The Japanese Night-heron is a migratory bird that breeds in Japan. Except for some that stay in the southern part of the breeding grounds to overwinter, most of them migrate to Taiwan, China and the Philippines to overwinter. During migration, some of them pass through Shanghai, Hong Kong, Fujian and other places in my country. The migration time is from April to May in spring and from September to October in autumn.
The Chestnut-headed Bittern is secretive and a nocturnal bird. It is timid and alert. It often moves and forages alone or in pairs at night. It also often moves and forages during the day. It moves in hidden dark places in dense forests. When night falls, they leave the secluded forest and fly to distant feeding places. They often pass through reeds or walk on reeds. Usually they rarely fly. When flying, the two wings flap slowly, the neck shrinks into an S shape, and the feet stretch out to the back, protruding out of the tail. When resting, they often shrink their necks and stand still. When frightened at night, they jump up, fly low, and flap their wings slowly and powerfully. When disturbed, they often stretch their long necks upwards to watch and stare, and often shrink their necks when walking.
