Late in the evening – three to eight hours after sunset – this bat forages for small to medium-sized flying insects over small water bodies in conifer forests. Daytime finds it roosting alone or occasionally in groups of three to six in tree foliage, cavities, under loose bark or sometimes in buildings. Silver-haired bats are relatively cold-tolerant and may be active at low air temperatures.
Silver-haired bats have one or two “pups” in June or July. They can fly at about three weeks and become sexually mature in their first summer. This species of bat occurs throughout the U.S. and most of southern Canada, though it winters in its summer range.
