Publisher description
A comprehensive examination of the molt processes (feather growth) of different species of birds, one of the most important and fundamental processes in the life history of any bird.
This ambitious volume covers the 36 species of gulls that occur in North and South America, with detailed information to help you identify these fascinating but challenging birds in their many and varied plumages. With 1,160 carefully chosen color photographs, this new reference guide, written by two of North America's top gull experts, is the definitive new work on gulls of the Americas. Peterson Reference Guides offer authoritative, comprehensive information, including detailed text, maps, and superior illustrations. Written by expert authors, the guides are an unparalleled resource for understanding specific groups of animals.
Sparrows are as complicated as they are common. This is an essential guide to identifying 76 kinds, along with a fascinating history of human interactions with them. What, exactly, is a sparrow? All birders (and many non-birders) have essentially the same mental image of a pelican, a duck, or a flamingo, and a guide dedicated to waxwings or kingfishers would need nothing more than a sketch and a single sentence to satisfactorily identify its subject. Sparrows are harder to pin down. This book covers one family (Passerellidae), which includes towhees and juncos, and 76 members of the sparrow clan. Birds have a human history, too, beginning with their significance to native cultures and continuing through their discovery by science, their taxonomic fortunes and misfortunes, and their prospects for survival in a world with ever less space for wild creatures. This book includes not just facts and measurements, but stories--of how birds got their names and how they were discovered--of their entanglement with human history.
With more than 700 color paintings arranged by families for quick comparison of similar species, and with detailed information on range, habitat, size, and voice, this field guide describes and illustrates 1,038 species of Mexico, Guatemala, Belize, and El Salvador.

A comprehensive field guide to the nests and nesting behavior of North American birds Beyond being a simple reference book, the Peterson Field Guide to North American Bird Nests is a practical, educational, and intimate doorway to our continent’s bird life. The diversity of nests and nesting strategies of birds reflect the unique biology and evolution of these charismatic animals. Unlike any other book currently on the market, this guide comprehensively incorporates nest design, breeding behavior, and habitat preferences of North American birds to provide the reader with a highly functional field resource and an engaging perspective of this sensitive part of a bird’s life cycle.

A highly visual guide to identifying birds in the field based on the important, unchanging features of size, shape, structure, and behavior Birding is an extremely rewarding and fun hobby, but some situations can be frustrating or unsuccessful because of a variety of challenging viewing conditions. This guide to identifying birds offers the holistic “birding by impression” method, which not only helps with these difficult conditions, but also develops an efficient mental identification process using left- and right-brain skills. It begins with a conscious assessment of a bird’s unchanging physical characteristics, including general size, body shape, structural features (bill, legs, neck, and wings), and behavior. Using this approach, birders can quickly assess all birds and distinguish new and uncommon species from familiar ones. They can then examine more detailed field marks to fine-tune the identification. Rather than a traditional field guide, this book presents an interactive how-to approach to a more complete identification process.
