The Great Egret (Ardea alba) is a bird in the heron family, Ardeidae[5]. It is ranked Secure worldwide by NatureServe and is not listed under the US Endangered Species Act[2][1].
Conservation status
NatureServe ranks the Great Egret G5, which means Secure worldwide[2]. In the United States it is ranked Secure for both breeding and nonbreeding birds[6]. The IUCN Red List category recorded by NatureServe is Least concern[7]. The bird is not listed as endangered or threatened under the US Endangered Species Act[1]. It is on the federal list of migratory birds protected under the Migratory Bird Treaty Act[8].

Where Great Egret lives
NatureServe lists the Great Egret as native in 46 US states and territories, including the District of Columbia[3]. These include Florida, California, Texas, New York and Minnesota, along with many other states from coast to coast[3]. NatureServe gives the Great Egret different conservation ranks in different states[10]. GBIF observation records are highest in Florida, California, Texas, New York and New Jersey, but those counts follow where people look and report[11].

Habitat
The Great Egret lives in wet places[12]. NatureServe records herbaceous wetland, scrub-shrub wetland, forested wetland, riparian areas, shallow water, bays, lagoons and tidal flats[12]. It also uses fields and meadows[13]. It nests mostly in tall trees, often alongside other colonial water birds, and colonies are reused from one year to the next[13].

Size, diet and lifespan
The Great Egret eats fish, frogs and other amphibians, snakes, snails, crabs and their kin, insects and small mammals[14]. It is recorded as a carnivore, a fish eater and an eater of invertebrates[15]. NatureServe records a typical length of 99 cm (39 in)[16]. A typical adult weighs 935 g[17]. A clutch is usually 3 to 4 eggs in the north and 2 to 3 in the south, and both parents incubate for 23 to 25 days[18]. The young fly at about 6 weeks[18]. The oldest known banded bird was at least 22 years 10 months old[4].

When to look for it
NatureServe describes the Great Egret as active in daylight and also around dawn and dusk, which is what crepuscular means[24]. Birds arrive at their night roost at sunset or dark and leave at first light[25]. Birds in the north migrate, and they spread out widely after breeding before heading south[26]. Some populations do not migrate, and others move only short distances[23]. GBIF records in the United States peak in April, May and September, which reflects when people look and report[27].
