Some species arriving from south a month ahead of schedule

As Arctic temperatures warm and weather becomes less predictable, migratory birds may face new challenges and some nasty surprises when they return North, researchers with the Canadian Wildlife Service say.
Birds sometimes arrive at their northern breeding grounds earlier than they used to, driven by warm weather in the South, only to find no food there when they arrive.
And, once they are in the Arctic, increasingly unpredictable weather can cause them additional misery.
Due to higher than average temperatures in many parts of Nunavut this past winter, birds are already flocking back to the High Arctic.
