Silver-haired bats get their names from their dark brown to black fur with silvery tips. Their tail membranes also have dark fur on the back side. Ears are short and rounded.
They range in body weight from 8-11 grams with wingspans of 11-13 inches (27-32 cm).
Silver-haired bats can be found in the southern parts of Alaska, Canada, throughout most of the United States and into Mexico.
Ecology and Behavior
These bats are solitary and prefer to roost under exfoliating bark on trees. They will sometimes use open man-made structures as well.
They forage for food over water sources and have been seen eating moths, flies, midges, beetles, and termites.
