Manx Shearwater has white undertail coverts and a shorter tail. Greater Shearwater is larger with a white rump and dark belly. Immature gulls are superficially similar but can be separated at great distances by their different flight styles. Shearwaters fly closer to the surface of the water, often disappearing behind swells, alternating flaps with long glides on downcurved wings.
