And I wouldn't let them. As Chester has a deep hatred for all birds, and the cockatiels can be incredibly annoying, they are never out at the same time. This means there are almost always discontented parrots here. To combat this irritating fact, both Yo-yo and Chester have started to take advantage of the simpler door latches on their temporary cages.
Yo-yo has actually succeeded in his quest, something he is quite proud of. It is not the easiest door to open, as it has to be lifted up and pushed out and down. Still, he has figured it out. This means he can not only get out when it is dangerous out of the cage (i.e. Chester is loose) but also is in danger from the door itself. The second time he tried to open it (the first time I convinced myself I had left it open, which I am sure was very amusing for all others involved) he had a very narrow escape with being choked. He managed to open it partway, and re-lock it on his neck. Fortunately, I was in the room, and was alerted to his predicament by the strange strangling noises coming from the cage. Don't worry, he was fine after being released and cuddled, and has suffered no long term damage. However, it puts a lot of pressure on me to remember to lock the doors every time; I have forgotten, though he fortunately managed to open the door safely.
Chester has yet to get the doors open on his cage, but not for lack of trying (and frustration at Yo-yo's new found ability!) He has to lift a latch to get the door to open, and is getting very close. I am beginning to wonder whether I should lock the doors now before he figures it out, but then, he is so dedicated to it, I figure a nice puzzle is good stimulation!
Of course, Frank can already get out of everything, so his doors had large locks on them from the beginning!
Ava is the only one that seems disinterested with doors. If she wants to get out (she is only locked up if Mr. Green Jeans is out) she climbs to the top corner of the cage, and curls up into a little ball, with her beak on the bar, and her feet on either side of her head. Awkward, I know! Once in this position, she alternates between pushing hard against the bars with her body, looking at me and begging (sort of, that position, you know......) and calling to be let out. Very convincing, and I must say, very effective!
