From the African long-tongued fruit bat to the wrinkle-faced bat of Mexico and Central America, Walker's Bats of the World is an astonishingly complete guide to this fascinating, beneficial, and varied order of mammals. It includes scientific and common names, as well as the number and distribution of species, measurements and physical traits, habitat, daily and seasonal activity, population dynamics, home range, social life, reproduction, and longevity. Textual summaries present accurate, well-documented descriptions of the physical characteristics and living habits of bats in every part of the world. Endangered species and those having singular economic importance are given particular attention.
Through five highly praised editions Walker's Mammals of the World has remained the most comprehensive―the preeminent―reference work on mammals. Now for the first time a single large segment of that encyclopedic work―the section on Chiroptera, or bats―is available in paperback as a separate volume. Lavishly illustrated with pictures by noted wildlife photographers, the book includes photographs of many rarely seen bats. As in the complete Walker's Mammals, most photographic illustrations depictlive animals rather than skins or skeletons.
Since publication of the first edition in 1964, Walker's Mammals of the World has become a favorite guide to the natural world for general readers and an invaluable reference for professionals. Now Walker's Bats makes a significant portion of that work accessible to a new audience

From Nigeria's needle-clawed bush baby to the snub-nosed langur of Tibet, from loris to lemur, from the woolly monkey to the "naked ape," primates are among the world's most diverse―and distinctive―groups of mammals. Seventy million years of evolving primate anatomy (much of it significantly influenced by a tree-dwelling lifestyle) has resulted in such defining characteristics as stereoscopic vision, a relatively large brain, grasping hands and feet, and superior levels of dexterity and muscular coordination.
Now Ronald M. Nowak offers a comprehensive guide to this fascinating and varied order of mammals. Walker's Primates of the World includes scientific and common names, the number and distribution of species, measurements and physical traits, habitat, daily and seasonal activity, population dynamics, home range, social life, reproduction, longevity, and status of threatened species. Recently extinct genera, such as the giant lemurs of Madagascar, are covered in full. Textual summaries present accurate, well-documented descriptions of the physical characteristics and living habits of primates in every part of the world.
In a new introduction, noted primate conservationists Russell A. Mittermeier, Anthony B. Rylands, and William R. Konstant discuss the taxonomy and distribution of primates as well as their distinguishing characteristics, special adaptations and particularly striking features, such as sociality. They also report on conservation efforts past and future, and assess the factors, largely human-caused, that are threatening non-human primates with extinction.

Walker's Carnivores of the World

Although they are highly intelligent, ruthless predators, carnivores are increasingly rare. From the dwarf mongoose to the polar bear, carnivores are at once respected and misunderstood, invoking both fear and curiosity in the humans with whom they share their world. Ronald M. Nowak celebrates these fascinating mammals in Walker's Carnivores of the World. This comprehensive guide, featuring 225 illustrations, covers the world's eight terrestrial families of carnivores. Each generic account comprises scientific and common names, number and distribution of species, physical attributes, measurements, hunting and social activity, reproduction, habitat, population dynamics, longevity, and status of threatened species. A thought-provoking overview by David W. Macdonald and Roland W. Kays is packed with results of the latest field and laboratory research on topics ranging from evolutionary history to the adaptive value of fur patterns. Emphasizing the interplay of social life, morphology, and predatory behavior, it provides an up-to-date panorama of the world's carnivores.

Biological Sciences

Authoritative and engaging, this volume from the Walker's Mammals series focuses on marsupials, pouched animals whose unusual method of reproduction―between egg laying and placental birth―places them in a unique category among mammals. 
A comprehensive guide to the biology and distribution of marsupials, this book includes common and scientific names, size and physical traits, habitat and ecology, behavior and social interactions, reproduction, life span, and conservation. The text is coupled with illustrations from the collections of leading photographers and the world's greatest museums. An introduction by marsupial expert Christopher R. Dickman describes the evolution and current status of marsupials and reveals why they add so much intrigue to the natural world.

Excerpt from North American Quaternary Canis The research required in preparation of this paper necessitated considerable travel to museums and other localities throughout North America. I therefore am especially grateful to those organizations that aided me in this regard. The Theodore Roosevelt Me morial Fund of the American Museum of Natural History, and the National Science Foundation each made a direct grant for travel and related expenses. The Committee on Systematics and Evolutionary Biology, University of Kansas, provided travel grants in 1970 and 1971, a research assistantship in the summer of 1972, and also a traineeship for the academic year 1971-1972. No progress could have been made in my research had it not been for the cooperation of numerous persons who generously assisted me in the examination of specimens and asso ciated materials in their care. I want to especially thank John L. Paradiso, Bird and Mammal Laboratories, United States National Museum of Natural History (now of the Office of Endangered Species, us. Fish and Wildlife Service). During the four months that my wife and I worked at the National Museum, he aided us in every 'way possible and spent a great deal of his own time to see that we were well provided for both in and out of the Museum. John and I actually have been in close communication regarding Cam's since 1965. Many of the views expressed in this paper were developed jointly with him in the course of years of pleasant study, con versation, and correspondence. I am also grateful to the following per sons who either sent me specimens on loan or assisted me when I visited their areas: Sydney Anderson, American Museum of Nat ural History; Rollin H. Baker, The Museum. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

The preeminent guide to the world’s mammals is now enhanced with a dramatically expanded volume covering 19 orders, including such creatures as elephants, armadillos, and manatees.
Since its first publication in 1964, Walker's Mammals of the World has become a favorite guide to the natural world for general readers and professionals alike. This new Walker's volume is a completely revised and updated compendium of information on five of the earliest clades to diverge from ancient mammal stock. Uniquely comprehensive in inimitable Walker's style, it incorporates a full account of every genus that has lived in the past 5,000 years. Every named species of each genus is listed in systematic order and accompanied by detailed descriptions of past and present range. 
This new edition includes • 500+ full-color images throughout • citations to more than 2,200 new references • extensive bioconservation data, with discussion of every species in an IUCN Red List threatened category
This volume's thorough updates reflect 20 years of advances in our knowledge of taxonomy, ecology, behavior, life history, and conservation. Substantive changes to 100% of previously existing generic accounts, plus the addition of 17 entirely new generic accounts, double the information in the last edition on the 19 orders covered. The black-and-white illustrations of earlier editions have been replaced by over 500 superb new color images. 
Remaining true to Ernest P. Walker's vision, the text smoothly combines in-depth scholarship with a popular, readable style to preserve and enhance what the Washington Post called a "landmark of zoological literature."
