§1

Description

A medium bird of the forests of Panay and Negros. It has a gray crown, back and rump. Wings are primarily black with a white wingpart, tail is also black with white tips and vent. This species exhibits sexual dimorphism in which the male is much darker than pale females. Its call is described as a sharp downward chirp often repeated 10-20 times. This species is monotypic and has no subspecies.

§2

Range & habitat

Its natural habitats at tropical moist lowland primary forest and secondary forest up to 1,300 meters above sea level. While they can tolerate secondary forest, they have the highest population densities and health in primary (old-growth) forest. As of 2025, This species is assessed as Near-threatened species by the International Union for Conservation of Nature. The population is believed to be declining with populations estimated between 2,500 and 9,999 mature individuals. Prior to 2025, this species was listed Vulnerable species. Its main threat is habitat destruction through both legal and Illegal logging, conversion into farmlands through Slash-and-burn, charcoal burning, and mining. Its preference for low altitudes suggests that it must have suffered population losses with the loss of lowland forest in the Philippines. Habitat loss on both Negros and Panay has been extensive. By 2007, Negros and Panay had a 3% and 6% remaining forest cover with most of this being higher elevation forest where this bird does not thrive in with these figures are still declining. It occurs in a few protected areas on Northern Negros Natural Park, Mount Kanlaon National Park and Northwest Panay Peninsula Natural Park. …
