The Wreathed Hornbill’s casque is just a flattened wrinkled wreath at the base of the bill. It’s Javanese name “Anggang tahon” means “year bird”, because of the cross ridges on the beak. Belief that a new ridge forms every year is not valid, as more than one ridge may form in a year, and some front ridges may even drop off. Up to nine ridges have been counted, but the birds may live twenty years or more. More

Wreathed Hornbills are recorded in Malaysia, no nesting tree had ever been found due to their secretive nature and the inaccessible terrain. Belum-Temengor is the only place where all ten hornbill species occurring in Malaysia can be found together. “These hornbills are known to migrate long distances in search of fruiting resources and therefore require large contiguous areas of forest to survive,” said Yeap Chin Aik, Head of Conservation.

The wreathed hornbill is an omnivorous feeder, eating mostly fruit. The male, however, will feed small animals such as bats, reptiles, frogs, crabs, and insects to the females and developing chicks. It can find food from the treetops to the forest floor as well as in water. Habitat Hornbills generally live in Southeast Asia, but their population in slowly decreasing due to forest destruction.

Wreathed hornbill, and 12 of Oriental pied hornbill), of which 44 are currently standing. Twenty-four new nests have been found between 2004 and 2006. Forty-six nests were monitored in 2006, of which 2 were cut down in Papum Reserve Forest. The number of active nests was 32 (14 GH, 11 WH and 7 OPH) and chicks fledged successfully in 28 nests (87% success). More

The Wreathed Hornbill is a large (4-8 pounds) black bird with a yellowish tail, red eyes, and a long, thick beak topped with a small 'wreathed' casque with up to 9 ridges. The male has a bright yellow inflatable throat pouch, while the female's is blue. It is suggested that the casque, which has a spongy hollow core, may serve as a resonating chamber for its harsh barking call, as a form of interspecies recognition, and/or to convey health status.

the Plain-pouched wreathed hornbill, Aceros subruficollis was once considered conspecific with plicatus. . There is uncertainty about the species identification of a few of the older records. Five specimens were recorded as R. plicatus subruficollis. Kemp does not recognize this subspecies. It is unclear whether they were A. plicatus or A. subruficollis. These birds (studbook #1-5) did not reproduce, and have all died. Kemp lists this bird in the genus, Rhyticeros (in del Hoyaet al 2001). More

Wreathed HornbillGENERAL INFORMATION Other common names in use include: Bar-throated wreathed hornbill, Wreathed hornbill, and Northern waved hornbill. Kemp (1995) summarized the confusion in taxonomy of Rhyticeros subruficollis (Plain-pouched wreathed hornbill) which closely resembles the sympatric R. undulatus. From 1953 to about 1969, R. subruficollis was united with R. undulatus. This could have resulted in some misidentification of these two species in older records. More
