Yellow-Casqued Hornbill (Paperback)

High Quality Content by WIKIPEDIA articles! The Yellow-casqued Hornbill (Ceratogymna elata) is found in the primeval rain forest of coastal regions of West Africa, for example in Cote d'Ivoire. Yellow-casqued Hornbills are one of the largest birds of the forest, with adults weighing up to 2 kg. They live mainly in the forest canopy, feeding on the ground only rarely. They live in small family groups containing at least one adult male and female, with one or two immature birds, though they sometimes gather in larger flocks to exploit a major food supply such as an ant or termite nest. The birds are occasionally preyed upon by Crowned Hawk-eagles, and they respond to the presence of an eagle (sometimes indicated by its characteristic shriek) by mobbing, i.e. approaching it and emitting calls. Since the eagles depend on surprise to make a catch, this frequently causes them to leave the area.
