Bird brain. I don't take that as an insult. Bird brain is actually just my speed. I don't have the energy or extraversion necessary to being a dog owner (walks, other dog owners) and I don't like not being adored by cats, so birds it is. (We already have fish, but they remind me too much of myself, going around and around inside a bowl.)
Friends have a pair of zebra finches they raised from eggs, and I was smitten by their wildness (they are not "pets" to be "petted") and their sociability. Wildness, sociability and flitter, being exactly what's missing in the work-from-home habitat that I've dug for myself in the spare bedroom I call my office. It's dark and lugubrious.
I need some light-hearted pals who will pull me out of myself with their aerobic antics, and chitchat. So what if we're not the same species? I saw a PBS show about a dog who became friends with a cheetah, and a deer who became friends with a dog.
