Subspecies
Little Egret (Egretta garzetta) and Dimorphic Egret (Egretta dimorpha) (Sibley and Monroe 1990, 1993) have been lumped into Egretta garzetta following Kushlan and Hancock (2005) who also lump Western Reef Egret (Egretta gularis) with Egretta garzetta. The latter treatment is under review by the BirdLife Taxonomic Working Group.
