The commonest Asian Hornbill.

Taxonomy

Forms a superspecies with Malabar Pied Hornbill and Palawan Hornbill. Was long considered to be conspecific with Malabar Pied Hornbill and the two species have been confused several times, leading to synonymy of common and scientific names.

Subspecies convexus may be elevated as "Sunda Pied Hornbill", A. convexus.

Clements recognises the following subspecies [1]:

Habitat

Open habitat such as forest edge, clearings and secondary forest. Occurs up to 700m.

Behaviour

Diet

Feeds mainly on fruit, takes also small animals.

Breeding

Breeds in pairs. Nests in a natural cavity in a tree. The incubating females are sealed into tree hole nests with mud, leaving only a small aperture through which food can be passed by the male. When the young are hatched the female breaks out but reseals the nest entrance again until the young are ready to leave.
