You can rescue some as I have. Birds are very unique and fun, but fragile and want as much love as they give (which is a lot).
I have two conures, one was "too loud" and ignored in the corner of their garage for a few years until he started pulling out all his feathers and chewing off one of his toes, at which point he was donated.
It took about a month to get him to trust me. He will not stop attacking his own feathers, but now does so in a relaxed, quiet way while on my shoulders. He loves to just hang out with me while I'm doing some design work or programming, calling from the open door of his cage in a certain way when he wants to shoulder surf. He's afraid of everyone else, but I know him, his body language tells me that he likes being around me.
They are a unique gift in terms of a life form. I wouldn't buy one. Go for a rescue, try to sense their personalities as you talk to them.
Suddenly, there was a terrible roar all around us, and the sky was full of what looked like huge bats parrots, all swooping and screeching and diving around the car, and a voice was screaming: "Holy Jesus. What are these goddamn animals?"
'E's not pinin'! 'E's passed on! This parrot is no more! He has ceased to be! 'E's expired and gone to meet 'is maker! 'E's a stiff! Bereft of life, 'e rests in peace! If you hadn't nailed 'im to the perch 'e'd be pushing up the daisies! 'Is metabolic processes are now 'istory! 'E's off the twig! 'E's kicked the bucket, 'e's shuffled off 'is mortal coil, run down the curtain and joined the bleedin' choir invisible!! THIS IS AN EX-PARROT!!
I took it to mean they used to have a parrot that was in the store and would roam freely (used to be fairly common in pet stores in areas I have lived). So they still may have parrots, just not a free roaming one that claws at peoples eyes and nips at fingers and ears. Peter was one crazy parrot... they got tired of having to hide all the bodies.
