The Bucerotidae include about 55 living species, though a number of cryptic species may yet be split, as has been suggested for the red-billed hornbill. Their distribution includes Sub-Saharan Africa and the Indian subcontinent to the Philippines and the Solomon Islands, but no genus is found in both Africa and Asia.
The great hornbill was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae.He placed it with the rhinoceros hornbill in the genus Buceros and coined the binomial name Buceros bicornis.
The red-billed hornbills are a group of hornbills found in the savannas and woodlands of sub-Saharan Africa.They are now usually split into five species, the northern red-billed hornbill (Tockus erythrorhynchus), western red-billed hornbill (T. kempi), Tanzanian red-billed hornbill (T. ruahae), southern red-billed hornbill (T. rufirostris) and Damara red-billed hornbill (T. damarensis), but ...
Female great hornbill Hornbills are birds in the families Bucerotidae and Bucorvidae. There are currently 62 extant species of hornbills recognised by the International Ornithologists' Union, two in Bucorvidae and 60 in Bucerotidae. Many species of fossil hornbills are known from the Miocene onwards; however, their exact number and taxonomy are unsettled due to ongoing discoveries. Conventions ...
The blue-banded toucanet is 40 to 44 cm (16 to 17 in) long and weighs 173 to 257 g (6.1 to 9.1 oz). The sexes are alike. Adults have a bluish horn-colored bill. Their plumage is mostly green with a red rump, white throat, a diffuse blue band across the chest, and greenish-yellow undertail coverts.
The red-billed toucan and Cuvier's toucan, which differ principally in the bill colour, interbreed freely wherever they meet and therefore now merit only subspecies status. Some authorities consider the Inca toucan to represent a stable hybrid population between the other two subspecies and do not recognize it as a separate subspecies.
The rhinoceros hornbill (Buceros rhinoceros) is a large species of forest hornbill (Bucerotidae).In captivity it can live for up to 35 years. It is found in lowland and montane, tropical and subtropical climates and in mountain rain forests up to 1,400 metres in Borneo, Sumatra, Java, the Malay Peninsula, Singapore, and southern Thailand.
