Britain faces an invasion of exotic birds as climate change forces native species further north, scientists have warned.
The cold winter has proved particularly trying for one bird species, ornithologists say. They believe numbers of the tiny Dartford warbler – which is smaller than a sparrow – may have been reduced by three-quarters in the past few weeks because of last month’s snow.
The bird nests in gorse shrubland in the south of England and has made a slow comeback after being nearly wiped out in the freezing winter of 1963, when numbers were apparently down to 11 pairs.
It is still a rare sight. In 2006, after a decade of mild winters, its numbers had returned to 3,212 pairs, according to a count in Hampshire.
