Eagles Across America

Half a century ago, the bald eagle was in danger of extinction. Habitat loss, illegal shooting and food source contamination (largely via the pesticide DDT) decimated the bald eagle population. Conservationists helped lead a remarkable recovery, aided by the government’s banning of DDT in 1972 and passage of the Endangered Species Act in 1973. The bald eagle was removed from the federal list of threatened and endangered species in 2007.

This photo essay touches on why the bald eagle inspires the awe and respect that it does.

“Bald eagles tend to evoke passion and emotion in people that few other wildlife species can match,” says Matt Stuber, the U.S. Fish and Wildlife Service’s Pacific Region eagle coordinator. “Maybe it’s their size. Maybe it’s because they are our national symbol. Or maybe it’s because many people grew up in a time when bald eagles were rare, which made them all the more special. Maybe it’s all of the above.”

Author E.F. Schumacher said: “Eagles come in all shapes and sizes, but you will recognize them chiefly by their attitudes."

“Many people think bald eagles are fish specialists, and they are great at catching fish. But eagles are actually generalists, which means they will eat pretty much anything that they can get their talons on,” says Stuber. “Some bald eagles catch muskrats, waterfowl, turtles, goslings, pheasants, gulls and rabbits. Bald eagles are also scavengers, and commonly feed on a wide variety of carcasses. Scavenging is particularly common in the winter months, when live prey is relatively scarce in some areas."

One thing about bald eagles that amazes Stuber is “how adaptable they have shown themselves to be to the presence of humans.” Decades ago, he says, biologists would have said ideal bald eagle nesting habitat was a river environment or marshy area with super-canopy [tall] trees far away from human activity. “And that still is true. But as populations increase over much of their North American range, bald eagles are building nests and raising young in increasingly developed places … even occasionally directly above peoples’ yards and homes."

Bald eagles still face many human-related threats. Among a few cited by Stuber, in no particular order, are:

Today, eagles are protected by at least three laws, the Bald and Golden Eagle Protection Act, the Migratory Bird Treaty Act and the Lacey Act.

Bald eagles’ breeding seasons vary with latitude. In Alaska and the northern tier of the lower 48 states, bald eagles lay eggs in early spring and raise young in late spring and summer. However, in the Southeast, bald eagles lay eggs in October or November, and young leave the nest in late January or February.

“As a kid from Wisconsin, I’ve always found this fascinating,” says Stuber. “The thought of eagles in Florida incubating eggs in the fall and raising young in the winter, as people in the upper Midwest celebrate the New Year underneath multiple feet of snow is pretty amazing to me."

Random facts: 1) Female bald eagles are larger than males. 2) A bald eagle’s eye is almost as large as a human’s, but its sharpness is at least four times that of a person with perfect vision. 3) Bald eagles can fly about 40 mph and soar to an altitude of 10,000 feet. 4) Immature bald eagles don’t develop their characteristic white head and tail until they are four or five years old. Before that, it is hard to distinguish them from golden eagles. 5) Bald eagle nests can reach 10 feet wide and weigh two tons. More bald eagle facts are available here and here and here.

January is National Bald Eagle Watch Month, and refuges can be great places to see eagles. Four refuges – Bear Valley in Oregon, Karl. E. Mundt in South Dakota and James River and Elizabeth Hartwell Mason Neck in Virginia – were established specifically for the benefit of bald eagles.

Tule Lake National Wildlife Refuge in California and Lower Klamath National Wildlife Refuge along the Oregon-California border are two of the best places on the West Coast to see bald eagles in winter. See story and video.

Upper Mississippi River National Wildlife and Fish Refuge in Minnesota, Wisconsin, Illinois and Iowa, Minnesota Valley National Wildlife Refuge in Minnesota, Seney National Wildlife Refuge in Michigan, Trempealeau National Wildlife Refuge in Wisconsin and Port Louisa National Wildlife Refuge in Iowa are among approximately 30 refuges that are home to bald eagles in the Midwest.

Reelfoot National Wildlife Refuge along the Tennessee-Kentucky border, Alligator River National Wildlife Refuge in North Carolina, Sam D. Hamilton Noxubee National Wildlife Refuge in northeastern Mississippi and Bayou Cocodrie National Wildlife Refuge in Louisiana are among approximately 30 refuges that are home to bald eagles in the Southeast.

Blackwater National Wildlife Refuge in Maryland, about 95 miles southeast of Washington, DC, is among roughly 30 refuges that are home to bald eagles in the Northeast. Others include Montezuma National Wildlife Refuge in New York, Edwin B. Forsythe National Wildlife Refuge in New Jersey and Moosehorn National Wildlife Refuge in Maine.

Alaska is home to more bald eagles than any other state. According to the most recent U.S. Fish and Wildlife Service estimate, there are roughly 72,000 bald eagles in the lower 48 states and roughly 70,000 in Alaska alone.
