(passer montanus)
The (Eurasian) Tree Sparrow is an uncommon bird in Scotland. Its numbers and range have decreased significantly probably due to changes in farming practice. It is locally common in the locations where it still survives, most of these being in the east and south east of Scotland. Within the Clyde area there are two regular pockets, one to the north of Glasgow at Millichen farm and one near Glasgow airport in the vicinity of Yonderton and Blackstoun farms. On a worldwide basis it is an abundant species - we saw many hundreds of them in Bhutan where they completely replace the House Sparrow.
