Great Egret

The elegant Great Egret is a dazzling sight in many a North American wetland. Slightly smaller and more svelte than a Great Blue Heron, these are still large birds with impressive wingspans. They hunt in classic heron fashion, standing immobile or wading through wetlands to capture fish with a deadly jab of their yellow bill. Great Egrets were hunted nearly to extinction for their plumes in the late nineteenth century, sparking conservation movements and some of the first laws to protect birds.
