![]() On the top of the golden-yellow beak, cumbersome casque (hollow helmet-like structure) supports amplifying their calls. The bird performs different things with its beak such as chewing food, nest building, sealing the nest, feeding the baby. Beak – Rhinoceros Hornbill beak is a marvel of God, versatile, and frivolous. Hence, these are the main threats the hornbill is being uplisted to vulnerable from near threatened on the IUCN Red List in 2018. Therefore, poachers easily find the rhinobill and shot them. Also, the loss of big trees due to habitat destruction is another reason for declining the number of hornbills. Threats – The rhinoceros hornbill encounters many different threats, including hunting for its meat, its skull & feathers, and loss of rainforest habitats. ![]() Once the baby birds are fully feathered and big in size to leave the nest, both parents chip away the dry mud to let the chicks out. The female bird lays 1 or 2 eggs, usually takes 36-to-46 days to incubate and the baby fledges 85-to-96 days after the eggs are laid. Usually, they leave a small hole in it, just big enough for the male passes through a vertical slit, to feed the female and chicks. Once the nest ready and eggs are laid in them, the male hornbill collects mud, and both pack that mud with food and feces, to seal the entrance to the tree cavity. Nest – Rhinoceros Hornbill normally makes their nest inside the hollow tree trunks. Female stays inside the nest with the eggs and after the incubations, the male’s responsibility to bring the food for her and the chicks. Breeding – The female rhinobill has faith in the male to deliver her everything during incubating and raising chicks. However may also prey on little insects, rodent, small reptile, eat arthropods, lizards, frogs, bird eggs, and smaller birds. Food – The rhinobill preferred diet is fruit. The eyes of the male bird are normally red with black rims and white with red rims in the female bird. The big bill and casque are habitually orange to red, from preen oil rubbed on from the preen gland above the tail. Plumage – The rhino bill plumage is mainly black, with white legs, and vent, and a black band with whitetail. It is also hunted for its bill and tail feathers, which are used in ceremonial dress, and is captured for trade and food.The Rhinoceros Hornbill Facts – The male bird distinguishes the deep forceful huk, huk, notes while the female blessed with hak hak notes. Reduction in numbers in many areas is due to the cutting of forests for agriculture and timber. Status: Currently a CITES Appendix II species, and categorized as near threatened on the IUCN Red List. Habitat/range: Rhinoceros hornbills live in extensive areas of primary evergreen and tall secondary forest (up to 4,593 feet or 1,400 m) in Thailand, Malaysia and Sumatra. The female will molt during this time period in the nest. Chicks emerge after 39-51 days and fledge in 78-80 days. One or two eggs are usually incubated 37-46 days. This protects the female and eggs from predators. Together the pair “wall” the female in the nest with mud the male leaves a small hole through which he uses his long beak to pass food to the female (and hatchlings). Reproduction: The female nests in natural cavities 30- 49 feet (9-15 m) up in tall trees. ![]() Rounded wings make flight more difficult and extremely noisy (“whooshing” wing-beats sound like an overloaded locomotive). This loud, harsh vocalization can often be heard between pairs and often have a sharper note used for flight take- offs. ![]() They are fairly easy to locate due to their habits, size and sounds.ĭiet: Rhinoceros hornbills mainly feed on fruits (preferably figs) but also eat arthropods, lizards, tree frogs, and bird eggs.Ĭommunication: The large, bony, light-weight casque amplifies the honking squawk Rhinoceros hornbills use to communicate. Males often feed females, even during non-breeding seasons. ![]() Females weigh 4.5-5.1 pounds (2-2.3 kg).īehavior: During non-breeding seasons, rhinoceros hornbills can be seen foraging in pairs or small flocks. Size: Rhinoceros hornbills are very large birds. In addition to being smaller in size, female Rhinoceros hornbills have smaller casques with no black base and their red-rimmed eyes are white. The natural color of the casque and bill is creamy white but they become cosmetically colored by rubbing them against a gland beneath the tail, which exudes an orangish- red oil. Eyes of the male are red with black rims. The large bill and casque are yellow and orange-red (black at the base in males) bill is slightly recurved with upturned casque atop the base of the bill. Description: The head, back, breast and wings of the rhinoceros hornbill are black thighs and vent are white. ![]()
