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.
