A Bewick's swan comes into land at the Wildfowl and Wetlands Trust on November 3, 2009 in Slimbridge, England. Bewick's Swans have begun their annual migration from Arctic Russia to the bird sanctuary, but experts have expressed concern at their declining numbers across North Europe. Their arrival, later than usual and which traditionally signals the start of a cold snap, was a surprise because of recent high winds that were blowing from the wrong direction. Currently 13 of the small, elegant swans have landed back at Slimbridge Wildfowl and Wetlands Trust (WWT) in Gloucestershire, since Sunday and several hundred more are expected to follow.
