Thanks to all for your comments on my budgie dilemma. I think I frequently fall into the trap of anthropomorphizing my animals and in trying to do what I think is best for them, I end up doing something they may not like. After all, since parrots are flock animals, surely they'd prefer to have another of their own kind living with them, right? Ha! Just look how well that turned out for my caiques and greys. Why don't I learn?
Luckily, that other budgie found a great home. Later that day, I got a message about a tame budgie with neurological problems -- might I like to take him home? I got that message after the deadline passed (another volunteer took him home) so didn't have to make any decisions there. I think it's best Brian remain an only budgie. Perhaps someday I can have a budgie hospice, with enough budgies so they can choose their own partners, and enough space so they can get away when they'd like.
As was pointed out to me, he's only ever lived with humans, and may not welcome a budgie companion. Also, since some birds will try to drive out sick members of the flock, I wouldn't want anyone to harm him (due to his tumor) or for him to harm the newcomer.
All this talking and thinking about budgies made me appreciate Little Brian even more this weekend. Thomas was drinking from a different water bottle than usual, and Brian was entranced:
Thomas was trying to read a magazine, but Brian wanted some attention:
