3 parakeets that we've never bothered to name; we usually just refer to them by their respective colors, e.g, white bird, yellow bird, blue bird. We found a cockateil that had apparently been trained by a previous owner wandering around our neighborhood one day, whom we kept for a few months or so. I'd have liked to keep him, but the parakeets were enough work as it is, so we gave him to a senile friend of my mother. Over time, he grew quite bitter and refused to be touched by anyone, and he developed a peculiar taste for meat, including chicken. He later died after coming into contact with a teflon pan.
Oh, and I had a pair of hermit crabs years ago. They weren't very interesting.
