Climate change makes migrations longer for birds



Bird migrations will get longer according to a study of the potential impacts of climate change on the breeding ranges of migrant birds.
A team of scientists, led by Durham University, have published findings that show that the marathon flights undertaken by birds to spring breeding grounds in Europe, are going to turn into even more epic journeys; the length of some migrations could increase by as much as 250 miles.
The research team, funded by the Natural Environment Research Council and the RSPB, looked at the current migration patterns of European Sylvia warblers, a group of birds that are common residents and visitors to Europe, like the Blackcap.
Published in the Journal of Biogeography, the scientists demonstrate evidence of potential breeding ranges shifting northwards in the future, while the wintering ranges remain stationary for many species.
