Buceros bicornis, sexual differences in the colouring of the casque, beak, and mouth in. Buceros corrugatus, sexual differences in the beak of.
In Buceros corrugatus, the whole beak and immense casque are coloured more conspicuously in the male than in the female; and "the oblique grooves upon the sides of the lower mandible are peculiar to the male sex." The head, again, often supports fleshy appendages, filaments, and solid protuberances. These, if not common to both sexes, are always confined to the males.
