Psittacinae (Afrotropical parrots, African parrots, or Old World parrots [1]) is a subfamily of parrots, native to sub-Saharan Africa, which include twelve species and two extant genera.
Range maps are provided wherever possible; if a range map is not available, a description of the bird's range is provided. Ranges are based on the IUCN red list for that species unless otherwise noted. All extinct species listed went extinct after 1500 CE (recently extinct [20]), and are indicated by a dagger symbol "†".
The family Psittacidae or holotropical parrots is one of three families of true parrots.It comprises the 12 species of subfamily Psittacinae (the Afrotropical parrots) and 167 of subfamily Arinae (the New World or Neotropical parrots) including several species that have gone extinct in recent centuries.
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.
Pacheco's disease is a highly infectious and acute bird disease caused by a species of herpesvirus, Psittacid alphaherpesvirus 1 (PsHV-1). [1] [2] All psittacine species are susceptible to Pacheco's disease, mainly those in zoological collections and aviaries in any geographic regions. [1]
Psittacopasseres is a taxon of birds consisting of the Passeriformes (passerines, a large group of perching birds) and Psittaciformes (). [3] Per Ericson and colleagues, in analysing genomic DNA, revealed a lineage comprising passerines, psittacines and Falconiformes. [4]
