Race coromandus sometimes treated as a full species, with some authors#R mentioning different morphometrics, breeding plumage and calls; another#R, however, indicated no difference in calls and that morphometric data yield only minor differences (effect size for longer tarsus 1.49, score 1; for shorter tail −0.94, score 1) (2), leaving the puffy, bright golden-orange head, neck and breast when breeding vs white on these parts except peachy-buffy crest and central breast plumes (3); thus, a total score of 5 retains this form at present as a well-marked subspecies, although further study may yield other points of divergence. Validity of race seychellarum has been questioned; only one specimen in breeding plumage known from collections. Three subspecies recognized.

Subspecies and Distribution
  • B. i. ibis (Linnaeus, 1758) – Western Cattle Egret – SW Europe to Caspian Sea, also Africa and Madagascar and Comoros; naturally expanded range (mainly during 20th century) to North, Central & South America, now breeding from S Canada to Argentina and Chile. Partially migratory in most of range; birds of North America winter S of 32° N.
  • B. i. seychellarum (Salomonsen, 1934) – Seychelles.
  • B. i. coromandus (Boddaert, 1783) – Eastern Cattle Egret – S & E Asia from Pakistan E to Japan; has expanded range to Australia and New Zealand. Partially migratory.
