Mexican long-nose bat


A single cave, Cueva del Diablo, just outside Mexico City, one of the world’s most highly populated cities, is the only mating roost for the globally endangered Mexican long-nosed bat and is the only major roost known for the winter range of the species. The cave is under imminent threat of development and encroachment by speleological groups and amateur explorers.

Unfortunately, bats are susceptible to changes in their environment, and this type of routine disturbance in and around the cave reduces the suitability of the site for these bats. Humans entering the cave may also bring in pathogens to which these bats have no resistance.

If their only mating roost is made uninhabitable, it will be catastrophic for this nectar-feeding bat species. We need your help to stop the encroachment of this vital bat breeding site.  

At this very minute, the overwintering bats are at risk of cave-ins, disturbance by intruding humans, and destruction of the habitat they rely on. Every day we wait, these bats’ lives are at risk. Please make a gift today.
