gavião-caranguejeiro-negro Buteogallus anthracinus

An aptly-named entirely black hawk with broad wings and short tail with a distinct white band. Flight feathers are slightly paler and it has long yellow legs and yellow on the base of the bill. Immature birds are streaky brown with dark moustache and pale eyebrow. Typically found in woodlands near water where it hunts; shows an affinity for cottonwood trees at the northern end of its range.
