Black-chested Buzzard-eagle
Buteo melanoleucus
Status: Lower risk
Population Trend: Unknown.
Other Names: Black Buzzard-eagle, Black-chested Eagle, Black-breasted Buzzard, Black-breasted Buzzard-eagle, Black-chested Buzzard Eagle, Black-chested Eagle-buzzard, Buteo fuscescens, Chilean Buzzard, Geranoaetus melanoleucus, Gray Eagle, Gray Eagle-buzzard, Gray Buzzard-eagle.
Distribution: Neotropical. Andes of COLOMBIA south to northern ARGENTINA and TIERRA DEL FUEGO.
Subspecies: 2 races. G. m. australis: COLOMBIA and northwestern VENEZUELA (Mérida) south through the entire length of the Andes to CHILE, Patagonian ARGENTINA, and TIERRA DEL FUEGO; G. m. melanoleucus: Southeastern BRAZIL to PARAGUAY, URUGUAY, and northeastern ARGENTINA.
Taxonomy: The molecular studies of Riesing et al. (2003) indicated that this species is best included in the genus Buteo, rather than the separate monotypic genus Geranoaetus, where most authors have placed it in recent decades. The species was formerly called Buteo fuscescens by various authors, including Wetmore (1933), Hellmayr and Conover (1949) and Johnson (1965), but (Bierregaard 1994) thought it was more closely related to Buteogallus and Leucopternis than to Buteo. Clark and Schmitt (2006) also agreed that ths species is a buteo, based on morphological characters, and they recommended that its vernacular name be changed to "Black-breasted Buzzard."
Movements: Partial migrant.
Habitat and Habits: Middle level elevations and montane regions, even above treeline; descends to coast in Peru and to lowlands in southeastern portion of range. Prefers open dry habitats in rugged terrain. Soars incessantly, often in pairs. Also perches on rocky cliffs or ground, but seldom in trees.
Food and Feeding Behavior: Feeds mostly on small mammals, birds, and carrion; also raids bird nests to feed on nestlings.
Breeding: Bulky stick nest placed on rock, ledge, or cliff. Eggs 2-3, white.
Conservation: Generally fairly common throughout much of its extensive range, except in the most northern portion (Fjeldså and Krabbe 1990). Categorized as a species of "Least Concern" by BirdLife International.
