Habitat near rivers, lakes, swamps and paddy fields, mostly active in the morning and at night, hiding in grass or gravel during the day. When you are afraid of flying, fly zigzag, climb quickly, hover at high altitude and rush into the grass to hide. When courtship shows off, it climbs up and dives, and the flying feathers outside vibrate. It feeds on annelids, insects, spiders, crustaceans, mollusks and small fish, as well as seeds and fruits. During the breeding period from May to July, nests are built in the grass on the ground, and each nest produces 4 eggs.
