The tiny hummingbird has long been a source of fascination for birdwatchers and naturalists alike. They number 300 species and Ronald Orenstein has a passion for all of them.
Hummingbirds are the smallest birds in the world. A hummingbird egg is the size of a pea, barely, and the chick that emerges will be smaller than a penny, if that. But these tiny birds pack a powerful engine: a hummingbird's heart beats more than 1200 times per minute.
Nicknamed the "avian helicopter", a hummingbird's wings beat from 70 times per second in direct flight, to more than 200 times per second when diving. Not surprisingly, that whirlwind of wing power creates a humming sound. To fuel such energy, hummingbirds must eat as much as eight times their body weight on a daily basis, which means visiting an average of 1000 flowers – every day – to get enough nectar.
Hummingbirds are found in North and South America, with the greatest number in Ecuador, although some species breed as far north as Canada. Most species migrate from Mexico to Alaska, a distance of more than 5000 miles.
In Hummingbirds Orenstein covers all aspects of hummingbird natural history, their relationship with the plants on which they feed, the miracle of their flight, their elaborate social life and nesting behaviour, and their renowned feats of migration.
More than 170 colour photographs of these magnificent creatures, taken in the wild, adorn the pages of Hummingbirds. Birders and natural history readers alike will gain new insight into the tiny bird and revel in the stunning images.
Ronald Orenstein is a zoologist, lawyer, wildlife conservationist and an award-winning science author. He has written extensively on a wide range of natural history issues, including as a contributing author to Handbook of the Birds of the World. His most recent books are Turtles, Tortoises and Terrapins and Ivory, Horn and Blood. He is a member of the International Union for Conservation of Nature.
Michael and Patricia Fogden are widely considered the world's finest photographers of hummingbirds. They live in Costa Rica.
"There are many, many hummingbird books. But Hummingbirds stands out as a book that celebrates and explains, in both words and images, how wonderfully unique these birds are. I wish that its extensive portfolio had more diversity, but this is still the most impressive collection of hummingbird photographs that I’ve ever seen. Whether you want to learn more about these birds, see some insanely good pictures, or both, this is your book."
