Why is my bird sleeping lifeless on the top of the brim of the shut within he other sleep on his stick? why?
Answers: Some birds just do that, I had two Sun Connures that would sleep hanging upside down resembling bats. They loved it. the only time to worry is whether they sleep on the floor, some times they do that when they are sick.
Maybe he feels like doing something different so he decided to sleep upside.
