In 1963, when the species was at its lowest ebb, there were only an estimated 417 breeding pairs of Bald Eagles in the lower 48 states. The 2016 data showed a 5 percent annual increase in Bald Eagle numbers across the continent. Once DDT was banned and the species was fully protected under the fledgling Endangered Species Act, however, eagle numbers began to rebound, gradually at first and then with increasing vigor. Once a common sight in much of the continent, the bald eagle was severely affected in the mid-20th century by a variety of factors, among them the thinning of egg shells attributed to use of the pesticide DDT. In 2007, the bald eagle population in the United States reached a level that brought it down from the \"endangered\" list to the \"threatened\" list, so scientists are hopeful for the growth of the species.

Their habitat includes estuaries, large lakes, reservoirs, rivers, and some seacoasts. Millsap says a second round of surveys is occurring right now. Bald eagles, like many birds of prey, were especially affected by DDT due to biomagnification. Golden Eagles avoid nesting near urban habitat and do not generally nest in densely forested habitat. Taking the Bald Eagle off the endangered species list didn't mean an end to federal regulations concerning the management of the species. (In regulatory terms, this is known as “take” of a species.) Other pesticides whose effects aren't yet well understood have entered the market, such as brodifacoum, one of a broader class of chemicals known as second-generation anticoagulant rodenticides, or SGARs. When it does, it may be due to the species naturally hitting its carrying capacity — a term used in ecology to define the maximum population size a region's resources can sustainably support. Habitat protection afforded by the Endangered Species Act, the federal government’s banning of DDT, and conservation actions taken by the American public have helped Bald Eagles make a remarkable recovery. These carcasses often contain fragments of lead ammunition, which eagles and other scavengers gulp down along with the meat.

Female eagles laid eggs that were too brittle to withstand th… The young eagles are flying within three months and are on their own about a month later. So says Bryan Watts, Director of Virginia's Center for Conservation Biology and a professor at the College of William and Mary, who studies Bald Eagles of the Chesapeake Bay region. Although they hunt fish and other prey, Bald Eagles are also frequent scavengers, and a gut pile left behind by a game hunter represents a tempting meal. DDT, a synthetic pesticide, was … Photo by Mike Parr. Male eagles are smaller, weighing as much as 10 pounds and have a wingspan of 6 feet. The resulting efforts to restore the species went beyond the simple elimination of DDT use: eagles' nests and habitat were now strictly protected from human disturbance of all sorts. Although there were only five known Bald Eagle deaths from brodifacoum poisoning between 1982 and 2013, compared to 484 from lead, it's beginning to show up at chronic low levels in even the most isolated Bald Eagle populations, which wildlife managers are at a loss to explain. But what did “delisting” truly mean for Bald Eagles? No one wants to see an eagle killed by human activity. “So when Bald Eagles were delisted, we defined the preservation of the species as maintaining stable breeding populations.

The eagle population hit rock bottom in 1963, when only 417 mating pairs could be documented in the 48 states and the survival of the species was in question. Individuals will occasionally nest near semi-urban areas where housing density is low and in farmland habitat; however Golden Eagles have been noted to be sensitive to some forms of human presence. However, as populations have grown, more and more individuals have moved into upland areas where the hunting of deer and other large animals is common. That's a conservative management objective — not only are we not going to let them go extinct, we're going to try and maintain populations at at least the size they are now.”, Interior Secretary Dick Kempthorne announces the Bald Eagle's delisting at a ceremony on the steps of the Jefferson Memorial in Washington, D.C., in 2007.
