The hoary bat is the most widely distributed bat in the United States. Hoary means "frosted", and refers to the white tips of the body hairs. This bat has a distinctive yellowish-brown collar under its chin. The hoary bat is migratory and may travel from Canada to the southern United States. Most like to overwinter in coastal areas. They are a solitary bat and roost among dense foliage in evergreen forests and wooded areas. The hoary bat hunts over open areas or lakes, and its main source of food is moths.
The hoary bat has a set of twins each year in the late spring or early summer and they spend about one month with their mother before they are on their own. The lifespan of a hoary bat is six to seven years.
