NORTH AMERICAN RANGE & HABITAT:
Silver-haired bats forage over woodland ponds and streams, and usually reside in forested habitats. Males roost alone; females apparently form small nursery colonies in three hollows and woodpecker holes. Day roosting sites include under loose tree bark, bird nests and in woodpecker holes. They may also appear in any kind of building, but favor open sheds or garages versus closed attics.
Silver-haired bats undertake seasonal migrations, often in the company of red bats and small birds. They frequently collide with radio towers and high-rise building during their fall migration, . Silver-haired bats hibernate is trees, buildings and rock crevices. Seasonal, geographic segregation of the sexes is likely in this species. In summer studies have found males in the southwest exclusively, with females in northeast.
Little is actually known about this bat and its behavior, including breeding behavior and reproduction. Because of its forest roosting habit, the silver-haired bat is difficult to see and is rarely encountered by humans. They are one of the slowest flying bats in North America.
