FIRST RECORD OF THE EASTERN PIPISTRELLE (PIPISTRELLUS SUBFLAVUS) FROM SOUTHERN NEW MEXICO

摘要

The range of the eastern pipistrelle (Pipistrellus subflavus) recently has expanded westward in the United States. New records of this species have been reported along the entire western boundary of its range from South Dakota to Texas. In August 2004, we captured an adult, male eastern pipistrelle at Carlsbad Caverns National Park in southeastern New Mexico. Our record represents the second capture of this species in New Mexico and the first in the southern part of the state. Because no eastern pipistrelle was captured at this site during previous surveys (1973 to 2003), this record represents the continued westward expansion of the distribution of this species in the United States.
