What 1918 federal law was a joint resolution with Canada for migratory bird protection?

The Migratory Bird Treaty Act is the correct answer as it was established in 1918 to implement a treaty between the United States and Canada for the protection of migratory birds. This law made it illegal to hunt, capture, or kill migratory birds without a permit, addressing conservation concerns at a time when many species were declining due to overhunting and habitat loss. The Act serves as a cornerstone for wildlife protection in North America and reflects the cooperative effort between the two nations to safeguard migratory bird populations.

The other options do not pertain specifically to the treaty with Canada for migratory birds. The Endangered Species Act, for example, focuses on the conservation of species that are threatened or endangered but was enacted later, in 1973. The Lacey Act, which addresses the illegal trafficking of wildlife, was first passed in 1900 and does not specifically target migratory birds. The Limited Hunting Act is not a recognized piece of federal legislation focused on migratory birds and does not pertain to the joint resolution with Canada. Thus, the Migratory Bird Treaty Act stands out as the legislative measure aimed specifically at protecting migratory species through international cooperation.
