These photos show an oversized Great Egret with gray neck markings, unusually long legs, and feathering that has the frazzled look of a Great Blue Heron on the back and on the neck. This may not be a hybrid, but it is definitely an anomaly. It helps that it posed so close to the "regular" Great Egret. --- Photos taken on Duxbury Beach, MA, just north of the Powder Point Bridge on August 4, 2009.
