Townsends big-eared bats - Dry Room 1970

Townsend big-eared bats roost in the Dry Room of Oregon Caves

All the bats found at the National Monument are insectivores that can consume as many as 500 insects an hour when feeding. Bats utilize Oregon Caves as a resting stop before returning outside to feed. They also use the caves to find mates, but their pups are usually born to the south.

Most bats at the Monument roost under the bark of old-growth trees in the summer. More bats come into the cave during very cold periods, perhaps because at that time their usual roosts under the bark on dead old-growth trees may not provide enough insulation.

A few individuals hibernate in the caves during the winter, so bats gates have been installed and the caves are closed in the winter to help protect these misunderstood furry friends.

The bats most commonly seen near the cave tour path are Townsend big-eared bats (especially in winter), Yuma bats, and long-eared myotis bats. Look for roosting bats - check out the Oregon Caves infrared "bat cam."

White-Nose Syndrome

White-nose syndrome, a fatal disease in bats, is threatening North American bat populations and could lead to the extinction of some species. Learn more about white-nose syndrome, what measures the Monument has put in place to prevent visitors from spreading it, and what you can do to help.

Did You Know?

Horse riders rode about 12 miles to Cave Camp located next to the entrance of Oregon Caves.

Up until 1922 the only way to get to Oregon Caves was on a 12 mile trail from the town of Williams, Oregon. Once at Oregon Caves visitors explored the cave and spent the night at a camp outside the entrance to the cave.
