Yes, the bald eagle population is increasing and has been for decades. The most recent federal estimate, published in 2020, counted roughly 316,700 individual bald eagles in the lower 48 states, including 71,400 nesting pairs. That’s a staggering rebound from 1963, when the species hit an all-time low of just 417 known nesting pairs.
How Fast the Population Has Grown
The bald eagle’s recovery is one of the most dramatic wildlife comebacks in modern history. Between 1981 and 2005, the nesting population surged by about 700%, which works out to roughly 9% annual growth. That pace continued in the years that followed, ultimately leading to the species being removed from the Endangered Species Act in August 2007.
To put the scale in perspective: the population went from a few hundred breeding pairs to more than 71,000 in about six decades. Eagles now nest in every state in the lower 48, including many areas where they hadn’t been seen in generations. If you’ve noticed more bald eagles near rivers, lakes, or coastlines in recent years, you’re not imagining it.
What Drove the Recovery
The single biggest factor behind the eagle’s decline was DDT, a pesticide widely used from the 1940s through the early 1970s. DDT accumulated in fish, and eagles that ate contaminated fish laid eggs with shells so thin they cracked under the weight of an incubating parent. The U.S. banned DDT in 1972, and that ban, combined with Endangered Species Act protections and aggressive habitat conservation, gave the population room to rebuild.
Federal and state wildlife agencies also ran captive breeding and reintroduction programs, relocating young eagles into regions where local populations had been wiped out. Strict protections on nesting sites helped too, giving breeding pairs the undisturbed space they need. Eagles typically use the same nest year after year, adding material each season until some nests weigh over a ton.
Threats That Still Slow Growth
The population is growing, but not as fast as it could be. Lead poisoning is the most significant ongoing drag on bald eagle numbers. Eagles scavenge on carcasses and gut piles left by hunters using lead ammunition, and even small fragments can be lethal. A large-scale study by the U.S. Geological Survey found that lead exposure is reducing the bald eagle population growth rate by 3.8% annually. In practical terms, that means the population is still climbing, but lead is meaningfully holding it back from where it would otherwise be.
Avian influenza has also emerged as a newer concern. The highly pathogenic H5N1 strain that swept through North American bird populations beginning in early 2022 killed confirmed bald eagles in at least 24 states. By June 2022, 136 eagle deaths had been linked to the virus. Some of those were nesting adults, meaning entire breeding attempts failed along with the loss of the adult birds. The long-term population impact of H5N1 is still unclear, but the virus has not reversed the overall upward trend.
Other hazards include collisions with vehicles and wind turbines, electrocution from power lines, and habitat loss along waterways. None of these individually threatens the population at a national scale, but they add up, particularly in areas where eagle density is high and human infrastructure is expanding.
What the Numbers Mean Going Forward
With over 300,000 individuals and tens of thousands of active nests, the bald eagle is no longer a species in crisis. The population is large enough and widespread enough that localized threats are unlikely to reverse the overall trend. The species is considered secure under both federal and most state wildlife management frameworks, though it still receives legal protection under the Bald and Golden Eagle Protection Act, which prohibits killing, capturing, or disturbing eagles or their nests without a permit.
The growth rate has naturally slowed as eagle numbers have climbed, which is expected. As more territories fill up, young eagles face more competition for prime nesting sites and food sources. In some regions, the population may be approaching what the habitat can support. But across the country as a whole, the trajectory remains upward, and bald eagles are now a common sight in places where they were absent for most of the 20th century.
