Wikipedia Abstract

The Japanese cormorant (Phalacrocorax capillatus), also known as Temminck's cormorant, is a cormorant native to East Asia. It lives from Taiwan north through Korea and Japan to the Russian Far East. The Japanese cormorant has a black body with a white throat and cheeks and a partially yellow bill. It is one of the species of cormorant that has been domesticated by fishermen in a tradition known in Japan as ukai (鵜飼). It is called umiu (ウミウ sea cormorant) in Japanese. The Nagara River's well-known fishing masters work with this particular species to catch ayu.
