Beeps has recently begun flying to Calypso's and Max's cages to play with their toys and eat their food. He's smart enough to only go to Max's cage when she's in the kitchen as she would not like him to be on her property!
I was in the kitchen when I heard Beeps take flight. I had to investigate to make sure he wasn't getting into trouble anywhere (like chewing the lizards' electrical cords).
Both caiques were on Calypso's cage -- that's Calypso up top and Beeps on the door. Despite living together for almost three years, the caiques still pretty much ignore each other, so this was rather interesting. Calypso was fine with Beeps being on his cage as long as he didn't get too close!
