In the heart of Texas, an hour’s drive northwest of Fredericksburg, the Eckert James River Bat Cave Preserve is the summer roosting place for four to six million Mexican free-tailed bats (Tadarida brasiliensis).

In 1907, Richard Phillip Eckert and his wife Virginia Eckert Garrett purchased the limestone cave and ranch site and mined the bat guano to sell to local farmers for crop fertilizer. The cave and ranch were later donated to The Nature Conservancy of Texas with one condition that the site remain open to the public.
