Help protect the only known mating roost for the endangered Mexican long-nosed bat

Over 21 million people live in the Mexico City metro area, and in addition to their human neighbors, they share geography with the endangered Mexican long-nosed bat (Leptonycteris nivalis). Cueva del Diablo is located just outside the city and this cave is the only known mating roost for the species. Bat Conservation International is working with local partners to help permanently protect this vital site through our end of year campaign.

Development is occurring that imperils this cave and its bat residents. A home was built just five feet from the cave entrance where the bats enter and leave, and other structures are being built on unstable ground directly above the cave. The ground underneath one home buckled and collapsed, sending the structure into the cave below. No one was injured, thankfully, and the bats weren’t roosting, but it’s easy to see why it is so important to keep development away from Cueva del Diablo. Spelunkers are also venturing into the cave to explore, disturbing the bats and disrupting the environment, potentially allowing disease to be introduced into the cave. Since this is the only known mating roost, it is vital to protect it in order to protect the species.

“This is the only roost (we know of) where both sexes coincide in winter,” says Bat Conservation International researcher Dr. Ana Ibarra. “So, we have a big proportion of the species population in a single spot, in a specific time span. Something happens to this cave in winter, when the Mexican long-nosed bat colony is present, and the species takes a major hit.”Building on the work of esteemed bat conservationist Dr. Rodrigo Medellin, Bat Conservation International is working with Dr. Medellin and other in-country partners, and community members to protect this site and the bats that rely upon it.
