Your residence may determine which species of bird to purchase. The purchase of a bird is a life long commitment and you will want to avoid any potential problems with your neighbors which could result in having to find a new home for your pet. Aratinga Conures, Cockatoos, and Macaws can be quite loud with their daily chattering and screaming rituals. When you are visiting pet stores and breeders be sure to listen to the birds vocalizing. Birds vocalize to communicate and you should expect and be able to tolerate a fair amount of chattering and screaming from a pet bird.
Birds can be quite messy.
Birds have delicate respiratory systems. They need to be housed in pollution free environments. Cigarette and cigar smoke can cause lung cancer in birds. Air fresheners, pesticides, non-stick coating pots and appliances, cleaning solutions, and other fumes can kill a bird instantly or from long term exposure. If you can't live without your air fresheners, cigarettes, and non-stick cookware then do NOT purchase a bird.
