We classified each prey into size classes based on mass with <1 kg as "small" (S), 1-6 kg as "medium" (M), and >6 kg considered "large" (L) Taxa Common name Size Mammalia Artiodactyla Odocoileus virginianus White-tailed deer L Soricomorpha Sorex cinereus
Masked shrew S Blarina brevicauda Short-tailed shrew S Lagomorpha Sylvilagus spp.
Similar patterns were determined in several clades of other soricids preferring intermediate elevations as in Sorex monticolus species complex inhabiting the Rocky Mountains and adjacent regions in western North America (Demboski & Cook 2001, Himes & Kenagy 2010) or Sorex cinereus
in the Appalachians in eastern North America (Sipe & Browne 2004).
Swengel and Swengel (1992) also reported shrews (both Sorex cinereus
and short-tailed shrew Blarina brevicauda) as prey of Saw-whet Owl.
Measurements for Sorex cinereus
(n = 1; from Recent specimen) and Sorex taylori (n = 1; from cast of University of Michigan Museum of Paleontology no.
has a distribution spanning most of the Nearctic and exhibits distinct genetic population structure coincident with geography (Hope and others 2012) reflecting fragmentation in the contiguous United States during the Wisconsinan.
The only previous record of fossil Sorex from Michigan was a late holocene record of Sorex cinereus
from Mackinac County (Holman et al.

Logan and Black (1979) noted that the only correlation between the two trenches is based on presence of Cryptotis parva (least shrew) and Sorex cinereus
(masked shrew) in the 30-40 cm level of Trench 1 and the 10-20 cm level of Trench II.
