This Great Egret was on a mission, stalking something to eat in the shallow bayou water. The egret’s neck and body show reflected patterns from the water as it surveys the area. The surface of the water is covered by a noxious plant, the Giant Salvinia, an invasive species from Brazil discovered in the lake less than 15 years ago. It can double its biomass in days and threatens the health of the ecosystem in which it thrives so potentially this Great Egret could be adversely affected by it. There are currently modestly effective efforts underway to control the weed.
