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:

At a distance quite similar to Guillemot. Bill deep, rectangular and with white markings. Flanks unstreaked and armpits white. Tail longer than in Guillemot, with legs not protruding behind tail in flight. Tail often held clear of the surface when swimming. Cheeks white in winter, with broad, short and black eye stripe. Neck collar short and wide. Upperparts blacker, and underparts whiter than Guillemot. Heavy neck, head and bill, in combination with the long tail, gives it a front heavy, and different profile from Guillemot, whether perched, swimming or flying. Top of head in line with tip of uptilted bill when swimming.

Sound:

Very coarse and deep voice. Grunting or snore-like, with little phrasing. Mostly heard at breeding ground, but also sometimes at sea.
