Tree Sparrow (Passer montanus)
Siberian Jay (Perisoreus infaustus)
Differs from House Sparrow by warm brown crown, white cheeks, white (incomplete) collar and diagnostic, black cheek patch. From Spanish Sparrow by cheek patch, and lack of black breast markings. Brown and streaked rump. The black bib does not expand towards the chest. Head profile rounder and neater than House Sparrow, with slightly smaller bill. Identification by profile alone is possible with practice. Sexes and ages alike.
Sound:Distinct, high-pitched and explosive contact-call; "che-witt" typically given in flight. Second syllable rising rapidly in pitch. Most other sounds similar to House Sparrow, and may be difficult to identify. Chattering sounds are generally harder, and song slightly higher pitched than House Sparrow.

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".
