Mazais Erglis~ Fly high little #2 💔😪 that was a short live~6:12 am 2023/06/12

Andris brings a prey . Anna pulls little #2 Mom out of nest bowl. She eats part of #2, offers a few fluffy feathers to #1 , then she flew to her resting tree with it. I'm sure, she has eaten it there. #2 has eaten just a few bites in it's short live.

📍 Cainism in lesser spotted eagles:
Author: Bernd-Ulrich Meyburg
The following factors are responsible for Cainism (fatal Cain-and-Abel struggle) in the Lesser Spotted Eagle: 1. The time lapse of several days between the hatching of the two chicks, giving the first-born (Cain or C1) a more or less considerable developmental advantage. 2. Cain's greater weight at the time of hatching. It usually also hatches from the larger egg. 3. The aggressiveness of the chicks towards each other. 4. The acceptance of intimidation by the inferior chick, even when there is virtually no difference in weight (e. g. in translocation experiments), to the extent that this chick hardly ventures to take part in feedings. 5. The scant attention paid by the female to the second chick. given its smaller size and, above all, its greater clumsiness in taking food due to its retarded development, shows that it holds a waning power of attraction. The food supply plays no part in this. At this time lhe nest contains an ample supply of prey. Up to now there has been much disagreement over the meaning of second-egg laying, leading as a rule to the fledging of only one young, and over the significance of Cainism within the framework of evolution in this and other eagle species. None of the attempts to explain it so far published is really convincing. One possible explanation for the phenomenon of Cainism may well be that the species is at an evolutionarily intermediate stage of transition from two-egg to one-egg clutches. For unknown reasons, and in contrast to earlier times, the raising of one young per breeding season is today sufficient to maintain the species. At a later stage in the course of its evolution this species, which at present lays a second egg clearly smaller than the first – one could regard this as vestigial – may well confine itself to laying no more than one egg per clutch.

The nest is situated in the western end of Zemgale. It was found in 2018.
The nest is built in a spruce at a height of 17 metres, on a stable three-pronged branch. In terms of location, it can be assessed as a typical Lesser Spotted Eagle's nest – about half of all Lesser Spotted Eagle's nests in Latvia are located in spruces, and a large part of them is built in the places, where the branches have formed several new tops at the trunk fracture. Judging by the size of the nest and the condition of the material, the nest is at least five years old.

In 2019, the nest delighted the audience with a harmonious nesting – a couple of eagles, Anna and Andris, raised one nestling, who grew calmly, in conditions of abundance of food and fledged successfully.

The camera system at this nest was installed by Jānis Ķuze and Jānis Rudzītis. Thanks for support to Jānis Kažotnieks and Renāte Kviese!

The operation of the live camera at the Lesser Spotted Eagle’s nest is provided by the Latvian Fund for Nature within the project "Ensuring the Protection of the Lesser Spotted Eagle in Latvia" (LIFE AQPOM), financially supported by the European Commission's LIFE+ program and co-financed by the Latvian Environmental Protection Fund.
