Macaws are miniature to large, often colourful New World parrots. Of the  many different Psittacidae (true parrots) genera, six are classifed as  macaws: Ara, Anodorhynchus, Cyanopsitta, Primolius, Orthopsittaca, and  Diopsittaca. Previously, the members of the genus Primolius were placed  in Propyrrhura, but the former is correct as per ICZN rules.
Macaws are native to Mexico, Central America, South America, and formerly the Caribbean. Most species are associated with forest, especially rainforest, but others prefer woodland or savanna-like habitats.
