The U.S. Fish and Wildlife Service is the primary federal agency charged with "protecting and enhancing the populations and habitat of more than 800 species of birds that spend all or part of their lives in the United States." As such, this site serves as a good clearinghouse for information on the various programs administered by the Service, such as the Waterfowl Population Surveys which have been conducted over the past half-century. The site is divided into four primary sections and visitors will want to take an extended look at the Education and Research area. Here individuals can learn about the various surveys that are conducted annually; and, more importantly, read through some of their helpful educational materials, such as the informative Birdscapes Magazine and the fact sheets on migratory birds. Those persons interested in the broader legal and policy context of their work will want to look through the Laws, Regulations, and Policy area, which contains policy statements, information on hunting regulations, and the text of such legislative actions as the Migratory Bird Treaty Act.
