Microtus canicaudus (gray-tailed vole)

Wikipedia Abstract

The gray-tailed vole (Microtus canicaudus) also known as the gray-tailed meadow vole or gray-tailed meadow mouse, is a rodent in the genus Microtus (small-eared "meadow voles") of the family Cricetidae. Voles are small mammals, and this species lies roughly in the middle of their size range. First collected in 1895, it is endemic to the Willamette Valley, Oregon, and Clark County, Washington, in the Pacific Northwest region of North America. Historically, they were found in the prairie areas of the Valley and, though many of these areas have been converted for agricultural purposes, these animals remain common. For reasons that remain unclear, vole population densities in any area may fluctuate widely from season to season and year to year. They are preyed upon by owls, hawks, and carnivor
