Allen's big-eared bat (Idionycteris phyllotis) documented in colorado based on recordings of its distinctive echolocation call

Allen's big-eared bat (Idionycteris phyllotis) inhabits much of the southwestern USA, but has not been documented in Colorado. We recorded echolocation calls consistent with I. phyllotis near La Sal Creek, Montrose County, Colorado. Based on characteristics of echolocation calls and flight behavior, we conclude that the echolocation calls described here were emitted by I. phyllotis and that they represent the first documentation of this species in Colorado.

Colorado bat conservation plan

Eighteen of the 124 species of mammals inhabiting Colorado are bats. The unique life history characteristics of bats prevent many people from realizing that they comprise 15 percent of our native mammal fauna. Being fast fliers that are active at night, bats are mostly elusive to human senses except in the early evening hours when they can be seen foraging or when they are seen in their roosting habitat. In addition bats often roost in hard-to-reach, well-hidden places making human encounters with bats rare.
