A flock of great crested grebes floats on the sea, gently bobbing up and down under the warm November sun.
Every so often a bird dives below the surface, searching for a tasty morsel from among the 260 species of fish, crabs and shellfish that live there.
A little closer to shore sits a flock of greater scaups, freshly arrived from their summer breeding grounds in Russia. When winter comes, there will be about 25,000 water birds here at Kasai Kaihin Park, which was last month designated as a wetland of international importance, also known as a Ramsar Site.
