Rhinoceros hornbills are found in Malaysia, Sumatra, Borneo and southern Thailand.
This species inhabits dense lowland forests with large trees suitable for nesting sites.
Rhinoceros hornbills are two and a half to three feet (75-90 cm) long; males are slightly larger than females.
They weigh four and a half to six and a half pounds (2.0-3.0 kg).
Feathers on the head, back, wings and breast are black with white feathers on the belly and a white tail with a black band through the middle.
They have a long curved bill with a casque on top. The bill and casque are ivory white tinged with yellow, with bright red coloring at the rear end of the casque.
What Does It Eat?
In the wild: Fruits, nuts, small animals including lizards and birds, and some insects.
At the zoo: Chopped apples, bananas, yams, grapes, bird pellets, bird of prey diet, and mice.
What Eats It?
The young rhinoceros hornbills are threatened by monkeys and snakes.
Rhinoceros hornbills live in monogamous pairs but they will congregate in groups at trees where food is abundant.
A month or more before mating, the male hornbill begins courting the female by bringing her food. Together the male and female select a nest hole high up in a tree and begin preparing the nest by plastering up the hole with mud and droppings. The male plasters the hole from outside and the female works from inside until only a small slit remains, creating a predator-proof nest. The female lays two to three white eggs and remains enclosed in the nest for three months incubating the eggs and caring for the chicks while the male delivers food to her and to the chicks. The chicks hatch after 39-45 days. Once the chicks have their first feathers, the female breaks out of the nest chamber and joins the male in providing food for the young. The chicks remain in the nest for about 80 days and then break through the opening. Rhinoceros hornbills are not sexually mature until they are about four years old. Lifespan in the wild is around 30 years and this species can live up to 33 years in captivity.
