I just saw Rio hanging from the top of her cage ... and she was completely upside-down. She looked like a bat! This is the first time I've seen her do that. I've seen her climbing around her cage before and sometimes she crawls (using both feet and beak) across the top of her cage, but I've never seen her hang completely upside-down. I went up to her and talked to her and she just looked at me and continued to stay upside-down. I'm not sure what she was doing before I saw her in the position. Anyway, I'm just wondering if a lot of birds do this. When I had my cockatiels, I've never seen them this. However, Bijou is always hanging upside down when she's out of her cage (this is how she watches what's going on in the room).
