Egrets are wading birds closely related to herons, with long legs, necks, and bills, as well as short tails. They are carnivorous and are typically found near bodies of water hunting for fish, frogs, lizards, or mice. During the breeding season, male egrets grow long, lacy feathers called aigrettes, which they use as part of their mating display. The Snowy Egret's face turns red during this time, while the Great Egret's face turns bright green. But do egrets have facial muscles?

What You'll Learn
Egrets' faces turn green during mating season
The great egret is a graceful and elegant bird, native only to Africa. It is the tallest of the egret species, with black legs and an orangish-yellow bill. During the breeding season, which lasts from April to September, the great egret undergoes a transformation. The male great egret, already distinguished by its pristine white plumage, develops a bright green patch of skin on its face between the eyes and the bill. This patch of skin is not a pigment but a structural colour, formed by light refraction. The feather surface has structures that form tight slits, around the size of the wavelength of light that is going to be displayed. When white light bounces into the slits, most colours bounce around and get absorbed, but the desired colour is reflected back out.
The great egret's mating behaviour is a spectacle of elaborate displays, territorial defence, and intricate rituals. Male great egrets showcase their enhanced breeding plumage and engage in specific behaviours to entice a mate. This involves a combination of visual displays, vocalisations, and carefully selected nest locations. The entire process is designed to signal vigour and health, ensuring the selection of the best possible partner for reproduction. The great egret is monogamous during a single breeding season, meaning they will raise a clutch with the same partner. While they do not mate for life, great egrets will often return to the same breeding colonies and possibly even pair with the same mate in subsequent years.
Great egrets build nests in trees, bushes, or thickets, usually in colonies called rookeries, and they prefer the higher nesting sites. The male builds or renovates a large platform nest of sticks lined with twigs and grasses. The female then lays several light blue eggs that are incubated for about 25 days. After hatching, the chicks leave the nest in about 23 days and move about on nearby branches before fledging. Young chicks are aggressive towards one another in the nest, and stronger siblings often push their weaker kin out of the nest.
Great egrets are migratory birds, typically seen locally from spring through fall. The birds that come to the northern United States for the summer spend their winters in Central and South America or sometimes as far away as the West Indies. In the late 1800s, their population was decimated nearly to the point of extinction due to hunting for their feathers. Today, organisations like Google and the City of Mountain View work to protect the birds and educate the public about them.

They are wading birds, closely related to herons
Egrets are wading birds, closely related to herons. They are long-legged, graceful, and elegant, with white or buff plumage. They are typically found near bodies of water, such as lakes, bays, creeks, and wetlands, where they hunt for fish, frogs, and other small aquatic animals. They are also known to hunt in fields and hills, and their diet includes lizards and mice. Egrets are not a biologically distinct group from herons, and they share the same build. They are both members of the bird family Ardeidae and are placed in the same genus, with some variation. The genus Ardea includes the Great Blue Heron and the Great Egret, while the genus Egretta includes the Snowy Egret, Little Blue Heron, and Tricolored Heron. The distinction between a heron and an egret is vague and depends more on appearance than biology.
The breeding season for egrets lasts from April to September, during which male egrets build or renovate large platform nests of sticks lined with twigs and grasses. The female then lays several light-blue eggs, which are incubated for about 25 days. After hatching, the chicks remain in the nest for about 23 days before moving to nearby branches. Young chicks are aggressive towards one another, and the stronger siblings often push their weaker kin out of the nest. Egrets are colonial nesters, typically placing their nests high in trees or shrubs, often on isolated islands to protect themselves from mammalian predators.
During the breeding season, egrets develop long, wispy plumes on their backs, which are used in courtship displays. These plumes, called aigrettes, are the origin of the name "egret", derived from the French word "aigrette" meaning "silver heron" or "brush". The pursuit of these feathers by hatmakers in the 19th and early 20th centuries led to the endangerment of some egret species. The great egret, for example, was almost driven to extinction, with populations decimated by hunting.
Egrets and herons are both carnivorous and share similar hunting methods. They use their long necks and dagger-shaped beaks to spear their prey. They typically stand still in shallow water, waiting for unsuspecting prey to pass by, and then strike with startling speed. Egrets and herons also share similar nesting habits, as they both nest in colonies, often alongside each other in rookeries.

Egrets are carnivorous
The egret's diet is not limited to fish, as they are opportunistic foragers and will eat almost anything that fits in their mouths. They feed on crustaceans, amphibians, insects, frogs, lizards, snakes, small birds, and even small mammals like rodents and squirrels. The little egret, for instance, primarily feeds on small fish like minnows and gobies, but will also eat frogs, tadpoles, shrimps, crabs, molluscs, and aquatic insects. If other food sources are scarce, they will also prey on small reptiles and mammals.
Different egret species have different dietary preferences depending on their habitat. For example, the great egret's diet consists of fish, crustaceans, amphibians, and small mammals, while the snowy egret's diet includes small fish, crustaceans, and aquatic insects. The cattle egret, true to its name, often lives near livestock and hunts by following cows and other large farm animals to eat the bugs that are stirred up by the cow's movement.
Egrets are known for their elegant, graceful appearance, with tall, slender bodies, long legs, and white plumage. They are migratory birds, typically seen from spring through fall, and their breeding season lasts from April to September. During this time, they develop long, wispy plumes and become territorial and aggressive in defence of their space and food sources.

They are colonial nesters
Egrets are wading birds, which means they are typically found near bodies of water, such as lakes, ponds, marshes, estuaries, and rivers. They are also known to hunt in fields and hills. Egrets are carnivores and will eat fish, frogs, lizards, and even mice.
During the breeding season, egrets live in colonies in trees or shrubs, often alongside other waterbird species. The male chooses the display area, where the nest is later constructed. These nests are usually located 10-40 feet above the ground or water, though some nests can be found very low in a thicket or marsh, and others can be up to 90 feet high in tall trees. The male builds the nest platform from long sticks and twigs, and both sexes may collaborate to complete the nest, though sometimes the male finishes it himself. The nest is lined with pliable plant material that dries to form a cup structure. The female then lays several light blue eggs, which are incubated by both parents for about 25 days. After hatching, the chicks remain in the nest for about 23 days before moving to nearby branches, and they are able to fly at 6-7 weeks.
Great egrets are usually solitary nesters, while snowy egrets are colonial nesters that breed in large aggregations. Snowy egrets build their nests in close proximity to each other, sometimes with hundreds of pairs in a single colony. Great egrets, on the other hand, spread out from each other even when nesting in the same general area.
Egret populations were severely impacted by plume hunting in the late 1800s and early 1900s, with over 95% of Great Egrets in North America killed for their feathers. However, populations began to recover after hunting was banned, and egrets became a symbol of conservation efforts.

Egrets were hunted for their plumes in the 1800s
Egrets are a group of tall, stately, and graceful birds, commonly found near bodies of water. They are carnivores, and their diet includes fish, frogs, lizards, and mice. They are migratory birds, and their breeding season lasts from April to September. During this time, they develop long, lacy feathers, or "aigrettes," that are used in their mating displays.
Unfortunately, in the 1800s, these very aigrettes, or plumes, became highly sought-after for use in fashion, particularly in women's hats. This fashion craze, which began in the 1870s, led to the extensive hunting of egrets for their plumes. Hunters would shoot the adult birds and leave the chicks to starve or be preyed upon by other animals. The egret population was decimated to the point of near extinction. In 1886, it was estimated that 5 million birds were being killed annually for the millinery trade, with egrets being a primary target.
The hunting of egrets for their plumes was a lucrative business, with the plumes selling for a high price—$32 an ounce in 1915, which was approximately the price of gold at the time. This financial incentive drove hunters to lie in wait at the nests of egrets during the nesting season, killing the adults and leaving the chicks vulnerable. The hunting was so intense that by the late 1880s, there were no longer any large numbers of plume birds within reach of Florida's most settled cities.
However, thanks to the efforts of early conservationists and organizations like the National Audubon Society, the slaughter of egrets for their plumes was eventually stopped, and their populations were able to recover. The passage of laws such as the Migratory Bird Act and the establishment of protected areas, like Pelican Island, played a crucial role in safeguarding these graceful birds.
