Asian Cattle Egret is a small heron of Asia and Australasia that follows cattle or tractors to catch insects they disturb. In the continental United States, the familiar cattle egret is the similar Western Cattle-Egret (Ardea ibis). Asian Cattle Egret is also called Eastern Cattle-Egret.
In breeding plumage, the eastern bird has buff-orange across most of the head and neck, while the western bird usually shows more white on the neck. Outside breeding plumage, photographs often cannot separate them reliably.
Why they get mixed upThey were long treated as one species and look very similar when mostly white.
