Male and female black-casqued hornbill differ in physical appearance and are therefore an example of sexual dimorphism. The males are larger, have black feathers on their head, and have a larger casque. The females have brown hood of feathers.[4]
The black-casqued hornbill is known for its intelligence.[3] They are most commonly found in pairs, but small groups of up to 5 are also somewhat frequent.[3] They feed on insects and at least 19 species of fruit.[3]
