Crested Tit (Lophophanes cristatus)
Iceland Gull (Larus glaucoides)
The pointed crest makes it rather unmistakable, but can be overlooked if crest is folded. Brown upperparts, pale buff underparts and black bib. Speckled crown and black eye-stripe connecting to characteristic cheek markings.
Sound:Call a characteristic vibrating rolling trill "Trrrrurrrurrrit", with last syllable emphasized and ending with ascending pitch. Often preceded by a couple of introductory "tzi tzi". Song: an improvisation over previously described calls.

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.
