Coturnicops exquisitus

The foreign name of the Swinhoes Yellow Rail is Swinhoes Yellow Rail, and there is no subspecies.

Some of the Swinhoes Yellow Rail are summer migratory birds, while others are winter migratory birds. In Northeast China, they are mostly summer migratory birds, in the east, they are winter migratory birds, and in other places, they migrate to the Northeast breeding grounds in mid-April in spring and leave in mid-to-late September in autumn.

The flower quail often comes out to the open grassland in the morning and evening, and moves and forages in the grass near the river or lake. It is mostly active at dawn and dusk, and often hides in the grass during the day. When it encounters danger, it quickly runs to the grass or waterside. After reaching the waterside, it either enters the water to swim or flies to the other side of the water. Sometimes when threatened, it often lowers its head and tail to run on the ground, or hides in the grass or bushes. It mainly feeds on aquatic insects and other small invertebrates. It mainly feeds on aquatic insects, crustaceans and algae. It is very secretive.

The breeding season of the flower quail is from May to July. It nests in the grass near the water. In the breeding ecology, it goes through courtship, nesting, egg laying, hatching and raising chicks. Courtship is an important feature of sexual maturity. Male birds often fight with each other when they enter sexual maturity. Prolonging the light hours, suitable environmental temperature and nutritious feed are all important factors that promote birds to estrus. Bird nests are important places for birds to lay eggs, hatch and raise chicks. Egg laying begins after nesting. During the egg-laying period, the interval between each two eggs is not quite the same, and each nest usually lays 6 eggs. The color of the eggs is pink and yellow, with reddish brown and lavender spots. Incubation is an important stage of its reproductive life. Incubation is mostly done by female birds, and male birds guard beside the nest or in the nest area. The young birds can walk and leave the nest with their parents to forage soon after hatching, and will no longer return to the nest.

The distribution area of the flower chicken is narrow and the number is extremely rare. The reason is habitat destruction: industry, water conservancy, fishing, grazing, land reclamation, watering and reed farming, and reed cutting have destroyed its habitat. Natural enemies eat its eggs and chicks, such as birds of prey, ravens, weasels, tigers, wolves, red foxes, etc., and are hunted. Due to its rare value, criminals hunt it in large numbers for profit.
