Review "Even a professional ornithologist would enjoy this booklet. A surprisingly large range of topics are covered in the book， including (to list but a few) anatomy， breeding， coevolution of hummingbirds and flowers， migrathion， and how to attract the birds." --South Dakota Bird Notes (South Dakota Ornithologist's Union) Product Description There is a sense of mystery that surrounds hummingbirds: Why are they so small? What makes it possible for them to hover? Why are they so colorful? Do they ever rest? This book gives the often amazing answers. The Secret Lives of Hummingbirds takes the reader into the high-energy world of North America's smallest bird. Hearts that beat 500 to more than 1200 times per minute. Wings that buzz at as much as 52 beats per second. And respiration that can clock in at up to 600 breaths per minute. But their energetic lifestyle is only one facet of the secret lives of hummingbirds. Illustrated with twenty-nine full-color photographs， The Secret Lives of Hummingbirds is a treat for birders， naturalists， or anyone else who can't resist the allure of these eye-catching， pugnacious miniature birds. The book also includes a close-up look at the Desert Museum's famous hummingbird aviary as well as tips on how to enjoy and attract wild hummingbirds. It's no wonder that The Secret Lives of Hummingbirds is our most popular publication! See all Editorial Reviews
