The Knobbed Hornbill (Aceros cassidix) also known as Sulawesi Wrinkled Hornbill is a large black hornbill with a yellow bill, white tail feathers, pale blue skin around eye, blackish feet and bare dark blue throat. The male has rufous buff face and neck, orange-red eyes and a high reddish casque on top of bill. The female has black face and neck, yellow casque and brownish eyes.
As with other hornbills, the Knobbed Hornbill is believed to be a monogamous species. The diet consists mainly of fruits and figs. The female seals itself inside a tree hole for egg-laying. During this time, the male will provide foods for the female and the young.
The Knobbed Hornbill is the faunal symbol of South Sulawesi province.
