Great Egret: York County, Maine, USA — I always think that the wing of the Great Egret, or an egret of some kind, must have been the inspiration for angel wing paintings, and I always hope to catch a Great Egret preening. As it happens, they preen often and often extend their wings to get at the underside. The lighting here is dramatic. OM Systems OM1 with ED 100-400mm zoom at 800mm equivalent. Program mode with my custom birds and wildlife modifications. ISO 200 @ f6.3 @ 1/640th. -0.3EV.
