The caiques are species of parrots in the genus Pionites. They are relatively small and stocky, with a short, square tail and very bright colors. Their typical weight is 150–170 grams. They can live up to 40 years. They are endemic to the Amazon Basin in South America, with the black-headed north of the Amazon River, and the white-bellied south. They 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. The term "caique" is primarily used in aviculture, with ornithologists preferring "parrot" to describe these species.
