I wonder what a bird would sing if it didn't have its parents around (or any other birds for that matter) to learn its chirping sounds from.
I'm interested in how a bird would sing...
- in complete isolation from creatures communicating through sound;
- in isolation from its own species, but with other birds;
- in isolation from all birds (other animals and creatures are there for it)
- Would a bird even feel the need to speak up if there wasn't any other vocalizing creature around?
- Would a bird learn other species' signals? Would it only learn from one species, the one which it would think of a fitting mate?
- Would a bird try to mimic a non-flying creature's signals?
These are similar questions, but if you think they should be separated, let me know in the comments.
