This morning we see first one and then both - the second a little bit
10:53

11:09
I suppose we must watch a longer time to see the movements or if there is nothing at all
edit: I think I was wrong with the second picture of 11:09. This was not a raven - I looked at all my pics around and found out that this movement was under the bottom of the nest - it was on the ground of Talinn.
So the first little raven have left between the evening of 17th of May and the morning of 18th of May.
