Bristlehead

The Bornean bristlehead (Pityriasis gymnocephala) is a distinctive and unique bird found exclusively in the rainforests of Borneo, identifiable by its red and black plumage, bald yellow crown with bristle-like projections, and a heavy hooked bill. This medium-sized bird, approximately 25 cm in length, exhibits sexual dimorphism with females having additional red spots on their flanks. They live in a variety of forest habitats including peat swamps, dipterocarp, and mangroves, up to elevations of 1200 meters. Their taxonomic classification has sparked debates, but recent insights suggest they might belong to the Tephrodornithidae family. Bristleheads are sociable, moving in small flocks in the forest canopy, often joining mixed-species groups while foraging. Their diet consists mainly of small plants, fruits, and vegetables. Despite uncertainties about their breeding habits, communal nesting is suggested by observations of cooperative feeding. The species is under threat due to habitat loss from logging and forest burning and is thus classified as vulnerable. Their varied calls include nasally whines, chatters, and honks, which can be heard as they navigate the forest.
