Baird’s Shrew

Taxonomy. Sorex bairdi Merriam, 1895 View in CoL ,
USA, “ Astoria [Clatsop Co.], Oregon,” USA.
Sorex bairdi is in the S. sonomae group and subgenus Otisorex. Whether S. bairdishould be included as a subspecies or synonym of S. pacificus or retained as a separate species is up for debate because genetic data show that the two are not very distinct based on mtDNA. Nevertheless, they are retained as separate species here because of their dis-
tinctive morphologies. Two subspecies recognized.
