Also known as Temminck's Cormorants, and sometimes by the scientific name P. filamentosus, these large cormorants are endemic to northeast Asia breeding on rocky shores from Sakhalin through Japan to South Korea. Very similar to Great Cormorant, but given close views, the two may be distinguished by the extent and shape of their bare yellow facial skin which is much reduced in Japanese Cormorant. This photo of a winter adult shows the pointed rear projection of the gape line unlike the rounded rear gape of Great Cormorant. Japanese Cormorant is also slightly larger than the local subspecies of Great Cormorant (Phalacrocorax carbo hanedae). Both occur along the coast, but the Great Cormorant is most common inland where the Japanese Cormorant does not normally occur. Fittingly the Japanese name for the Great Cormorant is "River Cormorant" while Japanese Cormorant translates to "Sea Cormorant." Canon PowerShot SX60
