In my free time, I like to study bird vocalization, which includes bird calls and bird songs.
That's interesting, is there a special name for that? Can you tell me some more about it?
Well, there's not really a special name for it. But I can tell you that songs are generally used for courtship, while calls function more as an alarm or a way to keep members of a flock in contact.
That makes sense, do you know a lot about birds in general?
Well somewhat, but my expertise is mostly about this kind of thing. I do know that some groups of birds are nearly voiceless, they produce only percussive and rhythmic sounds.
That's interesting, do you know what groups of birds specifically?
Well one example of these kinds of birds are storks, which clatter their bills to communicate.
