Brownish, medium-sized hornbill. Male is dusty brown above and rusty-colored below, with a pale bill and blue-gray skin around the eye. Female is similarly patterned, but is duller overall, with a dark bill. Very similar to closely related Brown Hornbill, with which it overlaps in the far northern edge of its range; look for a darker brown throat in the male and a black (instead of white) bill in the female. Gives loud whistled screams.
