I got the feeling that he was happy not to be outside anymore and he initially just wanted to sit on top of the cage and talk. I think now that he may have been trying to find his traveling pal. Once we got him some places to perch he seemed content just to chill. He drank water but we couldn't get him to eat much, I think he basically just relaxed to the point he passed. Poor dude just had no energy reserves and was literally dead tired. Makes me sad but at least he wasn't cold, scared and alone at the end.
