Knobbed Hornbill

The knobbed hornbill (Rhyticeros cassidix), also known as Sulawesi wrinkled hornbill, is a colourful hornbill native to Indonesia. This species is sometimes placed in the genus Aceros. The species is the faunal symbol of South Sulawesi province. The species is a large black hornbill with a yellow bill, white tail feathers, pale blue skin around eye, blackish feet and bare dark blue throat. Like other hornbills, the species is sexually dimorphic. (Wikipedia, general species account).

An Indonesian endemic, the knobbed hornbill is found in Sulawesi, Buton, Lembeh, Togian and Muna Island. Habitats used include evergreen forest at an elevation of up to 1,800 m and also makes use of secondary forest, woodland and plantations for foraging. The female seals itself inside a tree hole for egg-laying using its own feces. Knobbed hornbills are important seed dispersers in their habitat and influence the initial fate of seeds of several tropical forest tree species. (Wikipedia, general species account).
