Researchers at Durham, the RSPB and Cambridge University have found that birds such as the Cirl Bunting and Dartford Warbler are becoming more common across a wide range of habitats in Britain as temperatures rise.
Unfortunately, some northern species, such as the Fieldfare and Redwing, are not faring quite so well and their numbers are falling
Researchers looked at twenty-five year population trends of 42 bird species in relation to changes in climatic suitability simulated using climatic envelope models.
Professor Brian Huntley from The Institute of Ecosystem Science at Durham University says: "The results are what we expected to find given the changes in climate over the last 20 years.
"Because the UK is in the middle Latitudes of Europe, we expected that recent climatic warming would favour species with ranges located in the south of Europe and adversely affect northern species."
