National Geographic’s Field Guide to the Birds of North America is the noted authority among birding guides. These pocket guides build on that reputation. It features images of world renowned birding photographers Tom Vezo, Bates Littlehales, among others. It includes customised maps that show the specific range of each bird during winter months, breeding months, and during migration. This book, Arizona and New Mexico , joins Washington and Oregon as the 4th set in the series of pocket-size bird field guides, which began with the launch of the first two guides - California and Florida - in Spring 2005. Each guide is 272 pages and will feature about 175 birds - either as a main entry or secondary entry. The book’s 4X6 trim fits in a backpack or pocket for easy access. Arizona and New Mexico are year-round birding spots. Southeast Arizona is among the top 10 top birding sites in America - known as the number one hummingbird spot, where a dozen or more species can be sighted at a time. Birds from deserts and mountains in both states include the Elegant Trogon - related to the famed Resplendent Quetzal of Central America, the Painted Redstart, the cardinal-like Pyrrhuloxia, and the endearing Roadrunner, a desert-running cuckoo.
