 The global population of the common starling is estimated to be more than 310 million individuals and its numbers are not thought to be declining significantly , so the bird is classified by the International Union for Conservation of Nature as being of least concern . It had shown a marked increase in numbers throughout Europe from the 19th century to around the 1950s and 60s . In about 1830 , S. v. vulgaris expanded its range in the British Isles , spreading into Ireland and areas of Scotland where it had formerly been absent , although S. v. zetlandicus was already present in Shetland and the Outer Hebrides . The common starling has bred in northern Sweden from 1850 and in Iceland from 1935 . The breeding range spread through southern France to northeastern Spain , and there were other range expansions particularly in Italy , Austria and Finland . It started breeding in Iberia in 1960 , while the spotless starling 's range had been expanding northward since the 1950s . The low rate of advance , about 4 @.@ 7 km ( 2 @.@ 9 mi ) per year for both species , is due to the suboptimal mountain and woodland terrain . Expansion has since slowed even further due to direct competition between the two similar species where they overlap in southwestern France and northwestern Spain .
