Summary

These bat location estimates have been reported by Bogan and others (In press) and come in the form of a GIS shape file. Three species of nectar-feeding phyllostomid bats migrate north from Mexico into deserts of the United States (U.S.) each spring and summer to feed on blooms of columnar cacti and century plants (Agave spp). However, the habitat needs of these important desert pollinators are poorly understood. We followed the nighttime movements of two species of long-nosed bats (Leptonycteris yerbabuenae and L. nivalis) in an area of late-summer sympatry at the northern edges of their migratory ranges. We radiotracked bats in extreme southwestern New Mexico during 22 nights over two summers and acquired location estimates for [...]

Purpose

These radio telemetry data were collected to examine patterns of habitat use by long-nosed bats in and around the Animas Mountains of Hidalgo County, New Mexico, and to look for evidence of obvious differences in nightly movement patterns, activity timing, in general habitats used by L. nivalis and L. yerbabuenae in the study area, as well as among sex, age, or reproductive groups within each species. As detailed in Bogan and others (In press), these sympatric species of long-nosed bats in New Mexico might partition resources at finer spatial or temporal scales than we were able to discern with our coarse-resolution, qualitative analysis of these data. We did not obtain a sufficient number of precise and temporally consistent location estimates for quantitative analysis, primarily due to the difficulty of consistently detecting and tracking the same individuals from night to night, the inconsistent and haphazard locations of tracking stations necessitated by incomplete radio coverage, and weather interruptions of tracking efforts. Our sampling was additionally limited by the need to individually scan for multiple radio frequencies, resulting in inconsistent temporal sampling and missed opportunities to detect bats. These data are not appropriate for determining fine-scale habitat use, temporally consistent flight paths, or generally being interpreted for application to resource management beyond the scope of inference described in: Bogan, M.A., P.M. Cryan, C.D. Weise, and E.W. Valdez. In press. Landscape movement by two species of migratory nectar-feeding bats (Leptonycteris) in a northern area of seasonal sympatry.
