Japanese Wood Mouse Doesn’t Like Acorns of Chinese Evergreen Oak Very Much

A field mouse [either Large Japanese field mouse (Apodemus speciosus, family Muridae) or Small Japanese field mouse (Apodemus argenteus, family Muridae)] nightly visiting the feeder site at the end of a fallen tree in the mountain forest. Although the feeder box was full of acorns of bamboo-leaf oak (aka Chinese evergreen oak and Chinese ring-cupped oak; Quercus myrsinifolia, family Fagaceae), the wood mouse seemed not to like them very much. The acorns of Quercus myrsinifolia are known to contain high doses of toxic and distasteful tannin. Captured with my old trailcam at night of late-November and early-December 2024 in Japan.
