The hoary bat has a wingspan of nearly 16 inches. It has dark fur tipped with white, a dark mask on its face, a yellow-orange throat and round ears edged in black.

This bat roosts in branches of trees and likes to feed around outdoor lights. Hoary bats migrate south in winter, returning to Oregon in the spring. This bat usually bears twins.

Hoary bats are found at scattered localities over most of the region west of the Cascade Range and in montane regions east of the Cascade Range. They are an Oregon Conservation Strategy Species in all ecoregions except the Nearshore.
