Only the Red-legged Kittiwake shares the solid black wingtips and plain yellow bill of the adult Black-legged Kittiwake. The adult Red-legged Kittiwake has a darker mantle, shorter bill, darker color underprimaries, and red legs. Immature Black-legged Kittiwakes have bold wing patterns that are similar to immature Bonaparte's, Black-headed, and Little gulls but have a distinctive black collar. Immature Red-legged Kittiwakes lack a black tail band and dark carpal bar.
