Great Blue Herons appear blue-gray from a distance, with a wide black stripe over the eye. A pure white subspecies occurs in coastal southern Florida.
The white morph of the Great Blue Heron, formerly known as the "Great White Heron," is found nearly exclusively in shallow marine waters along the coast of very southern Florida, the Yucatan Peninsula, and in the Caribbean. The white morph of the Great Blue Heron distinguishes itselves from the Great Egret by its larger size, dusky pale to grayish yellow legs (instead of black) and its longer neck.
