One of the larger members of the hornbill family, Buceros bicornis known commonly as Great hornbill is usually seen in small numbers and are found in the forest from lowlands to 1,500 m above sea level.

The males and females are similar except that the irises of males are red while those of females are white (Jeyarajasingam & Pearson, 2012). The male has black and white plumage with some white parts washed yellow. This is due to the oily exudation produced by the uropygial gland when the bird is preening. It rubs its head against the gland situated at the upper base of the tail and transfers this oil to its plumage.

Generally, they feed on fruits, but they also feed on small mammals, birds, small reptiles, and insects. The biggest threat to this species is habitat destruction, and particularly the removal of the old-growth trees that these birds require for nesting (IUCN, 2017).
