Expansion:
There are 13 species of birds in the genus Egret, among which there are four types of birds: great egret, medium egret, white egret (little egret) and snowy egret, all of which have full body plumage. White, commonly known as egret.
The great egret is large in size and has neither crest nor breast feathers. The medium egret is medium in size and has no crest but breast feathers. The egret and snowy egret are small in size and have all the feathers on the crest and breast. The crown feathers and cape feathers produced by egrets during the breeding season can be used for decoration. They are commonly known as egret silk feathers and are often exported to Europe, America and other parts of the world.
Crying: It makes a croaking sound in the breeding nest, and is silent the rest of the time.
Distribution range: Africa, Europe, Asia and Oceania.
Distribution status: The named subspecies is a common resident bird and migratory bird, distributed in southern China, Taiwan and Hainan Island. Lost birds sometimes come to Beijing. Some birds spend the winter in tropical areas.
The breeding season of egrets is from May to July every year. They nest on islands near the coast and on rocks at overhanging rocks on the coast or between short tree branches. They like to build nests together in groups. Someone once found 14 nests on the top of a hanging rock of only about 20 square meters, and on the top of an adjacent hanging rock of only more than 10 square meters. There are 11 nests on the top of the rock, and the distance between each nest is only 14 to 76 centimeters.
In the past, there used to be mixed groups of yellow-billed egrets, egrets, cattle egrets, night herons and herons nesting in Taiwan. Its nest has a shallow saucer shape and a relatively simple structure, mainly composed of withered grass stems and grass leaves.
The nest is built on a dwarf tree, and the height from the ground is no more than 1 meter. Some nests are also built in the grass under a dwarf tree. Each clutch lays 2 to 4 eggs. The eggs are oval in shape and light blue in color. The incubation period is 24 to 26 days.
The feathers of egrets are of high value, and their feathers are mostly white. During the breeding season, they have long decorative nuptial feathers. Habits are broadly similar to those of other herons, but some species have courtship displays that include displays of their feathers.
