Migrating waxwings arrive in the UK from Scandinavia

A Waxwing feeds on Rowan berries on December 10, 2012 in London, England. Thousands of Waxwings have descended on Great Britain after the failure of the birds food sources in their native Scandinavian breeding grounds. Birdwatchers across the UK travel hundreds of miles to catch a glimpse of the rare birds, who turn up in significant numbers every few years, and are thought to be a sign of a harsh winter to come.
