          hort-legged, small-billed, delicate and elegant, this gull is
        Sreminiscent of the marsh terns, feeding like a Black Tern over  FLIGHT: light, buoyant, erratic; shallow, quick flicks
        open water. It tends to appear over lakes and reservoirs in small  of wings, frequent turns.
        groups in spring and autumn, also like the terns,
        but immatures may linger for weeks in the         PALE UPPERWINGS
                                                          Adults have no trace of black on
        summer. It combines the typical “hooded” gull     the upperside of the wings.
        sequence of plumages with a strongly contrasted
        immature pattern rather like that of the Kittiwake.
        In most of Europe, it is much less abundant than
        other gulls, with which it often associates.
