This hornbill occurs only in the forests of Narcondam Island. Males and females differ in head color, and fruit is its main food.
Males have a reddish-brown head, while females have a black head. The sexes therefore differ in head color, and the bill has the raised casque typical of hornbills.
It lives in the island's forest and feeds mainly on fruit, with small animals taken occasionally. It is described as resident on the island.
