\Horn"bill`\, n. (Zo["o]l.)
Any bird of the family {Bucerotid[ae]}, of which about sixty
species are known, belonging to numerous genera. They inhabit
the tropical parts of Asia, Africa, and the East Indies, and
are remarkable for having a more or less horn-like
protuberance, which is usually large and hollow and is
situated on the upper side of the beak. The size of the
hornbill varies from that of a pigeon to that of a raven, or
even larger. They feed chiefly upon fruit, but some species
eat dead animals.
