The Blue and Yellow Macaw (Ara ararauna) lives in tropical forests and swampy areas up to 700 m above sea level and usually forms groups of more than 20 individuals, sometimes in mixed groups with macaws of other species. It is a typical inhabitant of the rainforest and also of other drier types of forest in South America, from eastern Panama and the island of Trinidad to Paraguay and southern Brazil, where they nest in hollow palm trunks.
The diet of the Blue and Yellow Macaw is frugivorous and granivorous: it eats grain, seeds, nuts and different types of fresh fruit. It reaches sexual maturity at the age of four or five, being a monogamous animal in which most couples remain together for many years, often a lifetime. They make their nests in tree holes and, more rarely, in rock holes.
The Blue-and-Yellow Macaw is highly prized as a cage bird and pet, so the over-catching to which it is subjected has caused it to disappear from many areas of its former range. It is included in Appendix II of the CITES Convention, which regulates the trade in species, as its greatest threat is trade, with years in which more than 50,000 individuals have been captured from the wild to be sold as pets.
