Limited information exists on the choice of day roosts by red bats (Lasiurus borealis) in mature deciduous forests. We radiotracked 10 adult female and 4 adult male red bats as they used 44 day roosts in mixed mesophytic forests in eastern Kentucky during May through August 1996-97. On average (x̄ ± SE), bats roosted 16.5 ± 0.3 m above ground in the outer foliage of the canopy of 13 different species of hardwood trees; no conifer or snag was used as a day roost. Roost trees were dominant and codominant trees averaging 40.8 ± 1.9 cm dbh. Most roost trees (77.3%) were on ridge tops of upland forests. Each bat used an average of 3.1 roost trees and switched roost trees every 2.3 days in an area <40 m-2. Day roosts were 277 ± 30 m from forest edge, with no roost located <50 m from any edge. These data indicate that choice of day roosts by red bats inhabiting tracts of mature contiguous forest differs from those in fragmented habitats.
