Hello all, Here is my little tame guy! I just had a few questions on Bourke behavior. Do they show that they are happy much like a budgie would? Its hard to find info on their body language. My little fella will puff up the feathers around his beak in what I call his "walrus look" and gride his beak. Is this signs of a happy bird?? Also just suddenly he will start to do a few head bobs. He doesn't do this in his cage that I have seen, but when he is out socializing with us. Its just a few head bobs and we figure its just him being silly?? Any incite would be great!
