WEST GLACIER, Mont. [June 30, 2025] – Glacier National Park’s “Going Batty” field trip will be held on Thursday, July 17, 2025, in West Glacier from 8:00 p.m. to 11:30 p.m. The event is free and open to the public, but participation is limited and requires advance registration.

Glacier National Park’s biologist Lisa Bate and her staff, will lead participants on this late-evening field trip to a site with known bat activity. Wildlife staff will set up mist nets to capture and process bats and use acoustic detectors to detect the ultrasonic calls of bats flying overhead. These monitoring efforts are critical as bats face several threats, including a disease known as white-nose syndrome.

Participants will not be allowed to touch or handle bats and need to provide their own headlamps or flashlights, and face masks. Participants are encouraged to wear suitable clothing for the weather including sturdy footwear as well as a small backpack with food, water, extra clothing layers, and bear spray.

This field trip is limited to 35 participants. For more information and to sign-up, visit Volunteer Signup - Online volunteer signup sheets - Going Batty in Glacier National Park 🦇 signup sheet.

Bats make up twenty percent of all mammalian species found on Earth. They range in size from the tiny bumblebee bat, weighing less than a penny, to the flying fox bat, which can have a wingspan of up to six feet.

In Glacier, biologists have now confirmed the presence of ten bat species. The most recent addition, the Western Small-footed Bat, was confirmed during our 2022 Going Batty event. Three other species were added in recent years due to the park’s efforts to inventory and monitor bats.
