Bat biologist Barbara A. Schmidt-French and writer Carol A. Butler offer a compendium of insightful facts about bats in this accessible and expertly written question-and-answer volume. Numbering more than one thousand species in our world today, bats in the wild are generally unthreatening. Like most other mammals, bats are curious, affectionate, and even playful with one another.

Highly beneficial animals, bats are critical to global ecological, economic, and public health. Do Bats Drink Blood? illuminates the role bats play in the ecosystem, their complex social behavior, and how they glide through the night sky using their acute hearing: echolocation skills that have helped in the development of navigational aids for the blind. Personal in voice with the perspective of a skilled bat researcher, this book explores wide-ranging topics as well as common questions people have about bats, providing a trove of fascinating facts.

Featuring rare color and black-and-white photographs, including some by renowned biologist, photographer, and author Merlin Tuttle, Do Bats Drink Blood? provides a comprehensive resource for general readers, students, teachers, zoo and museum enthusiasts, farmers and orchardists, or anyone who may encounter or be fascinated by these extraordinary animals.

How fast do butterflies fly? Does a butterfly have ears? Do they sleep? Does a caterpillar have a skeleton? How does a moth get out of its cocoon? What is the difference between a butterfly and a moth? And just what is a skipper?

Every year, thousands of people visit butterfly conservatories to stand in quiet awe of the simple beauty displayed by these magical creatures. Hazel Davies and Carol A. Butler capture the sense of wonderment and curiosity experienced by adults and children alike in this book about butterflies and their taxonomic cousins, the moths and the skippers. Beautifully illustrated with color and black and white photographs, and drawings by renowned artist William Howe, this book is an essential resource for parents, teachers, students, or anyone who has ever been entranced by these fascinating, fluttering creatures.

Covering everything from their basic biology to their complex behaviors at every stage of life to issues in butterfly conservation, Davies and Butler explore wide-ranging topics and supply a trove of intriguing facts. You'll find tips on how to attract more butterflies to your garden, how to photograph them, and even how to raise them in your own home. Arranged in a question and answer format, the book provides detailed information written in an accessible style that brings to life the science and natural history of these insects. In addition, sidebars throughout the book detail an assortment of butterfly trivia, while extensive appendices direct you to organizations, web sites, and more than 200 indoor and outdoor public exhibits, where you can learn more or connect with other lepidopterophiles (butterfly lovers).

Hummingbirds may be the smallest birds in the world, but they have the biggest appetites. Their wings flutter on average fifty to eighty times each second as they visit hundreds of flowers over the course of a day to sip the sweet nectar that sustains them. Their hearts beat nearly twelve hundred times a minute and their rapid breathing allows these amazing birds to sustain their unique manner of flight. They can hover in the air for prolonged periods, fly backwards using forceful wings that swivel at the shoulder, and dive at nearly two hundred miles per hour. Native only to the Americas, some hummingbirds have been known to migrate from Mexico to Alaska in the course of a season. Watching a hummingbird at a backyard feeder, we only see its glittering iridescent plumage and its long, narrow beak; its rapidly moving wings are a blur to our eyes.

These tiny, colorful birds have long fascinated birders, amateur naturalists, and gardeners. But, do they really hum?

In Do Hummingbirds Hum? George C. West, who has studied and banded over 13,500 hummingbirds in Arizona, and Carol A. Butler provide an overview of hummingbird biology for the general reader, and more detailed discussions of their morphology and behavior for those who want to fly beyond the basics. Enriched with beautiful and rare photography, including a section in vivid color, this engaging question and answer guide offers readers a wide range of information about these glorious pollinators as well as tips for attracting, photographing, and observing hummingbirds in the wild or in captivity.

The social survey has become an essential tool in modern society, providing crucial measurements of social change, describing social life, and guiding government policy. But the validity of surveys is fragile and depends ultimately upon the accuracy of answers to survey questions. As our dependence on surveys grows, so too have questions about the accuracy of survey responses. Authored by a group of experts in cognitive psychology, linguistics, and survey research, Questions About Questions provides a broad review of the survey response problem. Examining the cognitive and social processes that influence the answers to questions, the book first takes up the problem of meaning and demonstrates that a respondent must share the survey researcher's intended meaning of a question if the response is to be revealing and informative. The book then turns to an examination of memory. It provides a framework for understanding the processes that can introduce errors into retrospective reports, useful guidance on when those reports are more or less trustworthy, and investigates techniques for the improvement of such reports. Questions about the rigid standardization imposed on the survey interview receive a thorough airing as the authors show how traditional survey formats violate the usual norms of conversational behavior and potentially endanger the validity of the data collected. Synthesizing the work of the Social Science Research Council's Committee on Cognition and Survey Research, Questions About Questions emphasizes the reciprocal gains to be achieved when insights and techniques from the cognitive sciences and survey research are exchanged. "these chapters provide a good sense of the range of survey problems investigated by the cognitive movement, the methods and ideas it draws upon, and the results it has yielded." —American Journal of Sociology

Twenty-five thousand species of bees certainly create a loud buzz. Yet silence descended a few years ago when domesticated bee populations plummeted. Bees, in particular honey bees, are critical links in the vibrant chain that brings fruits, vegetables, and nuts to markets and dinner tables across the country. Farmers and scientists on the agricultural frontlines quickly realized the impact of this loss, but many others did not see this devastation.

Why Do Bees Buzz? reports on the mysterious "colony collapse disorder" that has affected honey bee populations, as well as other captivating topics, such as their complex, highly social lives, and how other species of bees are unique and different from honey bees. Organized in chapters that cover everything from these provocative pollinators' basic biology to the aggressive nature of killer bees, this insightful question and answer guide provides a honeycomb of compelling facts.

With clarity and depth, bee biologist Elizabeth Capaldi Evans and coauthor Carol A. Butler examine the lives of honey bees, as well as other species such as orchid bees, bumblebees, and stingless bees. Accessible to readers on every level, and including the latest research and theory for the more sophisticated reader, the authors reveal more than one hundred critical answers to questions about the lives of bees.

Concepts about speciation, evolutionary adaptation and pollination, as well as historical details about topics such as Mayan beekeeping and the appearance of bees in rock art, are arranged in easy-to-follow sidebars that highlight the text. Color and black and white photographs and drawings enhance the beauty and usefulness of Why Do Bees Buzz?
