It is generally legal to poison pigeons in the United States, but there are restrictions on the use of bird poison, and local counties may have ordinances against certain hunting methods. As of 2015, pigeons are among the few wild birds exempt from federal and state hunting laws.
As of 2015, the Migratory Bird Treaty Act makes it illegal to kill wild birds without a permit; pigeons, English sparrows and starlings are the three exceptions. This makes it generally legal to hunt and kill pigeons. While local laws cannot outright ban killing pigeons, they can restrict the ways in which they can be killed. In some counties, using poison to kill pigeons may be illegal, even though other methods, like shooting, are allowed. In addition, certain toxic substances used to kill pigeons are restricted on the federal level. For example, the bird poison DRC-1339 can only be used under supervision by the USDA-APHIS-Wildlife Services.
