French: Buse à gros bec
German: Wegebussard
Spanish: Busardo Caminero
Other common names: Insect Hawk, Tropical Broad-winged Hawk, Large-billed Hawk
Taxonomy: Falco magnirostris Gmelin, 1788, Cayenne.

Many more races have been recognized: race griseocauda includes argutus, direptor, xantusi and petersi; race magnirostris includes insidiatrix and ecuadoriensis; race occiduus includes inca; and race pucherani includes gularis.
