is devoted to mammals, which are the class of vertebrate
animals possessing hair, with the females having
milk-secreting glands. One group of mammals, the
cetaceans (whales and dolphins) have a layer of blubber
instead of hair. This class, having among its
representative genera certain species that fly, others
that glide, swim, climb, burrow, leap, or run, is perhaps
the most versatile and adaptable of the vertebrate animal
with its variety of soils, climate, vegetation, and
topography, as well as extensive coastline, is the home
of more than 181 distinct species of mammals. The
locomotive versatility of the various members of the
class is responsible in part for the occurrence of
mammals in our deserts, forests, mountains, prairies,
high plains, and waters.
represents the fifth account published by the Texas Parks
and Wildlife Department detailing the kinds of mammals
that occur in Texas with information about their lives
and economic importance. Dr. W. P. Taylor and Dr. W. B.
Davis collaborated to prepare The Mammals of Texas,
published by the former Texas Game and Fish Commission as
Bulletin No. 27, in August 1947. Recognizing the growing
interest in Texas mammals and the expanding knowledge
about the many kinds of mammals in the state, Dr. Davis
in 1960 wrote an entirely new bulletin, designated as
Bulletin No. 41, which served as an identification key to
Texas mammals and also provided information on their
distribution and life histories. Dr. Davis revised
Bulletin No. 41 in 1966 and again in 1974.
supplies and increasing popularity of Bulletin No. 41
prompted the Texas Parks and Wildlife Department to seek
an updating of this informative publication. For this
purpose, wildlife expert and mammalogist Dr. David J.
Schmidly very graciously agreed to update Dr. Davis
publication and make needed revisions in the species
distribution maps and other portions of the bulletin.
Most of the changes were made to update the
identification keys and geographic ranges of mammals in
Texas and its adjacent waters. The natural history
descriptions, for the most part, remain essentially as
detailed by Dr. Davis in Bulletin No. 41.
is the basic goal in organizing this book. Accounts for
each species are arranged so that they contain in
sequence (1) a brief description of the mammal, with
special emphasis given to distinguishing features,
accompanied in most cases by a photograph; (2) a
description of the geographic distribution of the species
in Texas, with reference to a map; and (3) a discussion
of some of the basic life history of the mammal,
including habitat preferences, reproduction, behavior,
and food habits. This information has been taken from
observations recorded by other researchers and reported
in the scientific literature as well as the personal
experiences of the authors based on more than 50 years of
field work in Texas. On the distribution maps, counties
where specimens of mammals have been reported, either in
the literature or represented by a scientific specimen
located in a museum collection, are indicated by black
dots; the probable range for most species is shaded in.
of wildlife and citizens interested in conservation and
natural history will find much help in this revision of The
Mammals of Texas, by Dr. W. B. Davis (Professor
Emeritus of Wildlife and Fisheries Sciences), and Dr.
David J. Schmidly (Professor and Curator of Mammals in
the Department of Wildlife and Fisheries Sciences) of
Texas A&M University, both of whom are recognized
internationally as authorities on mammals.
