Appearance:

Small and secretive warbler, usually discovered by the contact call. Broad, yellow/whitish wing-bars framed in black, and dark tertials with pale fringes gives the species a contrasting plumage. Long and strong yellow supercilium (lacking the orange base of Pallas' Leaf Warbler). No central crown-stripe. Slightly smaller than a Chiffchaff, with smaller bill and shorter tail. Rump same colour as back (as opposed to Pallas'), and overall greener and more strikingly coloured than Hume's Leaf Warbler (but beware individual variation).

Sound:

Contact call and song both distinct. Contact call a very high-pitched "zeeoooee", with pitch rapidly dropping in the middle, and ending on a quickly rising note. Song an ornamented, drawn out, slow-motion version of the contact call, with similar timbre and pitch.

Appearance:

All 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.
