So you think you know your Southern African bird calls? Then prove it by taking this tough test. Be warned: although these clips are all from fairly common local birds, they are unusual calls that are seldom heard and poorly known. I'll also give you some clues if you get stuck. If you get none right, don't worry...I won't publish the results :) But this just goes to show how wide the repertoires of birds are. They have a whole language, that we are only beginning to document. Good luck!
