Tree Sparrow - 2003-07
Friday, August 24, 2012 at 9:22PM The Tree Sparrow is like a House Sparrow but is slightly smaller and has a chestnut coloured crown and dark cheek patches, the sexes being alike. It nests in holes in trees and buildings.
Historically this species has always been a sporadic breeder in Pembrokeshire. During the 1984-88 survey breeding was confirmed at Dreenhill, Penblewin and Pengawse. During the 2003–07 survey just one pair was confirmed as breeding, at Ramsey Island.
The Tree Sparrow has suffered long term decline across northern Europe, including Britain, probably as a result of changing agricultural practices.
