Range DescriptionPtilinopus marchei is endemic to the island of Luzon in the Philippines, where it occurs chiefly in the northern provinces (Collar et al. 1999). It is known from at least 17 sites, with records from at least 11 since 1980. It was considered to be fairly common in the Abra highlands and on Mts Sicapo-o and Data during the 1940s and 1950s. However, it was uncommon or rare in the Sierra Madre mountains, except at Los Dos Cuernos, during surveys in the early 1990s. There are recent records from Balbalsang, Kalinga province (where apparently fairly common), Mt Data (where rare; possibly only two pairs), Mt Polis (presumably breeds) and Mt Amuyao (where heavily hunted) (D. Allen in litt. 2012). Familiarity with its call might reveal a greater abundance.
