Great Egret

The anatomical difference between herons, egrets, and bitterns is pretty negligible. Egrets tend to be whiter and have more plumage on their head and neck, while herons tend to be a little bit bulkier. The Great Egret is the largest of the egret group, reaching heights up to 40 inches. Its dagger-like bill is entirely yellow, as is its eye, while the legs and feet are a uniform black. They are locally common throughout the U.S., though they tend to avoid colder parts of the country.
