Changes in climate may harm birds

CLIMATE change could pile on the miles for migrating birds, claim North East experts.

Migrations are likely to lengthen according to the first ever study of the potential impacts of climate change on the breeding and winter ranges of migrant birds.

Scientists, led by Durham University, have published findings that show flights undertaken by birds to spring breeding grounds in Europe could increase by as much as 250 miles.

The research team, funded by the Natural Environment Research Council and the RSPB, has produced evidence of potential breeding ranges shifting northwards in the future.

Around 500 million birds are estimated to migrate to Europe and Asia from Africa.

Team leader, Dr Stephen Willis of Durham University, said birds face an increasing battle to survive.

“Most warblers come here in spring and summer time to take advantage of the surplus of insects, and leave for warmer climes in the autumn,” said Dr Willis.
