Green herons are expert bait fishers, known to entice their prey with bread, popcorn, seeds, flowers, live insects, spiders, feathers, even pellets of fish food. Dung is the decoy of choice for the burrowing owl. The owls scatter clumps of animal feces near the mouth of their nest chambers and wait motionless like muggers for unsuspecting dung beetles to scuttle toward their trap.
