A foreign stork, banded at the left leg, landed on the nest.

It was interesting to see, how the youngsters were behaving.
Luckily the foreigner was not aggressive against the youngsters.
Edit:
And here is Part 2 of the Video until the foreigner left the nest.

Some minutes later Cico fed them and they made some wild jumps.
Luna also came and fed the youngsters.
So I think, they have forgotten the visitor and are back to usual stork busines.
