The caiques /kɑːˈiːk/ are species of parrots in the genus Pionites. They are relatively small and stocky, with a short, square tail. Due to their very bright, pure colors they are considered among the most beautiful parrot species in the aviculture business. Their typical weight is 150–170 grams. They can live up to 40 years. They are endemic in the Amazon Basin in South America, with the black-headed north of the Amazon River, and the white-bellied south. They are endangered and are listed on Appendix 2 of CITES as a species of least concern. They generally prefer forested areas and subsist on fruit and seeds. Caiques are generally canopy dwellers, spending most of their time in the tops of trees, foraging and playing. Caique wing feathers produce a distinctive whirring sound in flight. They are highly vocal.
