maybe she was just letting her breath cool down. it sounded painful again.

i'm watching your video from earlier today. great that you have a recording which starts well before that strange incidence began.
i saw part of it while in another window (while i was downloading it). at the same time i was watching the second egg arriving...
it seems to me that there may have been an intruder after all. Linda is staring at something and Sulev begins to call near the nest outside the picture... and then Linda calls and a nuthatch... maybe the sound is mismatched again?.. Linda seems to be calling at 12:44. she looks annoyed.
12:44:40 picture time both voices. then Linda screams in picture... a lot and for a long time.
i see no reason why she would yell at Sulev like that.
17:46 picture time both voices. 12:47 Sulev comes to left branch and just seconds earlier Linda rises and spreads her wings and begins to yell. then both yell together.
i think there had to be an intruder which we never saw. both were upset about it and defending the nest together.
