Spanish sparrow
The Spanish sparrow has a highly complex distribution in the Mediterranean region, Macaronesia, and southwest to central Asia. It breeds mostly in a band of latitude about 15 degrees wide, from the Danube Valley and the Aral Sea in the north to Libya and central Iran in the south. Its range has expanded greatly by natural colonisation over the last two centuries, in the Balkans, where it reached Romania, Serbia, and Moldova from 1950 onwards; and in Macaronesia, where its range expansion has been attributed to introductions and travel by ship, but was more likely natural colonisation by migrating birds. Vagrants occur widely, as far north as Scotland and Norway.
