Abstract

The latest information about the distribution of a less-recorded Java-dwelling bird species found in Tahura Raden Soerjo (East Java) is noteworthy additional information in the field of ornithology. Observations were conducted in the Cangar tourism site, along the main road linking Pacet and Batu, as well as in the northern area of Tahura Raden Soerjo, which includes the hiking trails of the Welirang-Arjuno mountains. The birds with minimum records are the Hill Myna (Gracula religiosa), Thick-billed Flowerpecker (Dicaeum agile), Yellow-vented Flowerpecker (Dicaeum chryssorheum), Sunda Thrush (Zoothera andromedae), Narcissus Flycatcher (Ficedula narcissina), Brown Wood-owl (Strix leptogrammica), Oriental Bay-owl (Phodilus badius), and Rhinoceros Hornbill (Buceros rhinoceros). Several findings are supported with detailed documentations and direct observation data that can be accounted for. This information denotes that Tahura Raden Soerjo is a potential hotspot to be preserved for the sake of the rare bird species and the other biodiversity.
