Chestnut-bellied Hill-Partridge (Arborophila javanica) is an endemic species of Java, and also one of four endemic partridge species in the Greater Sunda islands. This species is constituted by three subspecies which differ in the color pattern of their head. The first reported sighting of Chestnut-bellied Hill-Partridge (Arborophila javanica lawuana) in Cangar is by Nijman in 2003, and for these past ten years the observation data has been inadequately obtained by local birdwatchers although its call is remarkable ; the call might be frequently heard by birdwatchers but got missed. Several information about this bird has been collected, including its sound recording that we used during observations. Observations were conducted around Cangar tourism object, particularly along the main road linking Pacet (Mojokerto) and Batu (Malang). The observations resulted in the data on its behavior and the best observation spot, that is in Lemahbang.Keywords: Chestnut-bellied Hill-Partridge, endemic bird, observation spot, Tahura Raden Soerjo
