　　Climate change will force exhausted birds migrating (迁徙) to Europe from Africa to travel further, according to a new study.

The annual voyage of some species, which fly north in search of food and suitable habitats, could increase by as much as 400 kilometres, the research found. "Marathon migrations for some birds are set to become even longer，" said Stephen Willis, a professor at Durham University in Britain and the main architect of the study. "This is bad news for birds like the Whitethroat, a common farmland bird. The added distance is a great threat. As temperatures rise and habitats change, birds will face their biggest challenge since the Pleistocene era, which ended 11，000 years ago，" he said in a statement.
