Little Gulls look quite like Black-headed Gulls, but they are smaller, more slender, and have more rounded wings. Their heads are truly black down to their necks. Their round-tipped wings are pale grey above, and black beneath with the exception of a white band around the trailing edge. The leading edges of their primary wing feathers lack the white wedge-shaped marking visible on Black-headed Gulls. Like Black-headed Gulls, they lose their dark head colouring in their winter plumage and only have a small dark patch behind each eye. But their wings remain distinctively dark underneath.

Juvenile Little Gulls resemble immature Black-headed Gulls, but their primary wing feathers have no white leading edge or dark streak along the trailing edge (though their secondary wing feathers have indistinct brownish edges).

Little Gulls’ legs are bright red in summer and duller reddish in winter. Their beaks are reddish brown in summer but black in winter. They have dark irises, and narrow red rings around their eyes.
