Comparative study on the foraging habits of two species of soricine shrews

We compared the daily activities and digging abilities of Sorex unguiculatus Dobson, 1890 and S. caecutiens saevus Thomas, 1907 in the laboratory. Activities of the two species increased at night, but S. caecutiens was more nocturnal than S. unguiculatus. The level of feeding activity was almost constant throughout the day, and its proportion to the total activity was higher in smaller S. caecutiens than in larger S. unguiculatus.
