Distribution: Neotropical. Highlands of Central America from southern MEXICO (Chiapas, eastern Oaxaca) south through interior highlands of GUATEMALA, HONDURAS, and EL SALVADOR to north-central NICARAGUA. more....

Subspecies: Monotypic.

Taxonomy: Several recent authors (e.g., del Hoyo et al. 1994) have regarded the Neotropical sharp-shin taxa as representing full species, forming a superspecies with A. striatus, although a definitive study on these relationships has not yet been undertaken. The White-breasted Hawk was treated as a race of the South American A. erythronemius (Hellmayr and Conover 1949), or of A. striatus (Storer 1952, Brown and Amadon 1968, Stresemann and Amadon 1979, Ferguson-Lees and Christie 2001). Bildstein (2004) suggested that this species may have derived from the allopatric Sharp-shinned Hawk as a result of "migration dosing." more....

Movements: Non-migratory (Bildstein and Zalles 2005).

Habitat and Habits: Occurs in middle and montane elevations, mostly in pine-oak woodlands, but occasionally in broad-leafed cloud forest, montane rainforest, or semi-open areas, primarily above 600-900 m (Monroe 1968, Land 1970, Ridgely and Gwynne 1989). Behavior is like that of the Sharp-shinned Hawk.

Food and Feeding Behavior: Feeds on small birds.

Breeding: Jenner (2008) and several colleagues located seven nests at Cerro El Pericón, El Salvador in 2008. The species has a long breeding period there, with pairs becoming established in October and nest construction occurring mainly in December. Eggs are laid in March, and the chicks fledge in June and remain in the vicinity of the nest into July. Jenner (op cit.) found an unusually high nesting density in an area of pine forest, with 5.1 nests/km² and only a space of 580 m between neighboring nests. more....

Conservation: This species is fairly common in portions of its limited range, but it deserves more detailed study because of ongoing deforestation in this region. Categorized as a species of "Least Concern" by BirdLife International (2008). more....
