One additional similarity I'm sure you are aware of: birds, like humans, seem to have a 'critical period,' a time frame in which song/speech must be learned. If birds don't learn a song by the end of this period, they never learn to sing properly; sparse evidence suggests this is the same with humans.


Note that some male hummingbirds chirp with their tails during high speed manuevers to impress females. See Ed Yong's post at Not Exactly Rocket Science
