Phtotograph: Ron Groves

The Mexican free-tailed bat became the official flying mammal of the State of Texas when Governor George W. Bush signed Senate Concurrent Resolution No. 95 on May 25, 1995.

S.C.R. No 95


WHEREAS, The largest concentration of Mexican free tailed bats in the world exists at Bracken Cave in Comal County; and

WHEREAS, This particular cave in Texas is known as a summertime nursery cave for a large population of migratory Mexican free tailed bats whose numbers may exceed 20 million; and

WHEREAS, Mother bats give birth to a single pup in June or early July; at night each mother travels long distances to find enough food, consuming approximately her own body weight in insects; and

WHEREAS, At Bracken Cave, the 20 million bats there devour 250 tons of insects; throughout the summer the number of insects including mosquitos and crop pests disposed of is immeasurable; all of this is accomplished without the use of pesticides; and

WHEREAS, Increasingly, the importance of bats in a healthy ecosystem is being appreciated and protected; this is especially true in Texas; and

WHEREAS, Bat Conservation International is an organization with headquarters in Austin that is dedicated to educating the public about bats and conservation of the species; its members are interested in having the Mexican free tailed bat recognized as the "Official Flying Mammal" of the State of Texas; now, therefore, be it

RESOLVED, That the 74th Legislature of the State of Texas hereby declare the Mexican free tailed bat the "Official Flying Mammal" of the State of Texas; and, be it further

RESOLVED, That a copy of this resolution be prepared for Bat Conservation International as an expression of the high regard of the Legislature of the State of Texas.

Often referred to as the Brazilian free-tailed bat, Mexican free-tailed bat is an alternate common name for Tadarida brasiliensis.

Bats of Texas

Bats of Texas, by Loren K. Ammerman, Christine L. Hice, and David J. Schmidly. Illustrations by Carson Brown. Photographs by J. Scott Altenbach. 288 pages. Publisher: TAMU Press (November 23, 2011) Texas is home to all four families of bats that occur in the United States, including thirty-three species of these important yet increasingly threatened mammals. Although five species, each represented by a single specimen, may be regarded as vagrants, no other state has a bat fauna more diverse, from the state’s most common species, the Brazilian free-tailed bat, to the rare hairy-legged vampire.

The introductory chapter of this new edition of Bats of Texas surveys bats in general—their appearance, distribution, classification, evolution, biology, and life history—and discusses public health and bat conservation. An updated account for each species follows, with pictures by an outstanding nature photographer, distribution maps, and a thorough bibliography. Bats of Texas also features revised and illustrated dichotomous keys accompanied by gracefully detailed line drawings to aid in identification. A list of specimens examined is located at batsoftexas.com.
