Crag Martin (Ptyonoprogne rupestris)
Siberian Jay (Perisoreus infaustus)
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.

CCPretty unmistakable. Dark brown to grey plumage, with conspicuous rusty patches on wings and tail. Noticeably smaller and slimmer than Jay. Seems all brown when perched, but rusty wings and tail immediately apparent when flying. Flight undulated and several birds are usually following eachother. A social, and very little shy bird.
Sound:Rich repertoire but not very vocal. Song a subdued chirping stream of squeaky notes and mimicry. Alarm call a loud, mewing, buzzard-like "eeeeaaah".
