Appearance:

Large, fairly characteristic lark. Wings blackish underneath with conspicuous white trailing edge, obvious in flight. Outer tail-feathers white. Perched birds easiest identified by large black breast patch (though variable in size and shape), and very deep bill. Broad, buff supercilium and eye-ring. Leaves a robust and compact impression, with its broad wings, short tail and heavy bill. Stance usually upright when perched. Flight undulating, but less hesitant than Skylark.

Sound:

Contact call a diagnostic, ringing, resonant trill; "krrretlee". Song is similar to Skylark, but slower, louder and with more mimicry. Best recognized from the interspersed contact calls and other dry trills.

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.
