Great Egret (Ardea alba)

  The Great Egret is a large bird with all-white plumage that can reach one meter in height and weigh up to 950 grams (2.1 lb)  It is thus only slightly smaller than the Great Blue Heron.  The Great Egret can be distinguished from other white egrets by its yellow bill and black legs and feet, though the bill may become darker and the lower legs lighter in the breeding season. In breeding plumage, delicate ornamental feathers are borne on the back. Males and females are identical in appearance; juveniles look like non-breeding adults.

There were plenty of Great Egrets at the river yesterday, along with several Great Blue Herons and Cormorants.  This image is my favorite of the day.
