Concave Casqued Hornbill or Great Hornbill is a species of hornbill in the family Bucerotidae.
Concave Casqued Hornbill or Great hornbills are social birds that live in small groups of 2-40 individuals. They are usually seen in small parties, with larger groups sometimes aggregating at fruit trees.
Concave Casqued Hornbill or Great hornbills are monogamous and form long-lasting pair bonds. During the breeding season which takes place from January to April, these birds become very vocal. They make loud duets, beginning with a loud “kok” given about once a second by the male, to which the female joins in. The pair then calls in unison, turning into a rapid mixture of roars and barks.
The female Concave Casqued Hornbill builds a nest in the hollow of a large tree trunk, sealing the opening with a plaster made up mainly of feces and leaves. She remains in the nest, relying on the male to bring her food, until the chicks are half-developed. During this period the female undergoes a complete molt.
The clutch consists of one or two eggs, which she incubates for 38-40 days. The chicks are altricial; they are hatched helpless, have no feathers, and appear very plump. The female usually leaves the nest before the young fledge and seals the entrance again.
Both parents continue to feed their offspring until they fledge 72-96 days after hatching and become fully independent.
