Yellow-browed Warbler (Phylloscopus inornatus)
Common Gull (Larus canus)
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.

Differs from Herring Gull in smaller size, lighter bill and light flight. Head profile rounded, and the small bill lacks the red spot of the larger gulls. Told apart from Kittwake by greenish legs and large white spot on wing tips. Juveniles quite similar to young Ring-billed Gulls, but latter have paler grey back, heavier, pinkish bill with dark tip, pale mid-wing panel and less contrasting terminal band of tail.
Sound:Various mewing sounds. Similar in form to Herring Gull, but much higher pitched.
