And a female bird would only enter the cavity and seal herself in after copulation. This would be a distinct possibility, considering that both are females. But there has not been any attempt of the Rhinoceros sealing herself inside the cavity. There is a report of someone seeing the Rhinoceros entering the cavity, to move out soon after. The pair has been visiting the tree during February to May, as this is supposed to be the breeding period. The Great is perching on the tree trunk below, waiting for her decision. The image on the left shows the Rhinoceros, with her head inside the cavity, checking the interior. There was always a pair, probably breeding nearby, that followed the hornbills around. In the image below you can see a Greater Racket-tailed Drongo ( Dicrurus paradisus) harassing the Rhinoceros. Only then would the Rhinoceros fly off to check the potential nest cavity. Possibly, this was to reassure her that “he” would keep on feeding her should she be sealed up in the cavity during egg incubation and after (should this happen). “He” would then fly back to join the Rhinoceros on a nearby branch and delicately fed the latter with a fig. The pair would meet in the morning and/or evening and the Great (above right, taking on the role of a male) would always check on the cavity. However, through the generosity of Meng and Melinda Chan, we are able to showcase here more of what actually happened around the old albizia tree ( Paraserianthes falcataria). rhinoceros), both female, at Eng Neo has already been told. Both usual tie-ups for life.The courtship behaviour of a Great ( Buceros bicronis) and a Rhinoceros Hornbill ( B. Sometimes, vocals consist of low, resonant calls, more often than not in series: either a single-syllabled “rohh” or a disyllabic “roh-ow.” Normally, Rhinoceros Hornbill call during their territory defends from other breeding pairs. The male bird distinguishes the deep forceful huk, huk, notes while the female blessed with hak hak notes. 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. Hence, these are the main threats the hornbill is being uplisted to vulnerable from near threatened on the IUCN Red List in 2018.īeak – Rhinoceros Hornbill beak is a marvel of God, versatile, and frivolous. 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. However may also prey on little insects, rodent, small reptile, eat arthropods, lizards, frogs, bird eggs, and smaller birds.īreeding – The female rhinobill has faith in the male to deliver her everything during incubating and raising chicks. The eyes of the male bird are normally red with black rims and white with red rims in the female bird.įood – The rhinobill preferred diet is fruit. 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. Weight – The rhinoceros hornbill (Buceros rhinoceros) weighing around 2,450 to 2,980 g, however, females’ weight is a little less to around 2,020 to 2,350 g. Size – The average size of a large rhinoceros bird is approximately 30 to 35 inches long. The rhinoceros bird can find a mountain of the rainforest up to 1,200 meters in Sumatra, Java, Singapore, Malay Peninsula, Borneo, and Southern Thailand. Where it Lives – The Rhinoceros Hornbill bird mostly found in tropical and subtropical climates of lowland and montane. The colorful Rhinoceros Hornbill is a large species (80 to 90 cm) of forest Hornbill. Life – A rhinoceros hornbill can live up to 30 to 35 years.
