This book is the first ever, comprehensive photographic guide to the identification of all 24 species of hummingbirds to be seen as breeders or vagrants in North America.. For all their startling colours, the speed of hummingbird flight and the often drab coloration of females and immatures make this group especially difficult to deal with in the field. The simple field marks are often poorly lit, hard to spot, or simply not shown by any particular individual under observation. But accurate identification of these popular and beautiful birds brings both real satisfaction and a welcome challenge to most birders. Steve Howell, a well-known and respected bird tour leader and author, has made a particular study of the finer points of hummingbird recognition and has specially chosen over 200 stunning photographs to complement the information given in his text. Some species feature as many as 14 photographs. A detailed introduction covers the basics of hummingbird anatomy and plumage variation, allowing the observer to effectively focus on points that are of value in the field. New field marks are provided and old myths dispelled in this ground breaking and essential new guide. Key Features * Contains up to 14 full-color photos for each species, with detailed photo captions * Detailed introduction covers fundatmentals of hummingbird identification, including discussions of anatomy, plumage variation, and molt * Comprehensive species accounts describe all plumages, compare similar species in depth, and discuss voice, displays, behavior, geographic range, and seasonal distribution * Emphasizes difficult to identify plumages, such as females and immatures * Features 200 stunning photos picked specifically to show identification criteria

Designed to help birders and banders identify, age, and sex all seventeen species of hummingbirds found in North America, this is the only identification guide devoted entirely to hummingbirds that includes up-close, easy-to-use illustrations. It also provides information on the eight species that have been reported but rarely seen in North America. On first viewing hummingbirds are often a blur of fast-moving color. However, when they perch and hover they can be observed, and the size, shape, and color; the proportions of the body, bill, throat, and tail; the wing feather pattern; and the birds’ behavior are crucial to accurate identification. The author’s concise descriptions and illustrations pinpoint all these features in clear, jargon-free language. Anyone who loves hummingbirds will welcome the information he provides.

The first comprehensive guide to the sounds of eastern North American birds, featuring an innovative visual index that allows readers to quickly look up unfamiliar sounds in the field.​ Bird songs and calls are just as important as visual field marks in identifying birds. But until now, the only way to learn them was by memorization. With 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 learn to visualize sounds, without any musical training or auditory memorization. Picturing sounds makes it possible to search this book visually for a bird song heard in the field. The Sound Index groups similar songs together, narrowing the identification choices quickly to a brief list of birds that sound alike. Readers can then turn to the species account for more information and/or listen to the accompanying audio tracks available online, through Cornell's Lab of Ornithology. 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.
