Imagine a creature the size of your thumb, weighing less than a
penny, but consuming half of its weight in food each
day...Hummingbirds may be the smallest birds in the world, but they
have the biggest appetites. Their wings flutter on average fifty to
eighty times each second as they visit hundreds of flowers over the
course of a day to sip the sweet nectar that sustains them. Their
hearts beat nearly twelve hundred times a minute and their rapid
breathing allows these amazing birds to sustain their unique manner
of flight. They can hover in the air for prolonged periods, fly
backwards using forceful wings that swivel at the shoulder, and
dive at nearly two hundred miles per hour. Native only to the
Americas, some hummingbirds have been known to migrate from Mexico
to Alaska in the course of a season. Watching a hummingbird at a
backyard feeder, we only see its glittering iridescent plumage and
its long, narrow beak; its rapidly moving wings are a blur to our
eyes. These tiny, colorful birds have long fascinated birders,
amateur naturalists, and gardeners. But, do they really hum? In Do
Hummingbirds Hum? George C. West, who has studied and banded over
13,500 hummingbirds in Arizona, and Carol A. Butler provide an
overview of hummingbird biology for the general reader, and more
detailed discussions of their morphology and behavior for those who
want to fly beyond the basics. Enriched with beautiful and rare
photography, including a section in vivid color, this engaging
question and answer guide offers readers a wide range of
information about these glorious pollinators as well as tips for
attracting, photographing, and observing hummingbirds in the wild
or in captivity.
