Toiko se emo tälle pokaselle ruokaa? Emo rengastettu.

Katsoin hidatusta. Tyhjin jaloin tuli ja jotain yritti ottaa pesästä, mut poikanen tarrasi jalkaan.

Kiitos marksaa tiedotteen jakamisesta! Hirveän näköinen tuo pelletti tai mikä ikinä mömmö onkaan EE1:n nokassa. Toivotaan, että Eva ja Eerik ovat kunnossa.

Kummallista, että poikaset saavat lintuinfulenssan, kun ovat pesässä, mutta emot jotka lentävät pitkin ja poikin maailmalla eivät sitä saa? Sama Tanskassa, toinen poikanen menehtyi siihen, mutta toinen säästyi!

Tässä tuo Kotkaklubin tiedote käännetty englanninkielelle

. provided by Triin
Autopsy confirmed that the cause of death for chicks was avian influenza H5N1 ("bird flu").

GT:
Press release of the Estonian University of Life Sciences (19.05.2021)

... An autopsy performed at the Estonian University of Life Sciences revealed that the eagle chicks died as a result of the H5N1 bird flu.

According to veterinarian Madis Leivits, who determined the cause of death, the eagle chicks were infected with an aggressive strain of bird flu that has not been encountered in Estonia before. H5N1 is a highly contagious and dangerous strain of bird flu that is known to infect mammals, including humans.

Man's desire to experience nature as closely as possible is natural. For a long time now, one such option has been real-time nest cameras, which can be used to experience the joys and sorrows of families with birds without interruption. According to scientists, nature cameras actually have a much broader function, helping us to understand the life and needs of animals in nature, through which we can better co-exist in a common living environment.

The white tailed eagles nest camera located in Matsalu National Park and installed by MTÜ Kotkaklubi is extremely popular both in Estonia and abroad. All the joyous events took place on April 28 and 30, when the eagle chicks hatched. The newborns were cared for by adult birds, offering them a variety of food (fish, game carcasses and waterfowl).

Last week, however, the nest was hit by an accident: the chicks suddenly became powerless and died on consecutive days at the age of about two weeks. The case raised many questions among nest camera watchers and bird researchers, so it was decided to investigate the cause of the chicks' deaths further. MTÜ Kotkaklubi, Estonian University of Life Sciences and the Environmental Board coordinated the collection of dead chicks and remains from the nest and the transport to Tartu by the Institute of Veterinary Medicine and Animal Husbandry of the EEC.

According to veterinarian Leivits, at the initial examination, the older son (EE1) had a rather large lump between his beak and throat (parts ingested with undigested food are usually vomited out). The pellet, which consisted mainly of hay, was also in the throat of the smaller eagle chick (EE2). Whether this is normal, we do not yet know, Leivits said.

The necropsy found that most of the tissues in the bodies of the dead were altered. The organs were fluffy and abnormally colored. Bruises from various tissues could also be found, and the lungs were filled with mucous-foaming foam.

Primary samples tested positive for family A influenza virus. To confirm and type the finding, a sample of the lungs was sent to the Veterinary and Food Laboratory, where the H5N1 avian influenza virus was confirmed.

The disease probably reached the nest with waterfowl, which were used as food by the eagles. Waterfowl are also a natural reservoir for influenza, Leivits noted, confirming that this is a natural process in nature and that diseases are also part of nature. "This strain of influenza has not been encountered in Estonia before, which does not mean that it has not occurred in our nature before," said Leivits.

He hoped that the adult birds, which ate the same food as the eagle chicks, would be able to recover from the disease and be able to weave their nests again next year and raise their young.

Avian influenza H5N1 is also important from a human health perspective. Namely, the virus has the ability to spread and adapt quickly, overcoming barriers between species, including humans and other mammals. "This finding reminds us of caution and the fact that incompetent intervention can endanger our own health."

The spread of diseases plays an important role in humans through their activities in the environment, directly by transporting viruses or by changing the living environment, as a result of which pathogens spread more successfully or the resistance of animals is inhibited.

Enpä osaa sanoa, onko pesän asukas, mutta ihanaa, että joku kotka on hengissä. Pelkäsin, että lintuinfluenssa on kaatanut kaikki, kun hiljaisuus on ollut totaalinen pesällä.
