Why Birds Matter
Ecological, Economic, and Aesthetic Importance
of Birds
Ecological Importance
“Spring would not be spring without
bird songs.”
Theodore Roosevelt

Wild birds are essential components of
healthy, functioning natural systems. They pollinate flowers,
disseminate seeds, and help keep insect populations under
control.
Like the proverbial canaries in a coal
mine, birds also serve as indicators of the ecological health
of our planet. Because of their rapid metabolism and wide geographic
distribution, birds provide early warning to us of changes in the environment and potentially
harmful biological conditions.
Robust, diverse bird populations reflect
the underlying health of the ecosystem in which they—and
we—live. When a wetland begins to lose its ducks, herons,
and swallows, it’s a signal that water quantity and
quality are declining, which bodes ill for other species such
as salmon and people. Since we share our planet with all other
species, what happens to birds will happen to us.
Economic Importance
“Kill not the goose that lays
the golden egg.”
— English proverb
Birds save money. Without the environmental
assistance we get from birds, we would have to spend far more
money on pest control and keeping natural systems in balance.
Insect-eating birds on farms, in woodlands, and in cities
reduce the need for chemical pest control. Birds are also
voracious eaters of weed plants and nuisance rodents. They
provide us with “free ecological services” and
are unheralded assistants to farmers, foresters, and gardeners.
Birds make money. Bird watching
is the fastestgrowing form of outdoor recreation in the United
States, up 155 percent in the last ten years. In 2001 more
than 46 million Americans watched birds and spent more than
$32 billion on the pastime. People travel to see birds, buy
backyard bird feeders, plant gardens for birds, and spend
money to support bird research and protect bird habitat.
Birders attract money to Washington.
The economic impact from birders and watchable wildlife enthusiasts
is astounding. The latest report from the Washington Department
of Fish and Wildlife shows that wildlife watching provides
more than 22,000 jobs and brings in $980 million to the state
annually, compared to $350 million from hunting and $854 million
from recreational fishing. Most birders are well educated,
have annual incomes greater than $30,000, and are willing
to spend money to watch birds. When birders go on overnight
bird-watching trips, they typically spend $100 to $130 per
day.
Aesthetic Importance
“Keep a green bough in your heart
and the singing bird will come.”
– Chinese proverb
Birds populate our fields and forests
and waters as well as our books and plays and paintings. They
awaken the poet and artist and philosopher in each of us,
and we celebrate their beauty and power of flight. They help
our spirits soar, our visions broaden – and they renew
our natural sense of joy and wonder. |
