European Shag vs Little Black Cormorant

European Shag (Gulosus aristotelis)

European Shag

Gulosus aristotelis

Huge1.8 kgMarine

This is a medium-large black bird, 68 to 78 cm (27 to 31 in) long and with a 95-to-110-centimetre (37 to 43 in) wingspan. It has a longish tail and a yellow throat patch. Adults have a small crest in the breeding season. It is distinguished from the great cormorant by its smaller size, lighter build, thinner bill, and, in breeding adults, by the crest and metallic green-tinged sheen on the feathers. Among those differences are that a shag is smaller and has a lighter, narrower beak, and the juvenile shag has darker underparts.
