[edit] Taxonomy
A member of the Hornbill family Bucerotidae and one of the three species of the genus Ocyceros, sometimes also placed in Tockus. Sri Lanka Grey Hornbill Ocyceros gingalensis is sometimes included in this species. Monotypic.
[edit] Habitat
Broadleved evergreen and moist deciduous forest. Sometimes in gardens and plantations.
[edit] Behaviour
Usually found in the middle storey in small groups. Sometimes together with other frugivorous species like green pigeons or bulbuls. Often quite inconspicuous and allows close approaching.
Diet includes fruits such as figs, though it also eats small rodents, reptiles and insects.
Up to 4 white eggs are laid in a tree hole, which is blocked off during incubation with a cement made of mud, droppings and fruit pulp. There is only one narrow aperture, just big enough for the male to transfer food to the mother and the chicks.
