In the photo, it looks much closer.ame wrote: ↑September 12th, 2019, 10:27 am 7:38 - 7:45 a hooded crow (Corvus corone cornix) was on the top of the spruce on the right.
the crow called at about 1 s intervals and nodded its head each time. the nod was about 0.5 s offset from the call. speed of sound is 330 meters per second. so the tree is about 150 meters away from the nest tree.

Maybe the sound doesn't match the video again?

It sounded as the fish song.
These spruce can't be both behind our backs as all three stand in a straight line. The camera gives a view of more than 180° and one of them we must see. If we don't see the spruce on the left, we see the spruce on the right.
