Red-tailed hawk [SEP] Taxonomy
The red-tailed hawk was formally described in 1788 by the German naturalist Johann Friedrich Gmelin under the binomial name "Falco jamaicensis". Gmelin based his description on the "cream-coloured buzzard" described in 1781 by John Latham in his "A General Synopsis of Birds". The type locality is Jamaica. The red-tailed hawk is now placed in the genus "Buteo" was erected by the French naturalist Bernard Germain de Lacépède in 1799. The red-tailed hawk is a member of the subfamily Buteoninae which includes about 55 currently recognized species. Unlike many lineages of accipitrid, which seemed to have radiated out of Africa or south Asia, the Buteoninae clearly originated in the Americas based on fossil records and current species distributions (more than 75% of the extant hawks from this lineage are found in the Americas).
