Kaisha island is located in the middle of Yangtze River, a fertile land with ample water and grass, with superior ecological environment. It has always been a habitat favoured by birds. In the present Chlidonias hybrida is in breeding season. Countless Chlidonias hybrida are nesting and brooding in the wetland on the island. It is a marvelous scene. They are living harmoniously with a large number of wild birds such as egrets, moorhens, and coots. Photo by Jiang Jianhua
