| 本研究はニホンモモンガPteromys momongaの生息に必須な資源であると考えられる樹洞について，スギCryptomeria japonicaやヒノキChamaecyparis obtusaの利用実態を明らかにすることを目的とした．本種の営巣確認を2005年3月から2010年4月の間に神奈川県丹沢山地の針広混交林で行った．その結果，ニホンモモンガの営巣は広葉樹の樹洞木20本のうち1本，針葉樹の樹洞木23本（スギ21本，ヒノキ2本）のうち8本で確認され，営巣のために針葉樹の樹洞木を多く利用していることが明らかになった．また針葉樹の営巣木はすべてスギであった．スギ・ヒノキにおける営巣木の樹高，胸高直径および樹洞の高さはそれぞれ25.6±3.7（平均±SD）m，50.3±11.2 cmおよび6.2±0.6 mで，営巣が確認されなかった樹洞木との間に有意差は認められなかった． |

| Describing the interactions among cavity breeders is key to understanding their breeding ecology. In this study the temporal difference in cavity use between the great tit, Parus major (Linnaeus, 1758) and the small Japanese field mice, Apodemus argenteus (Temminck, 1845) is investigated, as a first step for clarifying the interaction between bird and mammal cavity breeders. Forty-seven nest boxes were installed on tree trunks in two urban forests of Hokkaido Island, Japan, and the breeding nests of tits and mice were found in 34 and 11 boxes, respectively. The tits used the nest boxes throughout the breeding season, from May to July. In contrast, mice breeding nests were found in the last half of the breeding season, from July to October.
