Well if parrots can live in NYC winter, I guess they're tough enough ;^) I just get peeved over people that complain I'm keeping a wild animal in a cage. I know he's happy, and I make sure he is. He's talking to me right now. They must not understand what is required to care for an animal.
That's just it. You are keeping a wild animal in a cage. Can he be happy? Sure, because you love him and take care of his needs. But, not everyone treats their birds so well or are able to properly deal with them. That's why PETA wants Petco to stop selling these wild animals as pets.
Domestication requires thousands of years of breeding. Parrots are only a generation or two at most from their wild brethren.
But, Petco doesn't tell anyone they're buying a wild animal when they sell a large parrot. Instead they tell the prospective buyer they're buying an animal that'll be a perfect pet for kids, grandma, or whomever else they can think of to get you to buy the bird. And they don't care what happens to you or the bird once the sale is made.
That's why there's literally thousands of unwanted birds in hundreds of rescues across the country.
