Abstract
We determined the foraging range of Mexican free-tailed bats (Tadarida brasiliensis mexicana) that spend summer in Carlsbad Cavern, Carlsbad Caverns National Park, New Mexico. We captured bats at varying distances and directions from the cavern and attached a radiotransmitter to each. During daylight hours, we entered Carlsbad Cavern to determine if bats with radiotransmitters were present in the maternity roost. The distribution of localities where captured bats returned to Carlsbad Cavern indicated a nightly foraging range of at least 56 km from Carlsbad Cavern. Our data indicated that the colony eventually dispersed in every direction after leaving the cavern each evening and foraged in a space nearly 4,000 km3. This study was the first to document use of water sources on property of Carlsbad Caverns and Guadalupe Mountains national parks, the Lincoln National Forest, and other sites in southeastern New Mexico and western Texas by members of the colony of T. b. mexicana that reside in Carlsbad... Resumen Determinamos la extensión de forrajear de los murciélagos mexicanos de colas libres (Tadarida brasiliensis mexicana) que pasan los veranos en la Caverna de Carlsbad en el Parque Nacional de Carlsbad Caverns, Nuevo México. Apresamos murciélagos a distancias variables y a sentidos variables de la caverna y les pusimos emisores de radio. Durante las horas de luz, entramos en la Caverna de Carlsbad para determinar si los murciélagos con emisores de radio estaban presentes en su percha de maternidad. La distribución de las localidades donde los murciélagos apresados regresaron a la Caverna de Carlsbad sugirió una extensión de forrajear cada noche de por lo menos 56 km de la Caverna de Carlsbad. Nuestros datos dieron a entender que la colonia se dispersó eventualmente en todos sentidos después de salir de la caverna cada noche y luego forrajeó en un espacio de casi 4.000 km3. Esta investigación fue la primera que documentó el uso de fuentes de agua en la propiedad de los parques nacionales de Carlsbad C...Keywords
