Mexico's problem with bird flu has forced the U.S. Department of Agriculture to issue a declaration that hunters may not bring any dead birds back into the U.S. after hunting in Mexico. If you shoot it, you better eat it there or give it away. Huey Lyons of Lyons & O'Haver Taxidermy said a veterinarian from the U.S. Department of Agriculture visited his La Mesa shop recently and told him he can't take any birds in that were shot in Mexico. It applies to doves, quail, pheasants, ducks and geese. A spokesman for the U.S. Department of Agriculture confirmed the new regulation.
