Parrots are extremely intelligent birds. Over time they can learn, not just to imitate human speech, but to build associations and use words to communicate their needs. They create the sounds of speech by manipulating the air through their bills with their tongues, and they'll play with sounds and words like kids with toys. They're very social animals and love human company. They also love to chew things (including the corners of my kitchen cabinet doors, once.) They also bite. Hard!!! So if you are lucky enough to encounter a parrot, beware the beak tweak.
