Appearance:

Small and short-winged Sylvia with large head and high crown. In all plumages; evenly warm rufous wing-panel (lacking dark centered greater coverts of Whitethroat), very short primary projection, dark tail, thin pointed bill, narrow dark centres to tertials, pure white chin and (incomplete) white eye-ring. Adult male with lead-grey head, dark/black lore and often grey lower throat. Female and immature differs from Whitethroat by short primary projection, smaller size, slender build and thinner bill. Told from immature Subalpine Warbler by warmer rufous wings with only narrow dark centres to tertials.

Sound:

Alarm call a dry, mechanical rattle; "trrrrrrrrrrrt", often rather long, but also given in pulses "trrrrrt-trrrt-trrrrrrrrr". More confluent and softer than similar call of Sardinian Warbler. Song rather weak and squeaky, but may be confused with several congeners. It typically starts with a few fluting notes then quickly giving way to fast alternating between clear tones and rattling pulses of "trrrrt". Phrases are short with marked pauses in between, and the structure is quite fixed even though each phrase is slightly different (in contrast to Sardinian and Subalpine Warbler). Sometimes bursts out in longer, more continuos flight-song.

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.
