My favorite birds are owls. They are so beautiful and so cool! My husband keeps watching YouTube videos of tame baby owls and keeps saying he wants one. I keep saying "no dear"!
My favorite companion birds are budgies. They are so underrated. The first budgie we hand raised, our girl Rocky, is incredible. She hates hands and doesn't talk, but is very bonded to us, yet independent at the same time and we just adore her! I have some big beautiful English budgies now, too (Rocky is half English). They are much calmer than regular budgies and are so big and fluffy I just want to squeeze them (in a good way) but I don't.
I would love a green cheek. They're just the right size and seem like great companion birds but I've got my hands way too full with all my budgies!
Cockatiels are also awesome birds. I had one years ago, Charlie, and he was the sweetest bird that never gave me any trouble.
