Description

The Yellow-casqued Hornbill, is found in the rainforest of coastal regions of West Africa. The Yellow-casqued Hornbill is one of the largest birds of the West African forest, with adults weighing up to 2 kg. They live mainly in the forest canopy, feeding on the ground 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 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. Recent research has shown that the birds respond in the same way to the alarm calls that Diana Monkeys, which live in the same areas, emit if they notice an eagle, and furthermore that they are able to distinguish the calls made by the monkey
