Parrots, also known as psittacines (/ ˈ s ɪ t ə s aɪ n z /), [1] [2] are the 402 species of birds that make up the order Psittaciformes, found in most tropical and subtropical regions, of which 387 are extant.
A parrot is found on the flag of Dominica and two parrots on their coat of arms. [133] The St. Vincent parrot is the national bird of St. Vincent and the Grenadines, a Caribbean nation. [134] Sayings about parrots colour the modern English language. The verb "parrot" in the dictionary means "to repeat by rote".
The tree is based on the work by Leo Joseph and collaborators published in 2012 but with the choice of families and the number of species in each family taken from the list maintained by Frank Gill, Pamela Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC), now the International Ornithologists' Union.

Vinaceous-breasted amazons are thought to prefer parana pine trees, and have been shown to prefer forest fragments or isolated trees, [24]: 21–22 while Tucumán amazons nest at higher elevations than other amazon parrots, mostly in Blepharocalyx trees, within the cloud-forest.
However, the tree of the parrot family now has been reorganized under the superfamily Psittacoidea: family Psittacidae has been split into three families, tribes Strigopini and Nestorini split out and placed under superfamily Strigopoidea and a new monotypic superfamily Cacatuoidea created containing family Cacatuidae.

Subsequent molecular studies indicate that the earliest offshoot from the original parrot ancestors were the New Zealand parrots of the family Strigopidae, and following this the cockatoos, now a well-defined group or clade, split off from the remaining parrots, which then radiated across the Southern Hemisphere and diversified into the many ...
Like others of its family, the male Raggiana bird-of-paradise has elaborate breeding plumage used to impress females. [215] 95 per cent of bird species are socially monogamous. These species pair for at least the length of the breeding season or—in some cases—for several years or until the death of one mate. [216]
Plate XLIII from Samuel Pepys's hand-coloured copy of Francis Willughby's 1678 Ornithology [1]. Early scientific works on birds, such as those of Conrad Gessner, Ulisse Aldrovandi and Pierre Belon, relied for much of their content on the authority of the Ancient Greek philosopher Aristotle and the teachings of the church, [2] [3] and included much extraneous material relating to the species ...
