Update: WTEs in the region of Dillingen (alluvial forests), Germany - both have successfully fledged:

Quote: "Young white-tailed eagles circle in the sky

But then Harald Böck suddenly winces, he has heard something. "Pscht, quietly," says the bird expert, putting his hand to his ear. "It could also have been a black woodpecker, they call something like that," he says and enthuses: "There are seven species of woodpecker here in the alluvial forest, collared flycatchers, and then a jay calls."

The alluvial forest offers ideal living conditions for many bird species. But then the call sounds again, now he's sure it was a white-tailed eagle. And then forester Martin Eggert points to the sky: "There's one! And there's the second!" Far away, but still easy to see thanks to its large wings, first one chick flies, then the second. They seem to be playing with each other, flying apart and back together again. A wonderful spectacle in the blue summer sky. The ornithologists are enthusiastic, so they have not yet seen the two in action. "I've also only been to the eyrie once since they were born," says biodiversity consultant Julia Heidtke from the Dillinger district office. "We wanted to disturb the animals as little as possible."

One of the oldest pairs of White Tailed Eagles - in Scotland. Frisa is said to be crispy 30 years old, not 38, as stated earlier above:

Quote: "The UK’s oldest known white-tailed eagle pair have celebrated their silver anniversary by successfully fledging their 25th chick.
Skye, who is now 28, and Frisa, who is 30, live on Mull and first paired up in 1997 before having their first chick the following year.
The pair’s newest chick – thought to be a female – is the latest in a white-tailed eagle dynasty. "

Bird flu threatening WTE population on the Isle of Mull:

Quote:
Mull white-tailed eagle chick dead from bird flu

"Concerns are growing over the impact highly pathogenic avian influenza HPAI, also known as bird flu, might have on Scotland’s iconic white-tailed eagle population after a dead chick on Mull tested positive for the disease. Over the last few weeks, chicks from at least four white-tailed eagle nests on the island have either died on the nest shortly before or after fledging, with the parent birds’ behaviour consistent with the chicks having died."

RE: WTEs in UK - Isle of Wight G466, Oct 07-2022

https://www.roydennis.org/2022/10/07/returning-home-2/

Quote: "The satellite tracking work that we have undertaken during the first three years of the Isle of Wight project, which we run in partnership with Forestry England, has provided a fascinating insight into the dispersal of young White-tailed Eagles. This has shown that many of the young birds explore widely in their early years before returning to the South Coast as they approach breeding age. (...) Having spent five months in northern Scotland, G466 began heading south again on 22nd September, and this time with real purpose, arriving on the South Coast on 28th September and the Isle of Wight the next morning, having flown 1003km in seven days.

The Isle of Wight WTEs prove to be really amazing. Latest tagged male to return is G463.
Quote: "During his 27-month period away – the longest of any of the released eagles so far – he flew over 17,000km and visited seven different countries."

And most of it with one leg. Quote: "One of the places G463 re-visited during his second visit to mainland Europe, was the Biesbosch, a large wetland in the Netherlands which supports breeding White-tailed Eagle and Osprey. Whilst G463 was there we received images taken by a local photographer, kindly sent to us by Dirk van Straalen who monitors White-tailed Eagles in the Netherlands. We were very concerned that the photos clearly showed the bird was missing his right leg below the knee. We initially suspected that this was a recent injury, but when we analysed the satellite data it was clear that G463 had been behaving apparently normally for several months; indicating it probably occurred earlier."

I admire such shots that are so perfect that it can hardly have been a coincidence.
Very happy and important documentary moments...

A sparrow, which I saw last summer - fluffy, young .... the left wing was clearly malpositioned also eats at my aviary. He stands up but hangs at the same time. I didn't give the guy long...

To this day he is completely okay and a daily visitor! :2thumbsup:

No support for decreased reproduction with a population increase in the White-tailed Eagle"
