The survey period for the study was from July 23, 2019, to September 27, 2021. Thirty survey points were set and 152 bats of eight species were captured. Plecotus sacrimontis and Murina hilgendorfi were the first bats discovered in this area, and 10 species of bats have been reported in Abashiri City. Barbastella darjelingensis, Myotis ikonnikovi, and Murina ussuriensis accounted for 89.3% of the captured bats, and B. darjelingensis was captured the most. The presence of coniferous trees, which are used for roosting, and broadleaf trees that host moths, which are their staple food, were thought to be related to the habitat of B. darjelingensis. Swelling of the abdomen and nursing marks during pregnancy were confirmed in five species of bats, suggesting that childbirth and child-rearing were being performed. A survey near the outdoor lights at the crest of the dam confirmed its use by bats. Six pregnant and child-rearing animals of the B. darjelingensis were captured at three survey points in the center of “Okhotsk Forest”. Since they were captured immediately after the start of the survey, it is probable that there were birth and child-rearing colonies of B. darjelingensis near the survey points., E, 1, P, 論文, Article}, pages = {31--39}, title = {北海道網走市越歳「オホーツクの森」 におけるコウモリ相}, volume = {68}, year = {2023}, yomi = {サカウエ, ダイゴ and コンドウ, ノリヒサ and ワタナベ, メグミ and ソウマ, コウサク and オオクボ, ミチコ} }
