Recent attentions have been paid to the reduction in the species diversity of bird fauna caused by the shrinkages and/or fragmentations of vegetation due to urban developments. Here, we investigated the bird fauna in an urban woodlot (Mie University campus) and a suburban stand (RedHill Hiisa's Forest owned by Akatsuka Garden Co., Ltd) in Tsu, Mie prefecture, Japan for ca. 32 months, and discussed the possible factors responsible for affecting the diversity of the bird fauna. We performed a line census about once a month in both sites. We identified in the woodlot 23 families, 27 genera and 31 species, including many city species, that is, those species that prefer to open sites and/or possess a wide ranges of habitats preferences. In the suburban stand, we identified the 22 families, 31 genera and 35 species, including not only city species, but also forest-specific species such as Zosterops japanicus and Aegihalos caudatus were also observed. The number of species found per census and Shannon-Weaver index (H') for the bird fauna were higher in the suburban stand than in the woodlot. Furthermore, the suburban stand exhibited a pronounced seasonal variation in the number of bird species than the woodlot; the species number was markedly highest in winter. These results suggest that the suburban stand provided the habitats for various bird species.
