The typical falconets, Microhierax, are a genus of bird of prey in the Falconidae family. They are found in southeast Asia and the smallest members of Falconiformes, averaging about 15 cm (5.9 in) in length and 35 g (1.2 oz) in weight. The smallest members of the genus are the relatively widespread black-thighed falconet, and the white-fronted falconet on the island of Borneo.
Species:
The first description by a European ornithologist of a falconet from this group was published by George Edwards in 1750, as "the little black and orange colour'd Indian hawk". It was from a specimen that had been collected in Bengal and sent to the King's physician, Dr Mead. In 1758 Carl Linnaeus used the illustration and description by Edwards to formally describe the species under the binomial name Falco cærulescens In 1760 the French naturalist Mathurin Jacques Brisson also used Edwards' publication to describe le Faucon de Bengale. Although the white collar was not mentioned, the English ornithologist Richard Bowdler Sharpe believed that this was the same species that we now call the collared falconet.
In 1824, Vigors proposed a new genus Ierax, writing "whoever has seen that beautiful species, the smallest of its race, F. cærulescens, Linn., now rendered familiar to us by the accurate and splendid illustrations of Dr. Horsfield, will at once acknowledge its separation from every other established genus of its family." Later authors rendered the name Hierax.
Sharpe coined the name Microhierax in 1874, from the Greek μικρόσ ἱεραξ meaning "tiny hawk". By this time, four species were known: M. cærulescens, M. fringillarius, M. melanoleucus, and M. erythrogenys. He lists Horsfield's specimen "Falco cærulescens" as being actually M. fringillarius, making the latter the type of the genus.
