When I bought my 1st house up in Minnesota, I rented a spare bedroom out to a former next door neighbor from when I'd rented a room in a boarding house while I saved up to buy the house. He was a pheasant hunter and would live trap pigeons to train his bird dog and one day came home with an African Grey parrot he'd live trapped at a granary. The workers told him that the bird had survived the winter that year by perching in the rafters where he was kept warm by the raising warm air coming off the grain fermentation. He figured it had to have escaped as someone's pet but as it had reverted to wild he had to very slowly gain it's trust and re-domesticate it. But the thing was mean to me if I tried to get near it and it would fly around the house chewing on the tops of the bedroom doors, ruining them and anything else it fancied. I wouldn't mind getting another Amazon species but I'd probably pass on a Grey.
