15:25:25 a bird landed on the right . that looks like a white tailed eagle
15:31:09 WTE? is flying from the left under the nest tree
15:31:13 landed on a tree on the right
15:32:20 flew from the right to the left
15:33:40 flew from the left to the right. and yes, it's a WTE. We saw one WTE in the past. He could not land into the nest. His wingspan is to wide. But he/she was on the nest
15:10 she rolls the egg and covers it.
Now Goshawk, no WTE till now
15:56 it looks like she is in labor
15:58 she is in labor
16:04 she laid her second egg. Oh dear.. Hooray Exciting times are ahead.
she rolled it the first time
16:05 she covers the egg
Sometimes she lays one egg, sometimes 2.. unusual, I think

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. https://www.researchgate.net/publicatio ... a_pomarina
13:10:55 an eagle (LSE likely) flies left to right behind nest, low down. Anna reacts calling standing.
Anna leaves 13:11.30 calling all the while.
Andris in for a shift at 13:12:27 being a wee bit clumsy with his talons as he settled on the eggs. Lots of calling in the distance - Anna? Surely she should be eating, one hopes.
13:20 normal service resumes with Anna in and Andris out.
Nothing further of note it seems. As someone observed - cold weather and the mice don't play.
Exciting times are ahead.
