thank you Sonchik!
yesterday i had a break in the recording at 18:27 - 18:50.
19:56 i could not find anything.
6:01 was an eaglet, i don't know which.
6:28 was perhaps not an eaglet but a jay?
6:52 were voices from old McDonald's farm: a dog and a cock. a blue tit called near ans an eaglet, too.
so i did hear an eaglet when the little birds visited the nest. i was not sure.
i made a clip starting at 8:15. i added the beginning of the fish song here:

then the little birds examined the nest for about 10 min.
