Who
Are You Calling Bald?
From a distance, the majestic bald eagle does indeed appear to be
bald. In reality, this large raptor has white feathers on
the head, neck, and tail. To early colonists the word "bald"
meant white, not bare. In 1782, the US Congress selected the bald
eagle as our national symbol.

Bringing
Home The Dinner
Bald eagles are skilled predators over land and water. These
diurnal hunters use their keen vision to spot prey two or
three times farther away than people can see. After catching a meal,
usually fish, eagles quickly kill the animal with their grasping
feet and dagger-like talons. Flying to a favorite perch or lookout,
eagles will use their sharply hooked beaks to snip and pluck the
feathers or fur away. If the prey is a small animal, eagles will
swallow it whole but they tear off mouth-sized chunks of larger
food. Bones, feathers, and hair that cannot be easily digested are
later regurgitated. These competent sea eagles are capable
of spotting and snatching fish directly from the water's surface.
Eagles are also scavengers that search the waterways and highways
for dead carcasses. This method of finding food saves time and energy,
and cleans the ecosystem all at the same time.

The
Biggest Bed Around!
A bald eagle couple builds a nest a few feet below the top of
a living tall tree or on a rocky outcrop. They choose an open site
so they have a clear view of the neighborhood as well as an unobstructed
flight pad. Eagles mate for life and will return to the same nest
year after year, adding fresh sticks and greenery until the nest
may weigh over a ton, stand 12 feet high, and measure eight feet
across! Parent birds take turns incubating their clutch of
one to three eggs and both adults feed and brood the eaglets
until they are ready to fledge. During the years when prey
is scarce, the largest chick may claim so much of the food that
its siblings could perish. This may seem unfair but at least
one strong eaglet will survive to grow up and join the population.

Conservation:
There's Still Time
Bald eagles and other birds of prey face many perils. For nearly
a century there was a bounty on eagles because they were
unfairly blamed for killing livestock and competing with fishermen.
In the 1940's the pesticide DDT decimated many eagle, osprey,
and brown pelican populations. This chemical collected in their
bodies after they ate contaminated fish. Although the insecticide
did not always kill the birds, it caused them to lay thin-shelled
eggs. The parents crushed the eggs during incubation. No eggs, no
hatchlings, no birds for the future. Power lines, discarded fishing
line, poison baited traps, vehicles, and destruction of mature trees
and wetlands have also contributed to the eagles' decline. Since
the United States' government banned DDT and passed protective wildlife
laws, our national symbol has begun to recover. When people care,
endangered species survive.
