The once shrinking population of bald eagles has quadrupled over the past 12 years, according to a new survey conducted by the U.S. Fish and Wildlife Service. The study has found that there are over 316,000 bald eagles in the lower 48 states of the U.S., with over 70,000 breeding pairs.

According to the U.S. Fish and Wildlife Service, there were approximately 500 breeding pairs of bald eagles in the U.S. in the late 1960s. However, the story changed with the discovery that DDT, often found in insecticides, was affecting wildlife, effectively leading to its ban in 1972. In 1973, the federal government signed the Endangered Species Act, which led to the protections of various species, including the bald eagle.
Since then, the population has been growing gradually, and the bird was removed from the endangered species list in 2007. Following a recent survey, the U.S. Fish and Wildlife Service has discovered that the number of bald eagles has more than quadrupled since 2009 when they were last counted.
Speaking to the press, Interior Secretary Deb Haaland said that this turnaround is historic. “The bald eagle has always been considered a sacred species to American Indian people, and similarly it’s sacred to our nation as America’s national symbol,” Haaland said.
This success story proves that conservation measures work. Although the birds were hunted, killed and poisoned for years, the population has grown thanks to focused conservation efforts.
While the report might seem like a good indication for the future of wildlife in the U.S., the reality on the ground is quite different. A recent study by Cornell Lab of Ornithology has established that the overall population of birds in the U.S. has dropped by about one-third in the past 50 years. A different report by the National Audubon Society has established that about two-thirds of North American birds are at an increased risk of extinction, primarily because of climate change.
“By stabilizing carbon emissions and holding warming to 1.5 degrees Celsius above pre-industrial levels, nearly 150 species would no longer be vulnerable to extinction from climate change,” the report noted.
