While scouting at the pond near Mikepércs I met a few coots which seeing me started to get away rapidly. This nestling plunged under the water and when it came up this green algae stuck to its head so that it couldn't see anything. It stayed unmoved a little then when it noticed that no one helped it shook its head, got rid of the algae and rushed after its family:

And this is the first black tern I met:
