... i przygotowywałam "wystraszenie kuny przez bociana czarnego" (... and I was preparing "black stork scaring the marten away")
13:33:17 one black stork flew over/very near the nest
I didn't manage to capture it in the picture, I could see the wing (waving the wing) for a very brief moment
the marten first followed the flight (?) of the stork, then the great tit, which was on a nearby branch, and only then disappeared behind the tree trunk
