Aceros plicatus, Papuan Hornbill, Blyth’s Hornbill, Julang Iria



The Papuan Hornbill (Rhyticeros plicatus) is also known as Blyth’s Hornbill. Its local name in Tok Pisin is kokomo. It is a large hornbill species inhabiting the forest canopy in the Wallacea and Melanesia.

Previously, this hornbill was placed in the genus Aceros. It has in the past been often lumped with the Plain-pouched Hornbill (R. subruficollis), and sometimes considered to include the Narcondam Hornbill (R. narcondami) and the Wreathed Hornbill (R. undulatus) as subspecies.

Up to 91 cm in length, the adult male has a mainly black plumage with a golden or orange-buff coloured head, white throat and a white tail. Its irides are reddish brown, surrounded by naked pale blue skin around the eye. The female is a smaller predominantly black bird with a white throat and tail. Both sexes have a very large, horn-coloured, bill and casque. Both sexes of young birds resemble the male. Adults have up to eight folds on the pale casque, depending on age, while young birds have none.
In flight the sound of its wings is loud and distinctive, a rushing noise that has been compared to the sound of steam escaping from a steam locomotive. As well as the noise produced by its wings, the Papuan Hornbill has a range of far-reaching, guttural grunting and laughing calls.
