Western yellow bat records in Texas sit in the Trans-Pecos, with Big Bend, the Guadalupe Mountains, and the Davis Mountains carrying the record set. This bat roosts in dead palm fronds, Spanish moss, and dense tree foliage along desert washes and river corridors, so its presence tracks that kind of streamside cover through otherwise dry country.
Records are thin, just 26 total, and the most recent listed sighting dates to February 2021, more than five years old even as bat monitoring continues elsewhere in the state. May and July each hold 5 of the 26 records, too small a sample to call a real seasonal peak.
NatureServe ranks it S1, Critically Imperiled, in Texas, a much sharper concern than its G4, Apparently Secure, global status, marking it as one of the state’s rarest bats on paper.
