Step 4
Watch the bird fly. It is hard to miss a great blue heron in flight because of its 6 foot wide wing span. They can fly as fast as 23 miles per hour. The great blue heron is commonly confused with the crane, but a heron's neck is crooked while flying and the crane keeps its neck straight.

Listen to the bird. The great blue heron makes a sound like "kraaank" that is loud and hoarse. Some say it sounds like squabbling and squawking.
