HottJoe saidJust move to an area with lot of trees and you'll hear them singing every day.
There is a huge difference between domesticated pets and wild animals kept in cages. In the case of birds, they usually get their wings clipped. A lot of birds panic from being trapped in cages and self mutilate. Birds just don't develop healthy relationships with human pet owners, like dogs and cats do. They're just being robbed of their nature, which is to fly, migrate, and often mate for life.
I don't know where you get your information from, but that's completely wrong. Most pet birds can form bonds with their human owners if they are treated well from the beginning. They can play outside of their cages if they are trained from an early age. Wing clipping is only to protect them from flying out of the house, and many times, it calms them down because they can't work themselves into a frenzy. It's not worth fighting about though.
I got my latest information from a PBS documentary about Parrots. Probably one of the most heartbreaking things I've ever seen.
There is a vast, vast difference between the behaviors of wild-caught parrots (an absolutely inhumane process that has been banned in the US parrot trade since the 1990s, thankfully) and those of captive-reared parrots. I've had my conure for 13 years, since she was nine months old and hopped on my shoulder as I walked by in a pet store and refuse to leave (really). She is fully flighted and is only restricted to her cage at night -- when she goes to her cage and puts herself to bed -- or when nobody's home. Otherwise, she prefers to follow her people around. She tries to bathe in my water glass, she terrorizes my cats, she runs around throwing veggies everywhere when I'm cooking, and she mutters 'stop it, goddamn it' if we make too much noise when she's trying to sleep. She dances excitedly when I come home from work and asks for kisses and pouts when I leave.
In other words, she's quite bonded, and more happily domesticated than my boyfriend.
Generally, parrots self-mutilate out of boredom or agitation. Treat them well and keep them entertained, and there's no problem.
As for cats...they're more self-sufficient than many gay men, so I like 'em.
