The hoary bat (Lasiurus cinereus) inhabits New York, the northern part of its range, from early summer until the early fall. These migratory bats spend the winter in the southern part of their range: southern USA and Central America. This tree bat has been documented in several habitat types, from eastern hemlock stands to bridge beams; however, its solitary nature, use of high canopy levels for day-roosting, and fast flight make individuals difficult to locate for detailed habitat studies. This study uses sonar detection and GIS technology to identify hoary bats in flight and determine habitat characteristics of the areas used by the species. After two field seasons, preliminary statistical analyses have been conducted to determine if there are any trends thus far. Ultimately, these data can be used to quantify habitat preferences of this bat in New York and develop a habitat model for managing this poorly known species.
