Chirp Caliente wild bird food has been carefully crafted to keep your bird feeder filled with birds, not squirrels. Popular grains, seeds, and nuts have been seasoned with spicy hot pepper, because birds are not affected by spicy food, but squirrels hate it. With no pesky squirrels to steal their treats, your backyard birds can enjoy a feast of high-energy sunflower, safflower, peanuts, and more.
