Arini
Psittacidae
The Arini are a diverse tribe of neotropical parrots, encompassing macaws and parakeets, distinguished by their vibrant plumage and long, pointed tails. They are found across the Americas, from the southern United States and the Caribbean to Mexico, Central America, and South America. This group includes some of the world's rarest birds, like the Spix's macaw, and the largest flying parrot, the hyacinth macaw, with several species now extinct.

About Arini
The Arini Tribe of Parrots
The Arini tribe represents a significant and diverse group of neotropical parrots, characterized by their striking, colorful plumage and distinctive long, tapering tails. This monophyletic clade encompasses well-known macaws and parakeets, the latter often referred to as conures in the pet trade. Their natural distribution spans a vast area of the Americas, from the southern United States and the Caribbean islands down through Mexico, Central America, and across South America.
Evolutionary History and Diversity
Molecular studies place the divergence of the Arini tribe from ancestral neotropical parrots in the late Paleogene period, approximately 30 to 35 million years ago. This long evolutionary history has resulted in a wide array of species, some of which are exceptionally rare, such as the Spix's macaw, which is now extinct in the wild with only a few individuals surviving in captivity. Conversely, the tribe also includes the hyacinth macaw, recognized as the largest flying parrot species in the world. The Arini are classified within the subfamily Arinae, which itself is part of the family Psittacidae, one of the three families of true parrots.
Conservation Concerns and Aviculture
The Arini tribe's history is marked by both remarkable biodiversity and significant conservation challenges. Several species and even entire genera are now extinct, and some species are critically endangered or extinct in the wild, with their survival dependent on captive breeding programs. The rarity of some species contrasts with the popularity of others as pets; for instance, the blue-and-yellow macaw and the sun conure are common and beloved companion birds. The presence of extinct species, some known only from subfossil remains, and the description of numerous hypothetical extinct Caribbean macaws underscore the vulnerability of this group to environmental changes and human impact.
