  • Pityriasis gymnocephala, a passerine and the only member of the family Pityriaseidae, endemic to Borneo. A large black bird with a read and yellow head (females have some red in the wings), a massive black hooked bill, and a short tail. Short, colored projections like bare feather shafts appear on the crown of the head, lending it the name "bristlehead."
