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

NEW REPORT ON THE DIET OF THE BLUE WHISTLING-THRUSH (Myophoneus caeruleus) IN KAKEK BODO WATERFALL, STATE-OWNED FOREST IN PRIGEN, PASURUAN (EAST JAVA)

The Blue Whistling-Thrush (Myophoneus caeruleus) is a member of Turdidae family which is comprised of six races distributed from Turkestan up to India and China, Southeast Asia, Malay Peninsula, Sumatera, and Java. This bird can be found around large rivers or between ridges in the forests. On 13 December 2012, we conducted an observation around the Kakek Bodo Waterfall’s camping ground and tourism site, Prigen, Pasuruan. The observation resulted in the sightings of five endemic bird species (the Olive-backed Tailorbird, Crescent-chested Babbler, Yellow-throated Hanging-parrot, Javan Banded-pitta, Lesser Forktail), and a bird with minimal record bird in Java, the Thick-billed Flowerpecker. Another result of the observation is a new data on the diet of the Blue Whistling-thrush. This species is known to prey on snails, beetles, maggots, worms, and water bugs; however, that one bird we observed was preying on a snake (from the genus Dendrelaphis). This species had also been reported to scavenge for leftovers thrown away by food vendors in the tourism site, so that its behavior has gradually changed.Keywords: Blue Whistling-thrush, Dendrelaphis snake, diet, Kakek Bodo waterfall
