That year Kenneth C. Parkes studied a series of 45 specimens and recognised five subspecies, two of which were new.

[3] It batters its prey, which consists of large insects, spiders[3] and small vertebrates.

[1] This species is endemic to the Philippines, ranging from Samar and Tablas south to Mindanao, Basilan and the Sulu Archipelago.

Forest clearance and illegal logging are causing habitat loss and a fast population decline, so the IUCN has assessed it as a vulnerable species.
