"The Great Blue Heron is in the middle of its food web, being a second-order consumer, or a carnivore. Predators of the Great Blue Heron include red-tailed hawks, black bears, bald eagles, crows, ravens, and raccoons. The Great Blue Heron feeds mainly on small fish two to eleven inches long, and it also eats a variety of other animals, including the following: insects, crayfish, snakes, salamanders, frogs, marsh birds, mice, mollusks, crustaceans, and ground squirrels. It is also a sneaky predator at red-winged blackbird nests, and it steals fish from gulls. Great Blue Herons also eat some plants to help them form pellets that they can cough up to expel things that the birds cannot digest." http://www.twingroves.district96.k12.il.us/wetlands/Herons/GreatBlueHeron/GBHeronFoodWeb.html
Most predators of GBHs go after the babies, as the formidable stabbing beak of a full-grown bird keeps all but the largest or most foolish predator at bay.
