I'm glad you clarified that you meant wild birds as pets as they 'stay' wild. As a wildlife rehaber, and I have seen way too many people actually make wild birds as pets from being found as a baby, injured etc. We need more people to leave the wild in the wild and utilize wildlife as our 'free born' pets to come and go as they please in their natural environments in the city or country. By providing good quality feed and shelters, wild animals can make very good 'pet's so to say and we all can learn a great deal from them all!
