Inside the Cave
At least eight of the fifteen bat species found in Oregon occur within the boundaries of Oregon Caves National Monument. Most bats seen by the main trail are Townsend big-eared bats, Yuma bats, long-eared myotis bats, silvered-haired bat, big brown bat, Western small-footed bat, California myotis, little brown myotis, and fringed myotis.
Outside the Cave
Squirrels, chipmunks, and fox are quite common. Black bears, cougars, and Mountain beaver are a bit more secretive.
Did You Know?
Dragonflies and damselflies are ancient creatures that have lived on Earth far longer than mammals. They have sophisticated eyes, over twenty to thirty thousand per head. Dragonflies are fast fliers; the blue-eyed darner can fly 48 feet per second while chasing prey. Most can fly far, even able to survive crossing a sea or ocean, if they have to.
