Coal Tit (Periparus ater)
Glaucous Gull (Larus hyperboreus)
Appearance like a small Great Tit in black and white. Back led-grey (olive in British sub sp.), underparts off-white. Diagnostic elongated, white neck-patch and big triangular bib. Double wing-bars, small head and short tail.
Sound:Song: Various repeated motifs, consisting of two to three notes with alternating accents. Slightly similar to Great Tit, but faster, not so metallic and with a less full tone. Can be mistaken for Marsh Tit when singing single or double notes, but tone is softer and notes more clearly separated (if disyllabic). Call: short soft and clear "piu", first rapidly rising and then falling in pitch.

CCAll white wingtips like Iceland Gull. The following characters applies to all ages: Told apart from Iceland Gull by angular head profile, proportionally shorter wings and long, heavy bill. Bill longer than half the length of head, and shows prominent hook. Primaries extends just about past tail in sitting birds, and the whole rear of the bird seem heavier. Eye smaller than in Iceland Gull, with a stern expression. Comparison with nearby Herring Gulls fruitful. Iceland Gull often smaller than Herring Gull, and less heavy, while Glaucous Gull usually larger. Impression reinforced by Iceland's agile maneuvering.
Sound:Like Herring Gull.
