Asteria, yes, of course you are right - the story is in the Oson video.
Although it is about the Belgian black storks. Ain Nurmla tells that one of the storks even threw the marten down from the nest, but it came back, and ate the remaining eggs.
Sorry, I didn't listen or look very carefully before I put the link up.
An awful climb for Ain Nurmla - and no gloves on either
Felis - I haven't been looking very carefully at the LK stork nest environments. But the Osoon one is said to be in a birch, several times, and that we have not had on LK cameras. Also, it is said to be near the Latvian border.
The harassing bird - or the most serious of them - was said to be a WTE.
Ain Nurmla also says they are putting up 12 track cameras this year (re-named self-photographing cams
, "isepildistavad kaamerad")
Subtitles: sparingly done in Estonian productions overall, it seems.
