At times it is easy to be mistaken in the field. Locally Intermediate Egrets (Ardea intermedia intermedia) are not as common as Great Egrets (Casmerodius albus modestus). When I saw these 4 birds I thought they were Great Egrets but a closer look showed them to be Intermediate Egrets.

Posting a composite comparison of the birds I saw on this day with Great Egrets. Good signs are the dagger-mark that does not go behind the eye and the tip of the bill is black in Intermediate Egrets. The neck curvature in Great Egrets and shorter bills in Intermediate Egrets are other good pointers.
