Hornbill

Hornbill, any bird of the Picarian family Bucerotidee, with twelve genera, containing fifty species, from the Oriental, Ethiopian, and Australian regions. They are for the most part large birds, with enormous bills, and in some cases' crests or helmets, with some outward resemblance to, but no close relationship with, the Toucans of the New World. They are chiefly fruit-eaters. The male plasters up his mate in her nest, feeding her and her young till nearly full grown, through a small slit left for the purpose.
