Coal Tit (Periparus ater)
Iceland Gull (Larus glaucoides)
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 Glaucous Gull. Told apart from latter by rounded head, longer wings and shorter, more slender bill. Bill shorter than half the length of head, and lacks prominent hook. Primaries extends well past tail in sitting birds, and the whole rear of the bird seem slimmer. Eye bigger than in Glaucous Gull, with a more "gentle" 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, but tone sharper.
