There are thousands of moth species in the northeast of North America, and while it might seem that they are all drab grays and browns, there is actually a startling variety. They come in a rainbow of colors, from brilliant oranges and pinks to soft greens and violets. There are moths with colorful leopard-like spots, and ones that look more like B-movie aliens; some that are as large as your hand, and others the size of a grain of rice. With helpful tips on how to attract and identify moths, range maps and season graphs showing when and where to find each species, and clear photographs that use the unique Peterson arrow system for easy identification, this guide provides everything an amateur or experienced moth-watcher needs.

This book describes the major plant and animal components of Spring Creek Prairie Audubon Center, an 850-acre National Audubon Society tallgrass prairie in Lancaster County, southeastern Nebraska. In addition to providing a species list of the area's plants (368 species), there are comprehensive annotated lists of its birds (240), mammals (43), reptiles (23), and amphibians (10). There are also variably complete annotated lists of the area's butterflies (76), sphinx moths (30), silk moths (7), dragonflies (24), damselflies (11), grasshoppers (9), katydids (11), mantids (2), and walkingsticks (2). Brief profiles of life histories and ecologies of 55 animal and 7 plant species are included, as well as information on nearly 100 public-access native grasslands in eastern Nebraska. The text comprises more than 68,000 words, 400 references, and a glossary of 125 biological/scientific terms as well as more than 40 line drawings by the author.
A comprehensive field guide that uses an innovative Sound Index to allow readers to quickly identify unfamiliar songs and calls of birds in western North America. Bird songs and calls are at least as important as visual field marks in identifying birds. Yet short of memorizing each bird’s repertoire, it’s difficult to sort through them all. Now, with the western edition of this groundbreaking book, it’s possible to visually distinguish bird sounds and identify birds using a field-guide format. At the core of this guide is the spectrogram, a visual graph of sound. With a brief introduction to five key aspects—speed, repetition, pauses, pitch pattern, and tone quality—readers can translate what they hear into visual recognition, without any musical training or auditory memorization. The Sound Index groups similar songs together, narrowing the identification choices quickly to a brief list of birds that are likely to be confused because of the similarity of their songs. Readers can then turn to the species account for more information and/or listen to the accompanying audio tracks available online. Identifying birds by sound is arguably the most challenging and important skill in birding. This book makes it vastly easier to master than ever before.
