Mainly seen as singles or in small groups, standing quietly in or at the edge of water, less often hunting in fields. Plumage mostly gray overall, with paler neck; adult has white crown, black eyebrows, and black shoulder patch. Like other herons and egrets, flies with neck pulled in to form a bulge.
