Psittacine Siadneovirus D
Psittacinae is a subfamily of Afrotropical or Old World parrots, native to sub-Saharan Africa, which include twelve species and two extant genera. Among the species is the iconic grey parrot. The ''Poicephalus'' are usually green birds with different colored heads; the larger ''Psittacus'' are light grey with red tails. African parrots (at least the grey parrot) have been known in Europe since Roman times. The African parrots, unlike their Neotropical cousins, are polyphyletic: ''Agapornis'' of Africa and Madagascar was found to be the sister group to '' Loriculus'' of Australasia and Indo-Malayasia and together they clustered with the Australasian ''Loriinae'', ''Cyclopsittacini'' and '' Melopsittacus''. ''Poicephalus'' and ''Psittacus'' from mainland Africa formed the sister group of the Neotropical ''Arinae'' and '' Coracopsis'' from Madagascar and adjacent islands may be the closest relative of '' Psittrichas'' from New Guinea.

Constantine Samuel Rafinesque
Constantine Samuel Rafinesque-Schmaltz (; October 22, 1783September 18, 1840) was a French 19th-century polymath born near Constantinople in the Ottoman Empire and self-educated in France. He traveled as a young man in the United States, ultimately settling in Ohio in 1815, where he made notable contributions to botany, zoology, and the study of prehistoric earthworks in North America. He also contributed to the study of ancient Mesoamerican linguistics, in addition to work he had already completed in Europe. Rafinesque was an eccentric and erratic genius. He was an autodidact, who excelled in various fields of knowledge, as a zoologist, botanist, writer and polyglot. He wrote prolifically on such diverse topics as anthropology, biology, geology, and linguistics, but was honored in none of these fields during his lifetime. Indeed, he was an outcast in the American scientific community whose submissions were rejected automatically by leading journals. Among his theories were th ...

Agapornis
Lovebird is the common name for the genus ''Agapornis'', a small group of parrots in the Old World parrot family Psittaculidae. Of the nine species in the genus, all are native to the African continent, with the grey-headed lovebird being native to the African island of Madagascar. Social and affectionate, the name comes from the parrots' strong, monogamous pair bonding and the long periods which paired birds spend sitting together. Lovebirds live in small flocks and eat fruit, vegetables, grasses, and seeds. Black-winged lovebirds also eat insects and figs, and black-collared lovebirds have a special dietary requirement for native figs, making them difficult to keep in captivity. Some species are kept as pets, and several coloured mutations have been selectively bred in aviculture. The average lifespan is 20 to 30 years. Description Lovebirds are in length, up to 24 cm in wingspan with 9 cm for a single wing and in weight. They are among the smallest parrots, char ...
