Federal law protects all other birds.
This is known as habitat modification. That is why bird removal schemes, such as trapping or poisoning, are temporary, at best. Habitat modification solves the problem once and for all permanently, which means they don t get to come back over and over again, forever, to kill for profit, at your risk and expense. Harvard University and others have proven that pigeons are as smart as whales, monkeys, or most any other animal on the planet and, in some ways, are even smarter than humans. That goes for other birds, as well.
