GOLDEN EAGLE
A.O.U. 349. |
(Aquila chrysaetos canadensis) |
Resident. |
It is hard to estimate how common, or rare, the eagles are in the
park. They are creatures of the clouds and highest peaks. From park
records the golden eagle is mere commonly found on the bare, grassy
slopes of the north and east sides. Taylor and Shaw record them "at
intervals all around the mountain". A pair were seen by the writer over
Stevens' Canyon on May 24, 1937. On July 23, 1937, two immature birds,
probably out of the same nest, were observed playing in the air over
Cowlitz Park. They would circle and dive at each other, and would
sometimes dive together. The exhibition lasted some ten minutes and the
white, immature markings were easily identified. On October 19, 1937, a
bird was observed hunting over a rock slide at the Colonnades.
The food of these eagles in the park consists chiefly of rodents and
other small animals. Of these the marmot is undoubtedly the most hunted
in summer.
A naturalist friend of mine once told me he was resting on a high
rocky plateau on Mt. Baker, observing at the time a large marmot
stretched out on a rook. Presently a golden eagle passed a quarter of a
mile beyond, seemingly taking no notice of the marmot and descending out
of sight down the hillside. In a few moments there was a roar of wings,
the eagle passed over the watcher's head and struck the marmot with such
force and speed that the bird continued onward some 150 yards before
turning to secure his prey. Such is the power of the King of Birds!
Adult golden eagles can be told from the bald eagle by the lack of
white head and tail. The immature golden eagle has the upper half of the
tail white, lacking in the immature bald eagle.
Eagles will return to the same nest (or aerie) year after year unless
disturbed. Two or three eggs are the usual number. They are dirty-white
in color with brownish stains.

SOUTHERN BALD EAGLE
A.O.U. 352. |
(Haliaeetus l. leucocephalus) |
Resident. |
Other common names: Bird of Washington; Gray Eagle, second year;
Black Eagle, first year.
The bald eagle is probably a more common bird in the park than the
golden eagle - at least it is more easily recognized with its white head
and tail. Again, they are more attracted by water so that we may expect,
and do find them at lower levels in and out of the park. In the fall the
salmon running in the rivers attract these eagles, and they become
fishermen.
Dropping down on the slowly dying fish, they grasp their prey with
strong talons, and with mighty wing-beats drag their meal ashore to
enjoy a feast complete. The Ohanapecosh and Cowlitz Rivers just outside
the park are favorite feeding grounds when the salmon are running.
The bald eagle (emblem of our country) measures up with his royal
cousin, the golden eagle, in size and power of flight. At their best
they are seen over some peak facing a strong wind or gale. Here they
spend time and energy seemingly for pleasure, fighting the unseen power.
At times they remain stationary, then with a scream and glide they press
forward, defying the elements.
On a summer's day in 1935 an adult bald eagle was observed circling
high over the ice fields of Rainier. Higher and higher it climbed until
it seemed directly over the peak. Upward it went until out of sight even
with the aid of binoculars - an inspiring sight and a sublime exhibition
of freedom.
Bald eagles nest early and in the west they often choose our tallest
fir trees as well as the cliffs for the nesting sites. As they return
year after year to the same site unless disturbed, the repairing and
addition each year changes the original "bundle of sticks" to an immense
mass or collection, so great that in many places the high tree finally
dies and later crashes earthward.
By the highway approaching the Ohanapecosh entrance stands a tall
fir, the top of which hangs directly over the roadway. Near the top is
an old eagle's nest, now deserted. An old timer informed me that it had
been there over 40 years. Estimating its size from below, it looked
about 10 feet across and 8 feet high.
