Birds face longer migration due to climate change

[Simon]

Migrating birds such as the garden warbler and whitethroat will face longer journeys because of climate change, experts warned today.

A team of scientists led by Durham University has demonstrated that while the birds' breeding ranges are likely to shift northwards, their wintering areas will not, thus increasing the length of their journeys by up to 250 miles. The study, published in the Journal of Biogeography, has serious implications for many of the birds returning this month to Britain to breed.
