Bald Eagle Spotting: Top Spots

//

Forty years ago, the Endangered Species Act was signed into law by President Richard Nixon. The act’s authors sought to protect animals, plants and other wildlife from extinction caused by “economic growth and development untempered by adequate concern and conservation,” in the words of the Act.

One symbol of the United States, the bald eagle, provides an example of how a change to the economy saved an icon of North America.

DDT, or dichloro-diphenyl-trichloroethane, weakened eagle and other bird egg shells so much that the eggs would collapse under the mother. The chemical was introduced in the 1940s and already had decimated bird populations by the early 1960s.

In 1972, the U.S. Environmental Protection Agency banned the pesticide. The removal of DDT from the market allowed eagle eggs to regain their strength, and the raptors began a recovery.

Bald eagles soared off of the Endangered Species List in 2007. Although off the list, the birds are still protected by the Bald and Golden Eagle Protection Act, Migratory Bird Treaty Act and the Lacey Act, according to the U.S. Fish and Wildlife Service.

An eagle-watching trip could be a thrilling way to celebrate the 40th anniversary of the Endangered Species Act and the success of bald eagles.

From coast to coast, National Wildlife Refuges offer winter-long opportunities to observe the raptors, along with special events.

The USFWS presents a cross-country list of these eagle adventures in Maryland, Virginia, Illinois, Tennessee, Missouri, Oklahoma, Utah, California, Oregon and Washington. Here are a few highlights:

Maryland: Blackwater National Wildlife Refuge Eagle Festival March 15, 2014, from 9 a.m. to 4 p.m. The festival is a free way to see more than 200 eagles overwintering in the refuge, the largest population on the East Coast, north of Florida.

Illinois: Crab Orchard National Wildlife Refuge Eagle Watch Jan. 18-19, 25-26 at  8 a.m., 11 a.m. and 2 p.m. Reservations are required for this guided van trip to see eagle nests.
