Great idea, bad implementation I would love this application, but it simply does not work. The english descriptions won't show... maybe they don't even exist. The czech texts are sometimes there, somethimes missing. The sound player controles should be either disabeled when no recording is selected, or a recording should be always selected... this way it's confusing.
no english not many birds
English does not work, very limited amount of birds
