PASSAGE 1
|
Hummingbirds are small, often
brightly colored birds of the family Trochilidae that live exclusively in the
Americas. About 12 species are found in North America, but only the ruby-throated
hummingbird breeds in eastern North America and is found from Nova Scotia to
Florida. The greatest variety and number of species are found in South America.
Another hummingbird species is found from southeastern Alaska to northern California.
Many hummingbirds are minute. But even the giant
hummingbird found in western South America, which is the largest known hummingbird, is only
about 8 inches long and weighs about two-thirds of an ounce. The smallest
species, the bee hummingbird of Cuba and the Isle of Pines, measures slightly
more than 5.5 centimeters and weighs about two grams.
Hummingbirds’ bodies are compact,
with strong muscles. They have wings shaped like blades. Unlike the wings of
other birds, hummingbird wings connect to the body only at the shoulder
joint, which allows them to fly not only forward but also straight up and
down, sideways, and backward. Because of their unusual wings, hummingbirds
can also hover in front of flowers so they can suck nectar and find insects.
The hummingbird’s bill,
adapted for securing nectar from certain types of flowers, is usually rather long
and always slender, and it is curved slightly downward in many species.
The hummingbird’s body feathers
are sparse and more
like scales than feathers. The unique character of the feathers produces brilliant
and iridescent colors, resulting from the refraction of light by the
feathers. Pigmentation of other feathers also contributes to the unique color
and look. Male and female hummingbirds look alike in some species but different
in most species; males of most species are extremely colorful.
The rate at which a hummingbird
beats its wings does not vary, regardless of whether it is flying forward,
flying in another direction, or merely hovering. But the rate does vary with
the size of the bird — the larger the bird, the lower the rate, ranging from
80 beats per second for the smallest species to 10 times per second for
larger species. Researchers have not yet been able to record the speed of the
wings of the bee hummingbird but imagine that they beat even faster.
Most hummingbirds, especially the
smaller species, emit scratchy, twittering, or squeaky sounds. The wings, and
sometimes the tail feathers, often produce humming, hissing, or popping
sounds, which apparently function much as do the songs of other birds.
