The Tama area is an area where rapid urbanization is progressing. The possibility of wild life decrease because of urbanization has been noted before. In the Tama area, although the monitoring of avifauna had been conducted, the avifauna monitoring survey has not been performed recently. Therefore, the current avifauna present in the Tama area is unclear. We conducted a census survey of birds in the Field Museum Tama Kyuryo of Tokyo University of Agriculture and Technology, located in the center of the Tama area, during 2015 and 2016, and identified the current avifauna. We recorded 24 bird species, and the most common species were Japanese tit (Parus minor), Japanese white-eye (Zosterops japonicus), Japanese bush warbler (Horornis diphone) and Long-tailed tit (Aegithalos caudatus). Almost all species were similar to those recorded in the previous study. This result suggests that the Tama area maintained the environmental condition of the isolated forest as a bird habitat. In addition, Eurasian woodcock (Scolopax rusticola), which was newly recorded in this study, was designated as an endangered species in the Tokyo Metropolitan Red Data Book. Information on the habitat of Eurasian woodcock was insufficient because observation is difficult. This result suggests that endangered species could even inhabit urban forests that have the necessary environmental conditions. It is important to monitor avifauna regularly to manage the environmental conditions in urban forests.
