Not only from their bold colors, but from their funny personality. They are relatively quiet as far as no squawking, but can still make high pitch calls, learn various whistles, and mimic other noises as well. The White Bellied Caique originates in South America. They weigh about 150-170 grams are about 9- 10 inches in length. Their diet in the wild consists of fruits and seeds. Caiques also have an oil preening gland to clean their feathers, so those with allergies may consider one of these guys.
