Why is the color of the egret white, and why is it not the protective color of the surrounding envir

The egrets are white in color because this is their natural protective color.

The egret is a medium-sized wading bird, with a body length of 52-68 cm, its neck is relatively long, its beak and feet are black, its body is slender, its whole body is white, it is very elegant, and the summer feather has two narrow and soft spear-like feathers on the occipital part, which looks like two long braids behind the head, which is very distinctive.

Egrets inhabit coastal islands, coasts, bays, estuaries, and rivers, lakes, ponds, streams, paddy fields, and marshes near their coasts. It can be seen in small groups alone, in pairs, or in groups, and occasionally in large groups of dozens together. During the day, they often fly to the streams, rivers, salt pans and rice fields near the coast to move and feed, and prey on small fish, amphibians, reptiles, mammals and crustaceans in shallow water.

Usually walking along rivers, salt pans, or paddy fields, it pecks while walking, and its long beak, neck, and legs are very convenient for preying on aquatic animals. When hunting, it gently wades and walks forward, its eyes constantly looking at the small animals moving in the water, and then suddenly pecks into the water with its long beak to accurately peck the food into its mouth. Sometimes, they often stand at the water's edge, waiting for an opportunity to prey on passing fish.

The egret has long ornamental wedding feathers during the breeding season, and some species have courtship performances, such as showing off their feathers. The breeding period is from May to July every year, and they like to nest together in groups, and the shape of the nest is shallow saucer, and the structure is relatively simple, mainly composed of withered grass stems and grass leaves. Nests are built on low trees, and the highest height from the ground is no more than 1 meter, and there are also nests among the grass under low trees.

Each clutch lays 2-4 eggs, which are oval in shape and light blue in color. The incubation period is 24-26 days.

Why is the color of the egret white, and why is it not the protective color of the surrounding environment?

The plumage color of egrets is normal, and white is just one of their protective colors. "The egret is a social bird, likes to assemble, loves to communicate, usually there are seven or eight egrets in a small group, and hundreds of them will often appear. "Because it is a group activity, white is easy to identify for them; Unlike the markings of beasts, when the egrets are in a flock, they take off together, and suddenly they are white, which can also play a role in disrupting the enemy's line of sight, making it difficult for eagles, falcons and other birds of prey to catch them.

The laws of survival in nature have always been cruel, only the fittest can survive, and the habits of the egret confirm this. They are particularly smart, in the course of patrol in previous years, the rangers have seen farmers use tractors to turn over the ground, the bold egrets stand near the tractor, and when the machine passes, they follow closely behind, picking up small insects that turn out of the soil, which can be called "leaks" masters.

Not only that, but they also have a talent for "cutting off beards". In the Juma River in Fangshan, where black storks are found, egrets are generally found, and they live in symbiosis and forage together. It's just that the black stork is very diligent in foraging, and will keep paddling the water surface in the tidal flats to look for small fish and shrimp, and the egret follows aside, waiting for the opportunity to grab food.

Despite their poor "reputation", egrets do have a strong ability to survive, unlike storks and cranes, and are not picky about water quality. All in all, a very interesting bird.
