The most distinctive feature of the hornbills is the heavy bill, supported by powerful neck muscles as well as by the fused vertebrae. [3] The large bill assists in fighting, preening, constructing the nest, and catching prey. A feature unique to the hornbills is the casque, a hollow structure that runs along the upper mandible. In some species ...
The great hornbill is a large bird, 95–130 cm (37–51 in) long, with a 152 cm (60 in) wingspan and a weight of 2 to 4 kg (4.4 to 8.8 lb). The average weight of 7 males is 3 kg (6.6 lb) whereas that of 3 females is 2.59 kg (5.7 lb). [ 9 ]
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 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 ...

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.
The southern ground hornbill is an obligate cooperative breeder, with each breeding pair always assisted by at least two other birds. Experiments in captivity [20] have found that birds without six years experience as helpers at the nest are unable to breed successfully if they do become breeders. This suggests that unaided pairs cannot rear ...
