Rhinoceros Hornbill

Buceros rhinoceros

Buceros rhinoceros is one of the largest hornbills, adults being approximately the size of a swan, 110–127 cm long and weighing 2–3 kg. It is found in lowland and montane tropical/subtropical rain forest up to 1,400 metres altitude in Borneo, Sumatra, Java, the Malay Peninsula, Singapore and southern Thailand.
Juvenile Rhino Hornbill A flock of Rhinoceros Hornbills (around 20) of mixed sex and age group were looking for some ripe fruits on this Spiky Fig tree. Named the Rhinoceros Hornbill for it's large "horn" that points upwards like a rhinoceros. This is one of the largest hornbill species so it is large enough to swallow the spiky fig whole. However, these hornbills will carefully toss and mash the fruit until most of the hairy skins fall out and the remaining spikes are buried into the flesh and it would go smoother down the throat. Such precision control they have on their large beak. Epiphytic fig like this spiky fig depends on long-distance flying canopy birds like these hornbills to disperse its seeds onto another host tree far away. Wild figs are a very important food source to hornbills. This is recorded during our few days observation to document the ecological value of this fig species as an important species for our reforestation projects.

Like most other hornbills, the male has orange or red eyes, and the female has whitish eyes. This bird has a mainly white beak and casque, but there are orange places here and there. It has white underparts, especially to the tail.

Reproduction

The courtship and bonding of these birds are critical, as the female must trust the male to provide her with everything when she is incubating and raising chicks.

These hornbills lay their eggs inside tree trunks and the females stay inside with the eggs and then with the chicks, while the male will bring them food. After the eggs are laid, the male collects mud and the pair pack that mud, along with food and feces, to "mud-up" the tree cavity entrance.

his creates a very small hole, only large enough for the male to feed the female and for the female to defecate out of the hole. Once the babies are fully feathered and old enough to leave the nest, the female and male chip away the dry mud so the chicks can get out.

Predators

The Rhinoceros Hornbill faces a number of threats, including habitat loss and hunting for its meat, feathers and for its casque, which can be carved into an ornament.
