Great Blue Heron

"The tall, long-legged great blue heron is the most common and largest of North American herons.

Great blue herons are waders, typically seen along coastlines, in marshes, or near the shores of ponds or streams. They are expert fishers. Herons snare their aquatic prey by walking slowly, or standing still for long periods of time and waiting for fish to come within range of their long necks and blade-like bills. The deathblow is delivered with a quick thrust of the sharp bill, and the prey is swallowed whole. Great blue herons have been known to choke to death by attempting to swallow fish too large for their long, S-shaped necks. Though they are best known as fishers, mice constitute a large part of their diet, and they also eat insects and other small creatures.

Great blue herons' size (3.2 to 4.5 feet/1 to 1.4 meters) and wide wingspan (5.5 to 6.6 feet/1.7 to 2 meters) make them a joy to see in flight. They can cruise at some 20 to 30 miles (32 to 48 kilometers) an hour."
