Crag Martin (Ptyonoprogne rupestris)
Skylark (Alauda arvensis)
Stocky martin with broad (but pointed) wings, broad tail and broad head. Mostly dusky brown with paler underparts, except almost black under wing-coverts, and fairly dark vent. Most tail-feathers with small, white "window" visible from below. Immature similar to adults, but with pale fringes to coverts. Flight less acrobatic than other martins, with frequent, long glides. Strays less away from breeding grounds than congeners.
Sound:Most heard is a House Martin-like, but less rolling, "prit" or "check". Other contact sounds include a plaintive "peeuuu". Song an inconspicuous, staccato series of twittering notes, with a wagtail-like timbre.

CCShort foldable crest. Pale eye-ring and supercilium. Long primary projection (primaries extend well beyond tertials), white trailing edge to wing and white outer tail feathers. Tail much longer than in Wood Lark.
Sound:Song a pleasing energetic stream of chirping, merry trills, interspersed with mimicry. Trills quite resonant with fairly full tone. Song usually given in flight high in the air. Less characteristic, shorter, weaker and more varied song when given from ground. Most typical flight call a short trilling "chirrup", with the end note noticeably lower pitched than the start. Also several other more cryptic calls.
