Back then, the popular use of DDT pesticides after World War II had decimated the eagle population. In 1967, the Bald Eagle received protection under the predecessor to the federal Endangered Species Act. Then in 1972, the United States banned DDT.<\/p>\n<p>Thanks to legal protections (the Bald Eagle was a charter member of the eventual ESA signed into law in 1973), captive-breeding programs, and habitat protection around nests, the Bald Eagle population rebounded. From the 1960s through the early 2000s, the\u00a0USFWS\u00a0tabulated the growing numbers of eagles through surveys provided from the states. Then in 2009, two years after the Bald Eagle was delisted from the ESA, the agency conducted the first national eagle survey to monitor post-delisting population trends. The 2009 eagle count came from\u00a0aerial surveys, as\u00a0pilots from the\u00a0USFWS\u00a0Migratory Bird Program\u00a0flew\u00a0eagle-counting missions over high-density eagle-nesting areas to count numbers of occupied nests.<\/p>\n<div class=\"wp-block-image\"><figure class=\"alignright size-large\"><img decoding=\"async\" src=\"https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2021\/03\/BEagle-Nest-Viens-ML.jpg\" srcset=\"https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2021\/03\/BEagle-Nest-Viens-ML-720x477.jpg 720w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2021\/03\/BEagle-Nest-Viens-ML-768x509.jpg 768w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2021\/03\/BEagle-Nest-Viens-ML-480x318.jpg 480w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2021\/03\/BEagle-Nest-Viens-ML.jpg 1200w\" sizes=\"\" alt=\"Bald Eagles on a nest with two young in Maine.
