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.
