Appearance:

Medium small Sylvia with short tail, slender body and steep forehead. Bill slim,fairly short and pointed. Male with rufous breast and conspicuous, broad, white moustache stripes. Upperparts lead grey. Female with slightly more brownish upperparts and buff white below. Immature birds has greyish brown upperparts, and are prone to confusion with Spectacled Warbler due to broad, brown fringes of tertials. The colour is however less rufous, and the dark centre ends in a rounded, not pointed tip. Pale legs in all sexes and ages, but some variation. Eye-ring colour variable, but generally red in male and very pale in female and immature (rules out other Sylvia except Tristram and Sardinian). Colour of upperparts more uniform than in confusion species in both male and female. May cock tail, but does not keep it raised like Dartford Warbler. Taxonomy much discussed. Western Italian population now accepted as a separate species (Moltoni's Warbler, S. subalpina), while S. c. inornata has species status in Svensson, but not in Clements (2018) .

Sound:

Alarm call a short, hard "tuk", but softer and fainter than Blackcap and Sardinian W. Song a rapid, vivid stream of squeaks and clearer notes, with timbre similar to Whitethroat. May be confused with Sardinian W., but lacks that species interwoven hard and rolling contact call.

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.
