| Identification Comments: | |
| Subspecies Comments: | |
| Food Habits: | Food items include a variety of insects but moths, dragonflies, and beetles feature prominently. Foraging is generally high altitude and occurs over the tree canopy. In the open, rapid descending arcs are exhibited. Also, hoary bats will follow watercourses for foraging and drinking. They are capable of foraging over long distances, up to 40 km (25 miles) from its roost (Altenbach et. al. 2002). |

| Reproduction Comments: | |
| Migration Mobility: | |
| Habitat Comments: | Hoary bats are a tree-roosting species, found primarily in forested upland habitats such as pinyon-juniper and conifers, as well as in gallery forest riparian zones (e.g., in cottonwoods along the Colorado river drainage). Current Nevada records indicate this species is distributed between 570-2,520,m. Hoary bats day roost in trees 3-12 m above ground and are protected by good leaf cover, but open below to facilitate flying in/out of the roost. They are basically solitary, except for mother-young association; however, during migration, groups of up to hundreds of individuals may form. Some mother-young groups will often change roosts whereas others do not; movements generally are less than 100 m from the previous roost. It is generally assumed that this species migrates from the state during winter, but wintering habits are not confirmed. Elsewhere hibernating individuals have been found on tree trunks, in a tree cavity, in a squirrel's nest, and in a clump of Spanish moss. |
