Japanese cormorant

The Japanese cormorant ("Phalacrocorax capillatus"), also known as Temminck's cormorant, is a cormorant native to the east Palearctic. 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) (literally meaning 'raising a cormorant'). 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".
