Characteristics
The whole body is brownish black, and parts other than the wings can look dark green depending on how the light hits it. The iris is a beautiful green color. It has a sharp hooked beak for catching fish. It differs from similar cormorants in that the base of its beak is yellow and the wide-angle part is rounded. It takes off with a run-up on its webbed feet. During the breeding season, the head and waist become white.
Ecology
They live in rivers and lakes and catch and eat fish in the water. On sunny days, it spreads its wings at the water's edge to dry. They move in groups and gather branches on trees to build nests and reproduce. Sometimes forms colonies with herons.
Habitat
I found him resting on the bank of the river in Asakawa, Hachioji City. In addition to juvenile cormorants, there were gray herons and great egrets nearby. I could see them diving to catch fish and drying their wings in sunny places.
