Red-Billed Hornbill

Thin red bill and pale head distinctive, crown and nape dark gray, neck and face white, back sooty brown with white stripe down center, underparts white, primaries black with white spots, tail black. Circumorbital and throat skin creamy yellow to pale pink. 3 subspecies. Males and females similar but males slightly larger.
Obtains almost all food on the ground while running about. Feeds largely on insects - beetles, grasshoppers, termites, ants, fly larvae. Also takes geckos, birds' eggs and nestlings and scavenges dead rodents.
Usually found in pairs or small family parties, but during the dry season may congregate in flocks of several hundred at good feeding areas, such as around water holes. They are territorial and will defend their territories against their own species, but not other species, so that several species of hornbill may have overlapping territories. Birds move to feeding areas early in the morning, but usually return to a regular roost site within their territories at night. They roost in a tree close to the trunk or large branch. Like all hornbills except the large ground hornbills of Africa, Red-billed Hornbills nest in holes in trees where the female is sealed up for two to three months while she incubates the eggs and feeds the young with insects brought by the male. The female lays 3-5 eggs which she incubates from 23-25 days. The female molts and re-grows her feathers during incubation. She breaks out of the nest when the eldest chick is 21-22 days old. The chicks reseal the entrance alone using their droppings and food remains. Chicks fly well on first emergence from nest, never returning. They may remain with their parents for 6 months.
