Great Egrets in full breeding plumage sport long plumes called aigrettes that create lacy umbrellas when they perform their courtship rituals. Their yellow beaks become brighter yellow and the top mandible turns almost black. But most amazing is that their lores, the area between their eyes, turns from a dull yellow to a bright neon lime green. As I watched this Great Egret flying over the Wakodahatchee Wetlands in Florida last week, aigrettes streaming out behind, I noticed that the yellow of the beak and the green of the lores matched perfectly with the background foliage behind him. You gotta love nature.
