Scientists have shown for the first time that common bird populations are responding to climate change in a similar pronounced way in both Europe and the USA.
An international team of researchers led by Durham University, UK, found that populations of bird species expected to do well due to climate change had substantially outperformed those expected to do badly over a 30 year period from 1980 to 2010.
The research, conducted in collaboration with the RSPB and the United States Geological Survey (USGS), is published in the journal Science.
It is the first real demonstration that climate is having a similar, large-scale influence on the abundance of common birds in widely separated parts of the world, the researchers said.
Among the species showing pronounced effects of climate change are common woodland and garden birds such as the wren, in Europe, and the American robin in the USA.
