The White-breasted Hawk occurs in forests from southern Mexico into northern Central America. This entry follows sources that treat A. chionogaster as a species, while the 2010 life-history paper says its taxonomic status was unresolved.
Adults have slate-grey upperparts, white underparts and dark bands on the tail; juveniles are brown above.
At study sites in Honduras and El Salvador, both parents built nests in pine trees; breeding was recorded from December to April.
An extinction-risk assessment has not been added yet.
