The Sri Lanka Grey Hornbills (Ocyceros gingalensis) is a hornbill and a widespread and common endemic resident breeder in Sri Lanka. Hornbills are a family of tropical near-passerine birds found in the Old World (Africa, Asia, and Europe).
The Sri Lanka Grey Hornbill is a gregarious bird found in forest habitats.
The Grey Hornbills is a large bird at 45cm in length. It has grey wings with black primary flight feathers, a grey back, and a brown crown. Its long tail is blackish with white sides, and the underparts are white. The long curved bill has no casque (a large display growth on the upper mandible of the bill).
Males and females look alike, although the male has a cream-colored bill, whereas the female’s is black with a cream stripe. Immature birds have dark grey upperparts, a cream bill, and a tail with a white tip. Its flight is slow and powerful.
Diet / Feeding
It feeds mostly on figs, although occasionally it eats small rodents, reptiles, and insects.
The female lays up to four white eggs in a tree hole blocked off during incubation with a cement made of mud, droppings, and fruit pulp. There is only one narrow aperture, barely wide enough for the male to transfer food to the mother and the chicks.
