This study is conducted to investigate number of species in various habitat size in the area of urban biotope in Seoul from October to November in 2001 and from May to June in 2002. It is established that habitat size does not significantly affect the number of species in urban biotope. Thirty-two bird species were observed in 54 sites. Thirteen species of birds used sites of up to 1㏊, 29 species from 1 to 10 ㏊, and 8 species in the sites larger than 10㏊. We find that most of species appeared in size (1-10㏊), rather than in size (<1㏊, >10㏊). The cumulative number of species for a given cumulative area was consistently higher when small sites were added first. We think that this habitat size is the actual area to promote number of species within the urban area. Also, there was significant increase of number of species at biotope with water source and multiple vegetation structure. Therefore, if water resources and multiple vegetation structure is maintained, even small area can be helpful to the bird species promotion.
