Among the most elegant of the herons, the slender Snowy Egret sets off immaculate white plumage with black legs and brilliant yellow feet. Those feet seem to play a role in stirring up or herding small aquatic animals as the egret forages. Breeding Snowy Egrets grow filmy, curving plumes that once fetched astronomical prices in the fashion industry, endangering the species. Early conservationists rallied to protect egrets by the early twentieth century, and this species is once again a common sight in shallow coastal wetlands.
Adult Snowy Egrets have greenish-yellow feet for most of the year, but at the height of the breeding season their feet take on a much richer, orange-yellow hue. The bare skin on their face also changes color, from yellow to reddish.
