This morning my sulphur crested cockatoo was squawking quite a bit which isn't normal for her, she's almost dead silent most of the time except for when she says "Good night" repeatedly. I let her out and now she is sort of spinning back and fourth on top of her cage with her wings stretched out, sometimes fluttering. If I come up to her she is not aggressive, she stops for a moment and says hello but doesn't want to step up. I don't know if she is in pain, if she is just goofing off or maybe she is getting very hormonal this spring or something? She spins 180 degrees, grips the cage with her beak, then spins back 180 degrees and grips the cage again and she keeps doing this over and over again quite quickly. It has been 5-10mins of her doing this now.
