Grey Wagtail (Motacilla cinerea)
Great Black-backed Gull (Larus marinus)
Elegant and very long-tailed wagtail. Vent always bright yellow in all plumages. Legs pinkish flesh-coloured, not black. Wings with single white bar, visible both from below and above. Male with black throat in summer. Constantly wags tail, often in a more horizontal posture than congeners. Flight more attenuated and more bounding than in other wagtails. Attached to water and streams.
Sound:Contact call short, metallic and with a clipped ending. Often disyllabic, "tzeet-tzeet", with each syllable more separated than in White Wagtail, and timbre more "dirty". Song simple but variable. Often starts with the contact call, followed by short melodic phrases. Sometimes with more elaborate song-flight like White Wagtail.
