     “Our big finding is that masturbation is not a negative response to captivity,” said Dr Chloe Heys, an evolutionary ecologist at the University of Lancashire in Preston. “This is widespread in birds and we found it’s a perfectly natural and healthy behaviour that’s part of their repertoire of sexual behaviours.”¶Researchers historically tended to assume birds either did not masturbate or did so only under the stress of captivity. But Heys said the behaviour was quite common and distinctive. “I had a pet cockatiel that masturbated all the time,” she said. “If you’ve ever seen a bird masturbate, you absolutely know what that bird is doing.”
