My Cockatiel which is around 3-4 months old, seems to make noises that resemble "Talking". These noises are often made when it is in a free mood but not in any other uncomfortable situations. I'm worried if it is trying to convey some kind of message that I couldn't understand.
I have two cockatiels. One is very active- (easy going, playful) and the other one is very calm going, (but often attacks with beak when I try to take it into hands) and only active when it needs to have fun. The cockatiel which is not always active/playful has this "Talking" behavior. I have noticed this behavior since not more than a month. The other cockatiel doesn't bother/respond to these sounds.
