Seasonal change of a bird community and its habitat utilization pattern in campus of the Faculty of Horticulture of Chiba Univiversity, Matsudo, Chiba prefecture, were investigated by monthly route census from April 2001 to March 2002. Forty-three species of birds were observed during the period with 2 other species which had been confirmed a year before. These birds were classified based on the habitat preferences: forest, grassland, intermediate (living between forest and glassland) and water birds, with the stages of life cycle in mid-south of Japan: resident breeder (RB), migrant breeder (MB), passive visitor (PV) and winter visitor (WV). Bird species observed in the forest is most abundant (24 species) in the campus, reflecting the large area of forest. Seven water birds and Cisticola juncidis were considered as accidental visitors on campus, because there is little water or large grassland. Total 37 terrestrial birds species are the inhabitants or users of this place. Thirteen RB species with one MB species and five forest habitat species with six intermediate and three grassland habitat species were observed throughout the breeding season from early spring to autumn, while the other birds appeared infrequently. During winter, however, 32 species of RB, WV and PV were observed mainly at semi-natural forest and at experimental fields on campus including many birds of forest and woodland habitats, e. g. goshawk Accipiter gentilis and dusky thrush Turdus naumanni. More than 700f winter birds were observed more than three times during winter and they seemed to pass the winter in the campus. At mid-spring and early autumn, some migrant birds also visited the campus for a short term. Therefore, most of forest birds and half of intermediate birds utilized the campus mainly for overwintering or rest during migrations, while only a few species of birds actually breed on campus.
