Sooty black bird with a large, heavy bill that is bone-white in males, dark in females. Some males have a bright white eyebrow, while others have an entirely black head. Females have reddish skin around the eye and a weaker, paler eyebrow stripe. Inhabits lowland mature forests. Travels singly, in pairs, or in small flocks, typically at lower levels in the forest than the large hornbills. Gives distinctly un-birdlike growling calls.

The description fits the bushy-crested hornbill, a fascinating bird species found in lowland mature forests. Their unique features, such as the bone-white bill in males and reddish skin around the eye in females, make them easily distinguishable. The growling calls add to their distinctiveness in the bird world.
