This is a female Oriental pied hornbill, a medium-sized and highly adaptable hornbill. The female is distinguished from the male by the yellow, black and purple bill (and casque) and the dark eyes. The male has a significantly lighter bill and reddish eyes (hard to distinguish though). The species needs to eat a third of its weight every day to survive and is therefore a veritable omnivore. The favorite food is various kinds of fruit, especially figs, but this is supplemented with insects, small animals of various kinds, as well as reptiles as well as mammals and birds. Bird eggs also belong to the diet. A rather late discovery is that the Oriental hornbill (at least in Borneo) also hunts bats. They have learned to sit on watch outside bat caves at dusk and catch the bats in flight!
