Actually that picture was taken yesterday, and he was excited to get a shower.
He is very big on flashing his eyes and tail when he is excited (in a happy way) about things like showers and treats and toys and singing. He has been literally 100% trustworthy and darn near cuddly up to this point. He loves his head scratched, and his beaky wrestled, and will melt into a feathery puddle if you give him scritches on both cheeks at the same time.
Today is totally different. While he's definitely "feeling" something, its not his happy go lucky excitability I've seen previous to today.
I approached his cage a few minutes ago, to give him and my grey some seed (treat time!) and he was smashing his face up against the cage bars trying to get at me while I stood there. Something he has NEVER done before.
If I didn't know any better I'd say someone snuck in while we slept last night and swapped out my sweet bird and left this demon in feathers.
