Bird sanctuaries are nature facilities that advocate the conservation of various species of birds and their natural habitats while promoting rehabilitation and survival. Most sanctuaries exclusively help birds, but some include other animal species. The birds helped are unwanted pets, endangered species or local wildlife.
Many birds go to sanctuaries as a result of their owners' inability or unwillingness to continue caring for them. Private pet owners transfer the largest number of exotic birds to sanctuary facilities. Bird sanctuaries are also established to protect the birds of the area from suffering due to territory lost as a result of commercial development.
