Systematics

The name Pseudastur was coined by Edward Blyth, but was first published in George Robert Gray's Index. ^{[1] [2] [3] [4]} The type species is the white hawk, Falco albicollis Latham, 1790.

The species were placed for some time in the genus Leucopternis , however this genus was found to be polyphyletic. In 2012 the American Ornithologists' Union split Leucopternis, placing the white hawk and its relatives under the old name Pseudastur. ^[5] The genus contains the following species:
