It is a bird of the genus passerine magpie. * * * There are 10 subspecies. The body length is 40-50 cm, and the male and female feathers are similar in color. The head, neck, back and tail are all black, showing purple, green, blue and green luster from beginning to end. The wings are black and there is a big white spot on the shoulder. The tail is much longer than the wings and is wedge-shaped. The mouth, legs and feet are pure black. The abdomen is bounded by the chest, and the front is black and the back is white. Raise birds. The diversity of habitats often appears in areas where human activities take place.
I like to nest in the big tree next to the house. Most of them live in pairs all the year round, omnivorous, foraging in the wilderness and fields, preying on insects, frogs and other small animals during the breeding season, stealing eggs and chicks from other birds, eating fruits, grains, plant seeds and so on. Each nest lays 5-8 eggs. Eggs are light brown, cloth brown and grayish brown spots. Female birds hatch eggs, the incubation period is about 18 days, and they leave the nest about 1 month.
