The great blue heron is the largest and most common of the North American herons. It is often seen standing at the edge of a tidal pond watching for small fish, its favorite prey. It also feeds on small mammals, reptiles, and occasionally, birds. This heron gets its name from its bluish-grey feathers and regal size. It has a huge wingspan of nearly 6 feet. When in flight, its neck folds into an S-shape, and you may hear it makes its call - a hoarse, gutteral squawk.
During the mating season, two feathers on the bird's head become long and thread-like. The great blue heron's eggs are generally light blue in color.
