Great Blue Heron Facts

Great Blue Herons are on every birders bucket list. These large waterfowl are a strikingly beautiful bird. In flight they have methodically slow wing beats and keep their long necks bent into the famous "S" shape, which improves aerodynamics and allows for quick strikes on unsuspecting prey. When not in flight, they often stand perfectly still, until prey wanders by and their statue like pose bursts into life. These giant birds can have a six and a half foot wingspan yet only weigh five and half pounds. That light weight allows them to stand atop of floating vegetation such as kelp and wait for dinner to swim by. Great Blue Herons have excellent night vision, which allows them to hunt both during daylight and in the cover of darkness. The long frayed feathers on their chest continually grow. Herons use them to clean themselves of fish slim and other waste.
