A fairly large bird of lowland and foothill forest on Luzon and neighboring islands. Small for a hornbill. Bill fairly short with black bands. Has black wings and rump, a black tail with a pale band, and bare skin with a blue tinge around the eye and chin. Male has pale underparts and head with a black cheek, while female is entirely black. The only other hornbill in range is Rufous Hornbill, but Luzon lacks the red bill. Voice is a sharp, medium-pitched nasal honk, reminiscent of a squeaky toy.
