The great hornbill (Buceros bicornis), also known as the concave-casqued hornbill, great Indian hornbill or great pied hornbill, is one of the larger members of the hornbill family. It occurs in the Indian subcontinent and Southeast Asia. It is predominantly frugivorous, but also preys on small mammals, reptiles and birds.
Hornbills in the genus Buceros include some of the largest arboreal hornbills in the world, with the largest being the great hornbill. All the hornbills in this genus have a large and hollow bony casque on their upper beak that can be useful to scientists and bird watchers to recognise their age, sex and species. Their wingspan can be up to 1.8 ...
To complete the diet, they will regularly eat berries, fruits, nuts and eggs from other species. [4] Southern yellow-billed hornbill use their beaks as a pair of forceps. They will grasp their food between the tips and then toss it back in their throat where the short, stubby tongue will assist in swallowing the food. [2]
Female great hornbill feeding on figs. Fruit forms a large part of the diet of forest hornbills. Hornbills are omnivorous birds, eating fruit, insects and small animals. They cannot swallow food caught at the tip of the beak as their tongues are too short to manipulate it, so they toss it back to the throat with a jerk of the head.
The entrance to the nest retains a narrow aperture through which the female voids excreta and receives food from the male. The male brings all the food needed for the female and the young. Berries, insects, small rodents and reptiles are included in the diet. Males tap the tree to beckon the female on arriving with food. [14]
The wreathed hornbill is a monotypic taxon and is widely recognized as a member of Rhyticeros, the genus of hornbills with low wreathed casques. [6] Analysis of the mitochondrial genomes of eight hornbill species revealed that the wreathed hornbill is closely related with Aceros and the Visayan hornbill (Penelopides panini). [7]
The BNHS logo is the great hornbill, inspired by a great hornbill named William, who lived on the premises of the Society from 1894 until 1920, during the honorary secretaryships of H. M. Phipson until 1906 and W. S. Millard from 1906 to 1920. [10] The logo was created in 1933, the golden jubilee year of the Society's founding.
The genus Bucorvus was introduced, originally as a subgenus, by the French naturalist René Lesson in 1830 with the Abyssinian ground hornbill Bucorvus abyssinicus as the type species. [ 4 ] [ 5 ] The generic name is derived from the name of the genus Buceros introduced by Carl Linnaeus in 1758 for the Asian hornbills where corvus is the Latin ...
