Great Cormorant


The Great Cormorant on the left looks a lot like the rare subspecies Phalacrocorax carbo carbo which occurs along the North Atlantic coast.
In continental Europe, almost all Great Cormorants belong to the subspecies Phalacrocorax carbo sinensis.
The only decisive difference between the two subspecies is the sharpness of the angle that the yellow bare skin of the throat pouch makes.
If that angle is sharper than 65 degrees (a forward angle), then it's a P. carbo carbo, otherwise a P. carbo sinensis.
The 2nd photo seems to show that sharp angle but it is hard to determine.
