Snowy Egret - Egretta thula

The Snowy Egret wades in shallow water hoping to flush out fish or other aquatic food. Sometimes these birds stir the water with their yellow feet, either to attract or to frighten nearby fish into moving.

Snowy Egrets also forage from the air. They might fly low over the water and dip their bill beneath the surface, dive from a perch, or catch flies in the air.

The dull yellow lores turn cherry red during mating season. During courtship, these birds display spectacular head, neck, and scapular plumes or aigrettes.
