Hawks and Eagles (Accipitridae)
Bicolored Hawk (Accipiter bicolor) - HBW 2, p. 161
French: Épervier bicolore
German: Zweifarbensperber
Spanish: Gavilán Bicolor
Other common names: Spotted Hawk (guttifer)
Taxonomy: Sparvius bicolor Vieillot, 1817, Cayenne.
Normally considered to include A. chilensis as a race, but differs in ecology, especially in habitat preferences; also closely related to A. cooperii and A. gundlachi, and these four form a superspecies. Race guttifer has been considered full species; alternatively a race of A. chilensis, but isolated range of A. chilensis and intergradation of guttifer with A. b. pileatus suggest guttifer closer to A. bicolor. Race schistochlamys of W Ecuador incorporated in nominate. Four subspecies currently recognized.
