Subspecies
Casmerodius albus (Sibley and Monroe 1990, 1993) is retained as a cross-regional species contra Christidis and Boles (2008) who move Casmerodius albus into the genus Ardea and split it into two cross-regional species Ardea alba and Ardea modesta (note gender agreement of specific name for alba).
The following 4 subspecies are recognised:
alba (Linnaeus, 1758) - Central Europe to central Asia, south to Iran. Winters northern and central Africa and Persian Gulf to southern China and southern Korea.
modesta Gray, JE, 1831 - India, south-eastern Asia, Japan and Korea south through Indonesia to Australia and New Zealand. Considered by some authors to be a distinct species, Eastern Great Egret (Ardea modestus).
melanorhynchos (Wagler, 1827) - Africa south of Sahara, Madagascar.
egretta Gmelin, JF, 1789 - Northern, central and southern America, from northern USA to central Argentina.
