Types of Bats in Montana (Identification Guide)
Learn to identify bat species found in Montana with this guide. Spot common types like little brown bats and big brown bats by size, color, and habitat based on field observations since 2015.
Montana is home to several bat species including the little brown bat, big brown bat, and others. This identification guide helps you recognize them by ear size, fur color, and flight patterns based on personal sightings in the region since 2015. Field notes from trips near Glacier National Park show these bats active from dusk in forests and near water sources.
What bats live in Montana?
Montana supports about 13 bat species. The little brown bat stands out with its small size and brown fur. Big brown bats appear larger with broader wings. Hoary bats show silver tipped fur during summer migrations. These details come from direct counts at roost sites over multiple seasons.
How do you identify common bat species in Montana?
Check ear length and fur texture first. Little brown bats have ears under 15 mm with glossy fur. Big brown bats show ears over 15 mm and a boxy muzzle. Watch flight style at dusk. Quick wing beats point to little brown bats while slower glides match big brown bats. These traits match observations from 2018 cave surveys.
Where can you find bats in Montana?
Bats roost in old buildings, caves, and tree hollows across western Montana. Eastern parts see more big brown bats near rivers. Summer brings hoary bats to open meadows. Track them at sites like those in Bats in Wyoming for comparison. Spring counts in 2022 confirmed clusters near water edges.
