Range DescriptionApalharpactes reinwardtii is known from seven forested mountains in West Java, Indonesia: Gunung Halimun, Gunung Salak, Gunung Gede-Pangrango, Gunung Patuha-Tilu, Gunung Wayang, Gunung Papandayan and Ciwidey. There are only recent records from four of these (Halimun, Salak, Gede-Pangrango and Ciwidey). The historical range totals 11,600 km2. Although it has been stated to occur at 800-2,600 m, little forest remains below 1,000 m away from Halimun, and the species appears to be rarer at higher elevations. The only site where the species appears to be common now is Gunung Halimun, but only at lower elevations. The population size of this species may be as low as a few hundred pairs (Collar and van Balen 2002).
