sticks on the desert. The chicks survived with lots of fish!

West End Nest: The camera was down on Friday for awhile due to a big storm that went through the area. They played highlights. Hearts were broken everywhere watching Akecheta feed his triplets.

Sauces: Jak and Audacity’s first egg is still holding! The other two have broken. Well, we only need one and this couple sure deserve it. Their issue is, of course, not the same as Jackie and Shadow and the higher elevation nest. Theirs is strictly due to the DDT in the area. Next posting will look at why some nests in the Channel Islands might be

Two Harbours: Chase and Cholyn are working on their nest. No eggs yet.

USS Steel: The first egg for Irv and his new mate, Stella, arrived and the second was laid on the 16th. Congratulations to Irvine and Stella. Missing Claire. https://youtu.be/hg37rCwNavc?

Decorah North: Second egg laid on Valentine’s Day. First egg laid on the 11th. (In 2024, the first egg was laid on the 15th of February). Oh, we are going to be busy in five weeks time with all these hatches!

Trempealeau Bald Eagle Nest: There is some concern that Mr T has not been seen at the nest since the 11th of February.

FOLFAN: Second egg laid on the 13th of February.

Hilton Head Bald Eagles: George and Gracie’s oldest gets out of the egg cup! https://youtu.be/2zmRnrAIbfw?

NE Florida: NE 31 stood on its feet, flatly on the nest, on Saturday the 15th for the first time. A milestone. What a great eaglet. Huge crop. Devoted parents. Melts your heart just watching Gabby and Beau care for this precious one.

‘A’ comments: “The chatters are calling it NE31’s stick fort, but as I described yesterday I think it was, there are some very thick kiddy rails on the side of the nest opposite the dining table. NE31 has been sleeping so that one of those large sticks is across his back, so that I am hoping his stick fort might make it hard for an owl to get a grip on him and extract him from under his stick. Again tonight, alone on the nest, he was sleeping in his stick fort when Gabby came down to the nest around 1.42am. She aerates the nest, in the process extricating NE31 from beneath his stick, and NE31 stands up tall and eyeballs mum, then tries to burrow back under the stick fort. 

Gabby has some difficulty brooding NE31 because of the stick but eventually the eaglet snuggles down in front of her breast feathers and goes back to sleep. Mum leaves again at 01:55. Little now can no longer get under its stick fort. The stick has been broken and displaced so that it no longer affords the protection it has done to the point. Unfortunate. 

Beau arrives on the nest to check on NE31 at 03:03:35 and does some aerating of the nest. This eventually disturbs the sleeping NE31, who stands up tall and bonks dad! (TS 03:12:25). TOO funny. It’s hard to see how effectively the stick fort now protects NE31 – it may represent some form of obstacle still, though not as useful a barrier as it was two nights ago, before it got broken. 

It is reassuring to me to see Beau on the nest tonight. It is a little early – I hope he remains until daylight because we know how that hour or 90 minutes before the sky begins to lighten is very much the favourite time for owls to hunt – or so I have observed when watching GHO cams. “

SW Florida: M15 is thinking he would like another chance at raising eaglets this year. How is F23 feeling about that? https://youtu.be/ol57dhBfdbg?

NCTC Nest: Scout is delivering fish dinners and grasses to Bella. https://youtu.be/MBaiPt014YU?

No wonder. Bella laid her third egg!!!!!!! Scout is really going to be a busy lad if these three eggs hatch. https://youtu.be/S4DH20KLU30?

Cardinal Land Conservancy: Bonnie and Clyde have their first egg and by the time you read this they should have their second.

Dade County home to Ron and Rose saw the ringing of R7 and R8.

Captiva: Connie and Clive’s Dasher and Dancer work their wings on the nest hoping to fly like Mum and Dad. https://youtu.be/-h0DY3y8MoA?

Centreport: Waiting for the first egg.

Moorings Park: Harry and Sally are incubating three eggs!

Achieva Credit Union: Jack and a new mate ??? – no eggs yet.

Kauai Moli:

Royal Cam Chick Royal Albatross Colony, NZ: Some really cute close ups. https://youtu.be/NVeCGfehAfo?

Leucistic Red Tail Hawk Nest: ‘A’ notes with concern: “The last visit to the nest was on 2 December – I think there is an entry in the log noting that Angel had flown under the nest (twice) about a week ago, but it is starting to look like this season will be much like last. We may not see them again this year. It is a mystery – where are they going? What are they doing? And why?”

The hawks might have relocated like they did last year, but we know that they are fine.

World Bird Sanctuary. This falls in line with the story below about the turtle where wildlife manage to survive under very challenging conditions. This one with a severe beak injury.

Wildlife Haven, Manitoba, Canada: Dr Tess designed a ‘contraption’ to help a turtle whose shell was soft and sunken in the hope of giving it a second chance at life. I love this vet and wish she would be here forever. She doesn’t give up and as I have said several times, she has no trouble believing a three legged deer can survive or a one legged eagle. Bravo, Dr Tess!

Calico’s Tip for the Day: If we want to help wildlife, modify the amount of beef, palm oil (please do check your labels), and timber. Trees are cut down for these crops and there are clear alternatives!!!!!!!!! Calico also recognises that birds flourish when coffee is grown in the shade. Why not reduce the amount of coffee you drink in order to help wildlife? Look for the certified Birds and Beans coffee!!!!!!!! Accept no substitute. Indeed, I can tell you that having one good cup of coffee that I know did not cause a tree to be cut is much better than drinking 3 or 4. Try it.

Killed for sport and dumped. It is time to end this archaic practice in the UK.

Thank you so much for being with me. Please take care. See you on Thursday. Have a great week everyone. Sending you good positive energy.
