Some songbirds now migrate east to west. Climate change may play a role

A dramatic shift in some Richard’s pipits’ winter plans might be linked to a warming Europe.

From the introduction:

As the chill of autumn encroaches on Siberia’s grasslands, Richard’s pipits usually begin their southward trek to warmer latitudes. But a growing number of the slender, larklike songbirds seem to be heading west instead, possibly establishing a new migratory route for the species. 

This would be the first new route known to emerge on an east-west axis in a long-distance migratory bird, researchers report October 22 in Current Biology. The finding could have implications for how scientists understand the evolution of bird migration routes over time and how the animals adapt to a shifting climate.
