This bat, found in older forests, has a wingspan of about 10 inches. Its fur is glossy black, tipped with white. It forages over ponds, streams, meadows and roads, often flying very low and roosting behind loose tree bark.

Maternity roosts of the silver-haired bat are found in trees. This bat usually bears twins.

The silver-haired bat occurs statewide in Oregon except for most of the Columbia Basin and is an Oregon Conservation Strategy Species in all ecoregions except the Nearshore ecoregion.

 It is primarily associated with coniferous forests, including the juniper woodlands in the southeastern portion of the state. It sometimes occurs in mixed deciduous-coniferous forest, and during migrations in May and September it occurs in rangelands where it forages along small streams.
