Get a glimpse of elegance in the marshlands By James M. Hale
The Snowy Egret (Egretta thula) is a small, dainty, white heron that is a permanent resident in most of California, South America, Central America, the Atlantic Coast, and Gulf Coast. It is found widespread in the ponds, marshes, sloughs, and wet fields throughout Contra Costa County, particularly in winter, when post-breeding individuals disperse from their nesting colonies. Adults are about two feet long with a wingspan that may exceed forty inches. The Snowy Egret typically weighs less than one pound. The slim black bill and long black legs with bright golden yellow feet are diagnostic. The area of the upper bill, in front of the eyes, known as the culmen, is yellow. During the breeding season, the culmen turns red, as adult Snowy Egrets grow long, recurved nuptial plumes on their backs for courtship displays.
T h e s e b e a u t i f u l p l u m e s, called aigrettes, were in great demand by market hunters as decorations for women’s hats. The population of the species was reduced to dangerously low levels nearing extirpation. The first breeding evidence documented for California wasn’t provided until W. L. Dawson found a nest in Merced County in 1914. Fortunately, full protection in the United States by law, under the Migratory Bird Species Act, has allowed the Snowy Egret population to dramatically rebound. S n ow y E g re t s n e s t i n isolated colonies protected by dense vegetation. Salt marsh islands, swamps, and marshes are ideal nesting habitat. They often change location year after year. Such is the case in Contra Costa County where Snowy
Egrets nest sporadically. Ninetyfive nesting pairs occupied Brooks Island near Richmond in 1994. The first known nesting for Contra Costa County was at Browns Island north of Pittsburg where an estimated 100 pairs were nesting in kangaroo thorns in 1962. These sites have been abandoned and reoccupied over the years. Nesting season usually runs from April through July. After courtship, the male Snowy Egret selects the nest site with both sexes constructing the platform stick nest. Usually three to five pale blue-green eggs are laid. Both sexes incubate the eggs for twenty to twenty-four days. Nestlings fledge after thirty days. The average lifespan is about fifteen years in the wild. The Snowy Egrets diet includes fish, insects,
crustaceans, frogs, snakes, lizards, snails, worms, and rodents. They actively pursue and forage for their food. On occasion, they may ambush their prey by standing still and waiting. A peculiar method of See EGRET page 7
