The mammal team has documented more than 25 species of mammals in the Sierra Cacachilas.
While this includes some large mammals like mule deer, bobcats, and coyotes, most of the mammals are small rodents and bats. Scientists have documented at least ten species of bats in the area. They have also discovered that several of the abandoned mine tunnels on the ranches are home to some of the East Cape's largest overwintering and maternity roosts of the endangered lesser long-nosed bat, Leptonycteris yerbabuenae.
Ecology of Desert bats
In April 2013, four scientists from institutions in the U.S.A. and Mexico initiated a study on demography and seasonal movements of the L. yerbabuenae. Detection equipment was installed in early 2015 at the entrance of an abandoned mine tunnel on the Rancho Cacachilas property as part of this ongoing long-term study.
