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:

Differs from Common Tern in shorter head, and blood-red bill. Legs shorter, but tail streamers longer (extends well past wings in sitting birds). Underparts of primaries with sharply bordered dark trailing edge (diffusely bordered in Common Tern). Both primaries and secondaries transparent to sunlight. Crest less apparent than in Common Tern and underside greyer. Cheeks white just below the black cap, often in contrast to grey lower cheeks. Juveniles lacks buff coloured back.

Sound:

Similar to Common Tern but higher pitched. Typical call a series of high pitched "tip-tip-tip", and longer, ringing, high-pitched "kriiiiii" calls. The drawn out "kree-aaahh" call falls less distinctly in pitch than Common Tern.
