The data place most of the diversification of psittaciformes around 40 Mya, after the separation of Australia from West Antarctica and South America. [ 2 ] [ 4 ] Divergence of the Psittacidae from the ancestral parrots resulted from a common radiation event from what was then West Antarctica into South America, then Africa, via late Cretaceous ...
Parrots (Psittaciformes), also known as psittacines (/ ˈ s ɪ t ə s aɪ n z /), [1] [2] are birds with a strong curved beak, upright stance, and clawed feet. [ a ] They are classified in four families that contain roughly 410 species in 101 genera , found mostly in tropical and subtropical regions.
The following cladogram shows how the family Psittaculidae relates to the three other families in the order Psittaciformes.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 ...
The true parrots are distributed throughout the tropical and subtropical regions of the world, mostly in the Southern Hemisphere, covering many different habitats, from the humid tropical forests to deserts in Australia, India, Southeast Asia, sub-Saharan Africa, Central and South America, and two species, one extinct (the Carolina parakeet), formerly in the United States.
A cockatoo is any of the 21 species of parrots belonging to the family Cacatuidae, the only family in the superfamily Cacatuoidea. Along with the Psittacoidea (true parrots) and the Strigopoidea (large New Zealand parrots), they make up the order Psittaciformes.
The largest known species of Psittaciformes, which comprises the modern parrots and cockatoos, it is estimated to have been around one meter in height, with a body mass of seven kilograms, and presumed to have been flightless, terrestrial and perhaps arboreal.
All species show considerable sexual dimorphism.These species have traditionally been placed in the genus Psephotus along with the red-rumped parrot, but a molecular study analysing nuclear and mitochondrial DNA found that the red-rumped parrot was an early offshoot in a clade of several genera of broad-tailed parrot, with the other species nested deeply within.
