That's funny Popcornbird!
I always wondered what it means when a Cockatiel has their crest up or down, what mood they are in.
Parakeets just have a round head and don't seem to be as expressive as Cockatiels who can move their head feathers up and down.

I think T-bird's favorite wild bird song is the Robin probably because it is one that she hears outside all the time and likes to talk to.
