FAQ

1. Where do bats in Montana go in the winter?

Some of the state’s bats, like the Silver-haired Bat and the Hoary Bat, are migratory and will fly south for the winter. However, others, like the Townsend’s Big-eared Bat and the Big Brown Bat, will try to locate a cave within the state that is suitable for them to hibernate.

2. Are there any species of bats in Montana that are endangered?

While the Northern Long-eared Bat is federally threatened, the USFWS is pushing to list it as endangered as the population has declined in the state. This drastic decline is especially pronounced in eastern Montana, where bats have begun to show symptoms of White-nose Syndrome. This disease afflicts bats living in caves and can lead to rabies.
