Liz Wilson, an avian behavior consultant from the Philadelphia area, has some strong opinions about how birds should be treated. She advises, "Don't dump the bird. Fix the problem."

Many parrots start biting as juveniles, when they start asserting themselves to see who in your family will be the flock leader. Of course, the parrot hopes it is itself.

Birds mimic human voices because they enjoy communicating with their social group. Some species are better mimics than others. Even birds that are not tame have the ability to mimic and talk.
