These superb collections of field recordings and descriptions offer unparalleled access to the sounds and calls of numerous popular and less well known birds and amphibians. Each book and CD provides an introduction to the sound repertoire of species living in eastern and central North America--a variety of calls from each species are included, along with an in-depth description and explanation of their significance. In addition to color photographs of the most common species, the text offers a fascinating look at the science of avian and amphibian calls, making these guides indispensable aids for the outdoor enthusiast.
In this eloquent plea for compassion and respect for all species, journalist and gardener Nancy Lawson describes why and how to welcome wildlife to our backyards. Through engaging anecdotes and inspired advice, profiles of home gardeners throughout the country, and interviews with scientists and horticulturalists, Lawson applies the broader lessons of ecology to our own outdoor spaces. Detailed chapters address planting for wildlife by choosing native species; providing habitats that shelter baby animals, as well as birds, bees, and butterflies; creating safe zones in the garden; cohabiting with creatures often regarded as pests; letting nature be your garden designer; and encouraging natural processes and evolution in the garden. The Humane Gardener fills a unique niche in describing simple principles for both attracting wildlife and peacefully resolving conflicts with all the creatures that share our world.
Covering all 101 species of frogs in the United States and Canada, this book contains natural history information, identification tips, range and habitat information, summaries of behavior, and descriptions of calls. A 70-minute audio compact disc includes the calls of nearly every species.
Frogs of Southern Africa - a Complete Guide is an authoritative and comprehensive guide that covers all aspects of frog and toad biology and behaviour. Now updated and including recently discovered species, it has a fascinating introduction that unpacks frog biology, along with a full illustrated identification key. Stunning full-colour photographs of both frogs and tadpoles accompany distribution maps and authoritative text for each species; and QR codes link readers directly to their frog calls.
In a Panamanian pond, male túngara frogs (Physalaemus pustulosus) gather in choruses, giving their "advertisement" call to the females that move among them. If a female chooses to make physical contact with a male, he will clasp her and eventually fertilize her eggs. But in vying for the females, the males whose calls are most attractive may also attract the interest of another creature: the fringe-lipped bat, a frog eater. In the Túngara Frog, the most detailed and informative single study available of frogs and their reproductive behavior, Michael J. Ryan demonstrates the interplay of sexual and natural selection. Using techniques from ethology, behavioral ecology, sensory physiology, physiological ecology, and theoretical population genetics in his research, Ryan shows that large males with low-frequency calls mate most successfully. He examines in detail a number of explanations for the females' preferences, and he considers possible evolutionary forces leading to the males' success. Though certain vocalizations allow males to obtain mates and thus should be favored by sexual selection, this study highlights two important costs of such sexual displays: the frogs expand considerable energy in their mating calls, and they advertise their whereabouts to predators. Ryan considers in detail how predators, especially the frige-lipped bat (Trachops cirrhosus), affect the evolution of the túngara frog's calls.

Crawfish Frogs (Rana areolata) have been called the most secretive frog in North America, and it is unusual in the twenty-first century – in the most scientifically advanced country in the world – that basic discoveries can still be made on an animal that inhabits a quarter of the United States. This is not only a story of the biology of Crawfish Frogs, but a case study of discovery. This volume describes the life history and natural history critical to the survival of the endangered amphibian and recommends management actions to ensure persistence. The authors tell an optimistic conservation biology story and fill a gap between science and the public. The authors have compiled and summarized the peer-reviewed literature on the biology of Crawfish Frogs, which may be one of the most interesting frogs in North America (that nobody knows about).

Frogs are amazingly diverse—ranging from the massive goliath frog, which weighs several pounds, to the recently discovered gold frog, which measures a mere three-eighths of an inch when fully grown—and have inhabited the earth for more than 200 million years. Today, however, these amphibians face more challenges than any other vertebrate group. In this fun and informative book, herpetologists Mike Dorcas and Whit Gibbons answer common and not-so-common questions people may have about these fascinating animals. Dorcas and Gibbons discuss how frogs evolved, which species currently exist in the world, and why some have recently gone extinct. They reveal what frogs eat and what eats them, their role in cultures across the globe, why many populations are declining and what we can do to reverse this dangerous trend, why there are deformed frogs, and much more. They answer expected questions such as “What is the difference between a frog and a toad?” and “Why do some people lick toads?” and unexpected ones such as “Why do some frogs lay their eggs in the leaves of trees?” and “Do frogs feel pain?” The authors’ easy-to-understand yet thorough explanations provide insight into the amazing biology of this amphibian group. In addressing conservation questions, Dorcas and Gibbons highlight the frightening implications of the current worldwide amphibian crisis, which many scientists predict will bring extinction rates experienced by frog species to levels not seen in any vertebrate animal group in millions of years. Packed with facts and featuring two color galleries and 70 black-and-white photographs, Frogs: The Animal Answer Guide is sure to address the questions on the minds of curious naturalists.
