Many birds in the parrot family experience neglect and abuse.
Maltreatment can cause these birds to pluck out their feathers and mutilate themselves.
Janet Trumbule, executive director of administration at The Oasis Sanctuary, said this behavior is usually stress related.
"It could be lonliness, it could be boredom because they aren't given any toys, but once a parrot starts that plucking behavior, it's very hard to get them to stop," Trumbule said.
The sanctuary is located in Cochise County, southeast of Tucson, and is home to more than 700 birds of various species.
Some of the birds end up at the sanctuary after being confiscated from those trying to smuggle them across the border. However, most of the parrots are there because their owners changed their mind about having them as a pet.
"These (parrots) are such a lifelong commitment," said Kathryn Yochis, caretaker at the sanctuary. Many of them live 60, 80, even 100 years. If you don't understand what that means, don't go near it."
There are only a few accredited sanctuaries across the country and all of them are full. Oasis currently has a waiting list of 150 birds.
