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

https://www.br.de/nachrichten/bayern/se ... se,TEE2U5w
GT: https://www-br-de.translate.goog/nachri ... r_pto=wapp

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:
https://news.stv.tv/highlands-islands/w ... 25th-chick

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:
https://www.rspb.org.uk/about-the-rspb/ ... -bird-flu/
Quote:
Mull white-tailed eagle chick dead from bird flu
Jess Barrett
@RSPBScotland
Thursday 25 August 2022
"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:

two adult white-tailed sea eagles were found dead floating on water close to each other on Maisaari island in Rymättylä near Turku on April 15 2023. one of them had Estonian rings with letter K, which means that it was ringed in 1999.
https://www.ts.fi/uutiset/5967599

the case was notified to police as the eagles seemed to have injuries which were possibly caused by shooting. the corpses were sent for examination to Ruokavirasto (Finnish food authority) which is the Finnish authority responsible for this kind of work (as well as for example analyzing samples of possible bird flu).

on May 10 Ruokavirasto reported their results. they had found no signs of shooting in the birds: no penetrating wounds and no signs of bullets or metal fragments were found. the imminent cause of death of other bird was drowning, and the other had died of a sudden failure of the heart and cardiovascular system (shock). both were females. they had most likely had a territorial fight and died as a result of that.

shocking news from Åland Islands:
permits to shoot 5 white-tailed sea eagles at Långskär island have been granted by the provincial government of Åland.
Långskär is a large breeding island of common eiders (Somateria mollissima) with about 1000 eiders. the common eider has lately become a highly threatened species like the eagles used to be some 50 years ago.
locals claim that tens of sea eagles gather on the Långskär breeding colony to harvest the brooding eiders who have their nests on the ground under the open sky.
https://www.hs.fi/kotimaa/art-2000009580563.html

spring hunting of male eiders has been allowed in Åland islands although it is against the EU directives. the eider population has become highly imbalanced: there are many males for one female. this is due to the high mortality of females during the brooding time.

In Germany, at the Naturpark Nossentiner/Schwinzer Heide, this season's WTEs have been ringed recently, s. here:
https://www.wir-sind-mueritzer.de/allge ... n-beringt/

Quote, GT: "This year's white-tailed eagle chicks were recently ringed. A team of specialists led by Dr. Oliver Krone from the Leibniz Institute for Zoo and Wildlife Research (IZW) in Berlin in the nature park. The nests were checked together with nest supervisor and ranger Frank Hänsel. Sea eagles usually have one or two young. Exceptionally, an nest with three young was also found this year."

- Nice pics.! :D

White tailed eagle stops car – driver in clinic- eagle is dead
In the north-east of Germany - especially on the Müritz - there are many white-tailed eagles and ospreys. One of the birds of prey caused a rare accident on Autobahn 19 between Wittstock and Röbel, in which a driver was injured.

As "We are Müritzer" learned from the police in Neuruppin, a 36-year-old driver collided with the sea eagle near Wittstock a few days ago. The eagle smashed through the windshield. A splinter flew into the driver's eye, so he had to be taken to a hospital. The man was heading towards Berlin.

The car was no longer drivable. The damage was estimated at at least 5000 euros. The car was towed.

The white-tailed eagle did not survive the accident and had to be disposed of by the public order office. The police could not say why the large bird of prey was traveling so close to the freeway. Sometimes eagles stay near roads because they find carrion or dead animals to eat there.
https://www.wir-sind-mueritzer.de/allge ... in-klinik/

BTW: The Mecklenburg Lake District is one of the most densely populated breeding regions of white-tailed eagles and ospreys in Germany. The police warn that the large birds often stay on roads to eat game or carrion that has been hit.

That's why I never drive very fast on this circuit. Many buzzards, kites are also killed. I don't even want to talk about all the mammals. there are a lot of dead birds and animals on the route Rostock Berlin and back..

First WTE in 240 years fledges in England, s.here:

https://www.roydennis.org/2023/07/18/fi ... n-england/

Quote: "Steve Egerton-Read, White-Tailed Eagle Project Officer for Forestry England, said:

“We are thrilled that this moment has happened and at such an early stage in the project. At only three years old, it is remarkable that the pair have successfully bred, with most white-tailed eagles not attempting to do so until they are at least four or five. This pairs’ ability to breed and fledge their chick at this early age is extremely encouraging.”

“It is really hard to put into words just what an incredible moment this is for the return of these iconic birds to England. It is evidence of just how well the eagles are starting to fit back into this landscape and how, with a little help, nature can begin to return and thrive. Although it has not been possible to set up a public viewing site at this location, we are hopeful that one of the other pairs that has become established in southern England will choose to nest in a location that we can share with the public in future years.”

Two white-tailed eagles released into the wild in the Plön district
Status: 08/11/2023 3:57 p.m
Two white-tailed eagles have been nursed back to health in the bird sanctuary at Eekholt Wildlife Park over the past few months. The two animals were released into the wild near Plön on Friday morning.

Within a few minutes, the two three-kilogram eagles flew back to freedom one after the other in the Rixdorf forest district (Ploen district). The young birds had fallen out of their nests during the breeding season and would not have survived without human care, according to the manager of the wildlife park Eekholt (District Segeberg). The project group for the protection of white-tailed eagles now counts 99 breeding pairs of white-tailed eagles in Schleswig-Holstein. Most of them live in the districts of Plön and Ostholstein. According to the project group, this is a positive development. Schleswig-Holstein still offers enough habitats for the white-tailed eagle. Because the Geest and west coast areas are also increasingly populated by birds.

Before they were released, the two white-tailed eagles were ringed - a procedure that has been carried out in Schleswig-Holstein since 1976, according to the sea eagle protection project group. According to this, 34 young white-tailed eagles were ringed in their nests this year alone. In this way you get insights into the life paths, reproduction, or the causes of death of the animals, explains the project group: "For example, a dead ringed white-tailed eagle was found on Lake Hostrup in Denmark in 2021, which in 1993 was found in an eyrie in Schleswig-Holstein This white-tailed eagle lived to be 28 years old and has contributed to the re-establishment of the species in the formerly deserted region of Denmark."

Rescued white-tailed eagle flies over SH with GPS transmitter
Status: 05/06/2022 1:09 p.m


White-tailed eagle "Taipa" again circles over the waters and fields in the north of Schleswig-Holstein. The club sea eagle protection Schlei from Sönderby in the municipality of Rieseby (Rendsburg-Eckernförde district) nursed the animal and released it.

When "Taipa" was found with a broken wing in August last year, his chances of survival were initially not very high, reports the sea eagle protection association. However, the association and Christian Erdmann from the wildlife and species protection center in Klein Offenseth-Sparrieshoop (Pinneberg district) took care of it, raised donations - and found veterinarians who operated the eagle.

On the go with a GPS transmitter
"Taipa" should now be quickly released back into the wild - with a GPS transmitter. Because those responsible wanted to implement the first telemetry project with a white-tailed eagle in Schleswig-Holstein. The station's costs, at least 1,400 euros, came from donations. "Now 'Taipa' has been equipped with the GPS transmitter and from now on we can see where he is currently and whether he is moving. We found a project partner in Ulrich Voigt from the University of Veterinary Medicine in Hanover. An additional white-tailed eagle is also accepted take part in the telemetry project," writes the Seeadlerschutz association in a statement. The data should later provide information about the flight routes of the white-tailed eagle - especially with regard to existing and planned wind farms.

More routes every day
After those responsible released "Taipa" on a meadow on the Koseler Au, including the GPS transmitter, the eagle "obviously didn't really want to believe in his freedom yet. But he covered longer distances from day to day and slept safely in tall trees," writes the club.

The association does not reveal exactly where the animal is currently located, because white-tailed eagles have many enemies among humans. Just this much: the GPS transmitter is transmitting, "Taipa" seems to be doing well - and "if everything continues to go well, we will receive a location and movement record via the attached transmitter every hour for three to five years."

...because white-tailed eagles have many enemies among humans.
For this:
Ein streng geschützter Seeadler ist im münsterländischen Naturschutzgebiet Letter Bruch bei Coesfeld erschossen und geköpft worden. Klauen und Kopf des Tieres wurden nach dem Tod entfernt.

Man habe den Fall an die Staatsanwaltschaft Münster abgegeben, teilte der Kreis Coesfeld mit. Der Vorfall habe sich bereits im April ereignet. Das Tier war aus Frankreich eingewandert und stammte aus einem französischen Auswilderungsprogramm.

Den Senderdaten zufolge dürfte der Jungadler am 1. April 2023 abgeschossen worden sein. »Es ist kaum vorstellbar, dass dieser große und auch auf größere Entfernungen sehr leicht zu identifizierende Vogel versehentlich geschossen wurde«, sagte Detlev Terlisten, Leiter der Unteren Jagdbehörde im Kreis Coesfeld.
GT:
A strictly protected white-tailed eagle was shot and beheaded in the Münsterland nature reserve Letter Bruch near Coesfeld. The animal's claws and head were removed after death.

The Coesfeld district announced that the case had been handed over to the Münster public prosecutor's office. The incident happened back in April. The animal had immigrated from France and came from a French reintroduction program.

According to the broadcaster's data, the young eagle was shot down on April 1, 2023. "It's hard to imagine that this large bird, which is very easy to identify even at great distances, was accidentally shot," said Detlev Terlisten, head of the lower hunting authority in the Coesfeld district.

These are amazing news about the WTEs reintroduced in Haute-Savoie, France. Of one of them, we have sad news, see post above. But one of the remaining three, equipped with a transmitter, shows their travelling quality 8-)

https://www.altitude.news/fun/2023/07/0 ... ent-monde/

GT, quote: "One of the four released eagles even broke all records while traveling through Europe. They each bear the name of one of the operation's partners, this one being called… “Crédit Agricole”! He first took up residence in Switzerland. He spent the winter there before traveling through Germany, then Poland and even Denmark. Crossing the Baltic Sea was no more than a formality. After hundreds of kilometers to go up Sweden, he arrived in Norway at the end of a journey of nearly 3,000 km. Two others are also walking from the Czech Republic to Austria. The fourth died, shot by a poacher in Germany . The three eagles should continue their journey but return to their region of origin, around Lake Geneva, as adults. Next release next September."

(Of course, two of them are certainly not "walking" (oh Google ...) , ils se promènent, says the text in French, which is a nice way of describing their roaming between the countries.)

Dec 2023:
https://www.birdguides.com/articles/orn ... ed-eagles/

Quote: "A new study has shown that lamb is decreased as a food source of breeding White-tailed Eagles in Scotland, with seabirds and fish the main prey.
The research assessed the diet of eagles between 1998 and 2017, establishing that the occurrence of lamb in their diet has decreased as more pairs have become established.
The analysis of food remains showed an incredibly diverse diet during the breeding season. Some 11,375 different food items were recorded in 293 samples from nest sites in 92 White-tailed Eagle territories across Scotland. No fewer than 121 species were recorded, with 70 species of bird, 17 species of mammals and at least 30 species of fish. "
(...)
"Robin Reid, one of the paper's authors, said: "This publication has been made possible through collaboration between many researchers and fieldworkers and with support from several organisations. As a result, the findings are based on large and robust dataset with prey remains collected from the majority of White-tailed Eagle territories occupied in Scotland during the study period."
"It has been fascinating to see how the diet varies between individual territories and across regions. The wide range of prey items recorded demonstrates that the White-tailed Eagle is an opportunistic and adaptable predator and scavenger, consistent with findings from studies elsewhere across the species range in Europe."

Modern English poetry discovers the White-Tailed Eagle, s. here:

https://www.zocalopublicsquare.org/2024 ... es/poetry/

White-Tailed Eagles, by Jane Clarke, also read by the author, s. link above - quote:

"Iolair Mhara

Two eagles lock talons in mid-flight
and tumble together towards the water

    as if they’ll never stop falling,

but they disentangle just in time
and ascend to the top

    of a scraggy Scots pine.

Still as Ross Island
they roost side by side,

    till one of them lifts,

glides over Lough Leane
then makes a thunder-bolt dive

    before levelling to snatch a salmon.

Will they settle,
build an unruly nest,

    fledge chicks that will spread

from here to Loch Iolar, Binn an Iolair,
Iolard Mór and Iolard Beag?"
