The Big Free-tailed Bat (Nyctinomops macrotis) is a large (12-16 cm [5-6 in]) bat that can be found in the rocky terrains of Arizona, California, Colorado, Nevada, New Mexico, and Texas. It has a glossy or greasy coat. It catches and eats moths, crickets, and flying ants while they are in flight. The Big Free-tailed Bat will experience a high degree of climate exposure and has a moderately high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Less Vulnerable under the Representative Concentration Pathway (RCP) 4.5 Scenario and Moderately Vulnerable under the RCP 8.5 Scenario. The Big Free-tailed Bat’s climate change vulnerability is impacted by factors related to distribution, movement, life history, and abiotic niche, which influence its ability to shift in space, persist in place, and respond to climate change impacts.
