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
