Unique Ecosystem - Birds
In the mountains of the Oki Islands, the unique chirping of the ruddy kingfisher can often be heard. It is a summer bird in Japan, and the species build their nests by digging holes in the hollows of large trees or steep, vertical dirt bank. In rare cases, the old nest of the yellow hornet is also used. The bird is about 27cm in size. In Japan, the bird is also known as the “bird of fire”, as it is bright reddish brown in colour with a bright red bill, and a small blue rump patch. The bird feed on fish, frogs and freshwater crabs that live near the water in the forest.
