The Migratory Bird Treaty Act of 1918 (MBTA), codified at , is a United States federal law, first enacted in 1916 in order to implement the convention for the protection of migratory birds between the United States and Great Britain (acting on behalf of Canada). The statute makes it unlawful without a waiver to pursue, hunt, take, capture, kill or sell birds listed therein ("migratory birds"). The statute does not discriminate between live or dead birds and also grants full protection to any bird parts including feathers, eggs and nests. Over 800 species are currently on the list. The U.S. Fish and Wildlife Service issues permits for otherwise prohibited activities under the act. These include permits for taxidermy, falconry, propagation, scientific and educational use, and depredation, an example of the latter being the killing of geese near an airport, where they pose a danger to aircraft.
