Eagles are born to soar. They rule the sky over mountains, scrubland, lakes and oceans’ edges. Both bald and golden eagles grace the West.

Raptors and birds of prey specialize in hunting and eating meat. They have dagger-clawed feet called talons that are designed to grasp and pierce. Their hooked beaks are suited to tearing carcasses apart.

They have binocular vision, eyes oriented towards the front rather than the side, which are five to six times stronger than human eyes. They are routinely able to spot small mammals from a mile away from the sky.

The eagle’s ability to soar is legendary. They are experts at reading landforms and finding updrafts and thermals — those spiraling columns of warm air that rise to considerable heights and are often topped by cumulus clouds.

Both golden and bald female eagles are slightly larger than the respective males. Females weigh 13 pounds and males reach 10 pounds and both have 7.5 feet wingspans. The eagle is the largest raptor in North America.

The golden is known for its excellence in flight and is named after its regal mantle of feathers on its crown and neck. Its feathers extend right down to its toes. Meanwhile, the bald eagle, like other sea-eagles, has bare legs.

Golden eagles are synonymous with the high country. In the West they migrate south as far as New Mexico. Their main food sources are rabbits, hares, grouse and carrion, though they eat marmots, ground squirrels, moles, mice, skunks, weasels, badgers, herons, hawks, coots, ducks, magpies, fish and snakes. A breeding pair requires about 705 pounds of live weight food each year.

They hunt with cat-like surprise with one in five attacks successful.

Sight of a bald eagle on a perch

Bald eagles, with their white heads and tail feathers, can often be seen on a commanding perch along shores of oceans, rivers and lakes searching for fish. They also rely upon waterfowl and carrion for sustenance. As long as there is open water, these spear fisherman will swoop, snatch and return.

Sometimes bald eagles will plunge into water. If they become waterlogged, they will swim, using the butterfly stroke, ashore.

Bald eagles have huge treetop nests, 8 feet across and 12 feet high, weighing 3,968 pounds. Golden eagles prefer nesting on cliffs. Both species build their nests with sticks carefully woven into place with their bills.

Clutch sizes range from one to three eggs. Usually only one golden chick survives, as it kills its sibling(s). Eagle chicks add about 1 pound every four or five days, reaching full size after 10 weeks. Only 50 percent of bald eagles survive their first winter and that number is even lower for golden eagles.

Eagle populations markedly declined during the 20th century. They have been shot at, poisoned and electrocuted; yet they have proven adaptable and resilient.

Sensitive land planning and wild fish stock management is of paramount importance to the health of eagle populations. We have much to learn from this raptor. If we use poison, belch toxins and sully our fresh water, we kill the magnificent eagles. Eventually, that toxicity will kill humans, too.

Eagles are meant to rule the sky
The eagle is America's icon and as an apex-predator, it is an excellent indicator of the health of an ecosystem.
