Penelopides

Penelopides is the genus of relatively small, primarily frugivorous hornbills found in forests of the Philippines and the Indonesian island of Sulawesi. Their common name, tarictic hornbills, is an onomatopoetic reference to the main call of several of them. They have a ridged plate-like structure on the base of their mandible. All are sexually dimorphic, with males of all except the Sulawesi Hornbill being whitish-buff and black, while females of all except the Mindoro Hornbill are primarily black.
