A fairly large bird of lowland and foothill forest on Mindanao and neighboring islands. Small for a hornbill. Bill fairly short with black bands. Has a shaggy crest at the back of the head, black wings, a black base and tip to the tail with a buffy central part, and bluish bare skin around the face and chin. Male has pale underparts and head with a black cheek, while female is entirely black with deeper blue facial skin. Female is similar to female Writhed Hornbill, but smaller, and lacks the red bill. Voice is a short, medium-pitched honk, reminiscent of a squeaky toy.
