morski vranac Gulosus aristotelis

Fairly common along seacoasts, nesting on steep cliffs; usually seen as singles or small groups, swimming or flying low over the sea. Does not occur on inland water bodies. Rather large, long-necked dark waterbird; feeds by diving and often leaps a little as it dives. Appreciably smaller and thinner necked than Great Cormorant, with more slender bill. Adult glossy black overall with narrow yellow throat patch; first-year dark smoky grayish overall, variably paler on throat and underparts. By spring, often develops faded pale panel on upperwing.
