Sonchik, i think that they are just keeping guard in case someone should come. i don't believe that they see anything and i think they are happy about it. they have to watch and see if the forest is safe or not. safety is utmost important for them now.
I had such thoughts too. Thanks for explanations!
Milda is not subordinate nor obedient. she is The Boss.
Did not you see?
I so laughed! It at first opened a beak as though wants to tell something. Then he opened it in spurts, as if it was rusted.
Milda was shocked!
I can write only from phone when I have a record. It very long. Until I write, already all will write about it three times. I thought that all see it too and I do not write. It appears see not everything. But I cannot guess in advance.
btw: big birds like swans and geese migrate as far South as they have to, not farther. swans need open water for feeding and geese open feeding grounds. the archipelago between Finland and Sweden is full of swans, both whoopers and mutes. some swans even don't migrate at all. there is a group of swans staying in Kajaani in northern Finland (actually in the middle of Finland) in a river which stays open all winter. https://yle.fi/uutiset/3-10014890
7:50:20 (about) the voice again.
7:51 Milda got up to the top branch and called.
maybe there's a stranger in the forest.
7:52:03 again the kaa-kaa-kaaaa.
the voices sounded very much like the voices which we have thought were by jays.
this time i think, however, that the origin of the voice was another eagle because Milda seemed to react to the voice. https://youtu.be/PoPI1ZNE1UU
