The National Audubon Society launched in 1905, on the heels of American conservationism and a growing movement to protect birds. As with many efforts to conserve nature, women led the way: The first Audubon Society was organized by two Boston environmentalists, Harriet Hemenway and Minna B. Hall, in response to the widespread slaughter of waterbirds, the gorgeous feathers of which were used to make women’s hats. The pair’s efforts in Massachusetts soon helped inspire similar organizations across the country.
By the time the National Audubon Society incorporated in New York State, local members had already established key bird conservation efforts across the country, including the Christmas Bird Count, where volunteers take stock of early winter bird populations, and the United States’ first National Wildlife Refuge, Pelican Island in Florida.
In the decades that followed, the organization was on the front lines of the conservation movement, influencing policymakers to pass key legislation. Notable conservation laws in which Audubon helped pass include the Audubon Plumage Law in 1910 that protected wading birds from the depredations of the plume industry, the 1918 Migratory Bird Treaty Act—still one of the strongest bird-protection laws in the world today—that made it illegal to kill any non-game bird in the U.S., the Endangered Species Act in 1973, and the mammoth climate-change-focused Inflation Reduction Act in 2022. Audubon has also recently launched Conserva Aves in multiple countries in Latin America, a partnership that will protect 2 million hectares across nine countries. Meanwhile, Audubon also built nature centers and sanctuaries across the country; and helped to increase populations of many imperiled bird species, including Bald Eagles, Piping Plovers, California Condors, Least Terns, Great Egrets, and many more. Audubon’s work continues today across the hemisphere in the form of scientific research, policymaking, education, community engagement, and the conservation and management of 300 million acres of bird habitat.
