28th of March, about 12 pm, the recording was made by the lake where mallards and goldeneyes swim, I didn't see any birds while recording - only frogs, I upload two files: The first one is the whole recording and the second one is the call cut from the first recording, sorry for the poor quality but the bird was in a distance. The unknown call
is the duck-like sound.
