Praise Conservation of Free-Tailed Bat Colony


Target:  Ron Nirenberg, San Antonio District 8 City Councilman

Goal:  Praise Ron Nirenberg’s efforts to save the largest colony of free-tailed bats in the world

On October 31, 2014, the City of San Antonio obtained 1,521 acres of land adjacent to BCI’s Bracken Bat Cave, the largest colony of free-tailed bats in the world, to protect the bats that live there. Applaud the city’s move to conserve these bats’ environment in the face of human expansion and development.

The Bracken Cave is home to around 20 million Mexican free-tailed bats. Every night at 7:30, visitors see millions of bats fly out of the cave to hunt for bugs in nearby cornfields. The sight has been a source of awe and wonderment for many bat enthusiasts. The area, known as Crescent Hills, could not have been secured without the efforts of San Antonio District 8 City Councilman Ron Nirenberg, who led the effort, along with numerous conservation groups such as the Nature Conservancy and Bat Conservation International. Councilman Nirenberg called the efforts a “true conservation partnership.”

San Antonio has been experiencing major economic growth and an expanding population, and the need for animal conservation efforts is larger than ever. Protecting Crescent Hills is needed to ensure the bats will thrive and will not be threatened by economic development. A developer had begun to advertise his plan to build 3,500 homes in the area, which would have been a disaster because bats are attracted to the lights of homes. Securing this land for conservation was the right choice for both bats and humans.

Sign this petition to thank the city of San Antonio for carving out a place for these bats to live unthreatened by humans.


Dear Councilman Nirenberg,

I would like to applaud you for responding to the concerns of your constituents regarding bat conservation in Crescent Hills. Thanks to your actions and partnership with bat conservation groups, you were able to successfully secure land to protect the bats, in addition to an important water supply source and local songbirds that inhabited the area.

If the developer who owned the land had used it to build 3,500 homes as he had originally planned, the bats and homeowners would have had to cohabit the area–a terrible situation for bother the bats and the people. You did the right thing by working so hard to buy the land from the developer and save this unique species.

The Mexican free-tailed bat is a precious treasure to Crescent Hills and it is vital that we continue to work to conserve this species. Thank you for your valuable efforts to secure the land and protect these bats.
