Salty has always been covered at night, with a black cloth. His summer one is not so heavy that some light leaks past it. Since we switched back over to his autum, winter one, he seems almost terrified when I pull it over the cage. The winter one is heavy black out curtain material. Is it possible he's really afraid of the dark? He conks out pretty quickly, with maybe a chirp or 2, always has. But he almost coweres against the cage bars, and bites at the cover. I;d would be horrified if he was really afraid of the dark, and no way to tell us about it. I'm thinking of putting a small night light under there with him, out side of course, with wires well away. Does anybodies bird suffer from something like this? Please.. input? I would do anything, spend anything , to make sure he is comprtable .
