A forest canopy dweller, both species of Caiques (pronounced like "dike" with a k) are found primarily in tropical zones, especially near water sources. They tend to congregate in pairs, family groups, or small flocks of 30 birds or less. Very noisy, they vocalize often, whether resting in a canopy or traveling from one part of the forest to another.
Considered by many to be the class clown of the parrot world, Caiques are playful and always on the go. They love exploring new objects, which can include a newly purchased curio box or the hair of a new guest they have not met before. They can also react with unexpected fear or anger to new situations, objects, or even habitual practices such as being put down or back into their cage.
Likened to the scarlet macaw, Caiques are extremely intelligent, posing a challenge for their owners to keep them entertained and stimulated mentally. They do best when handled frequently by many different people and taken on a variety of regular "outings." Caiques may display territorial behavior, even toward people. Do not be intimidated. Removing the Caique prior to cleaning the cage will result in fewer confrontations.
Colorful, playful, and entertaining, Caiques can be noisy, so this may not be the best choice for apartment dwellers. Otherwise, these medium-sized charmers make captivating and loyal pets, generally selling for between $400-$500.
