Great Hornbill

Great Hornbill

Scientific name: Buceros bicornis
Order: Coraciiformes

Also called Greater Indian Hornbill or Two-horned Calao

The Great Hornbill is a large bird, 95-120 cm (38-47 in) long, with a 152 cm (60 in) wingspan and a weight of 2.15-4 kg (4.7-8.8 lbs). The most prominent feature of the hornbill is the bright yellow and black casque on top of its massive bill. The casque is hollow and serves no known purpose (“tame” hornbills are known to enjoy having them scratched) although they are believed to be the result of sexual selection.

Male hornbills have been known to indulge in aerial casque butting flights. Females are smaller than males and have blue instead of red eyes. The male spreads the preen gland secretion which is yellow onto the primaries and bill to give them the bright yellow color.
