Papuan Hornbill

Rhyticeros plicatus

The Papuan Hornbill is one of the largest and most striking birds of the New Guinea region, a frugivorous giant of lowland and hill forests that ranges across Papua New Guinea, the Solomon Islands, and the Maluku Islands. Males are unmistakable: a creamy white head and neck contrast sharply with jet-black body plumage, while the large corrugated casque atop the bill turns deep rufous-orange in adult males. Females are entirely black with bare blue facial skin, making the sexes look like different species. Like other hornbills, they are cavity nesters — the female seals herself inside a hollow tree using mud, droppings, and food remains, leaving only a narrow slit through which the male passes fruit for weeks at a time.

During the breeding season, the female Papuan Hornbill seals herself inside a tree hollow, remaining confined for up to three months while the male delivers all her food through a narrow slit.
