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.

Taxonomy
While the taxonomic history of the Sulawesi Hornbill has been uneventful, the number of species in the Philippine Archipelago has been greatly debated. Traditionally, only a single Philippine species was recognized, the Tarictic Hornbill (P. panini). Following a review, it was recommended that it should be split into four allopatric species, the Visayan (P. panini), Luzon (P. manillae), Mindanao (P. affinis), and Mindoro (P. mindorensis). Today most authorities accept these splits, although some, for reasons that are unclear, also have recommended splitting the Samar (P. samarensis) from the Mindanao.
