The range margins of northern birds shift polewards. Brommer, J., E. Annales Zoologici Fennici, 41(April):391–397, 2004. abstract bibtex The changes in range margins of birds breeding in Finland was analysed from pub- lished atlas data for a 12-year period (1974–1979 to 1986–1989). The change in range margin was statistically corrected for changes in species’ distribution using linear regression. For species predominantly occurring in southern Finland (n = 116), the expected range margin shift, if their distribution would not have changed, was 18.8 km northwards. Northerly species (n = 34) showed no such significant range margin shift. A similar result was found earlier for UK birds. Recent range margin shifts in birds therefore seem to be a general phenomenon, which may be related to climate change.
