Conserving and restoring at risk species and ecosystems on the BC South Coast

Trowbridge's Shrew

Sorex trowbridgii

This is perhaps the least studied shrew in BC where it is considere rare. As with many other at risk shrew species Trowbridge's Shrew is restricted to the extreme southwest of the province where it is also at the northern end of its North American range.

COSEWIC: Endangered BC List: Red

Trowbridge’s Shrew is uniformly dark grey, slightly browner in summer than in winter, with distinctly white feet. Vibrissae (whiskers) are numerous and the skull and rostrum (snout) are shorter, giving this species a rounder face and head than other shrews. Juveniles have hairy tales that become naked like a rat’s as they mature. In shrews dentition patterns, shape and number are a key identification tool. The third unicuspid is smaller than fourth and the teeth are pigmented a dark reddish-brown. Only one picture of this species is know to have been taken (provided).
