Weeks-McLean Act Law and Legal Definition

The Weeks-McLean Act was the first U.S. law that regulated the shooting of migratory birds. Pursuant to the provisions of the Act, the Secretary of Agriculture was given the power to set hunting seasons nationwide. The Act prohibited the spring hunting and marketing of migratory birds. It also prohibited the importation of wild bird feathers for use in the women fashion world.

Although, the Act became effective on 4 March 1913, it was soon replaced by the Migratory Bird Treaty Act of 1918.
