A spoon-billed sandpiper chick walks past a stuffed dog toy at the Wildfowl and Wetlands Trust center in Slimbridge, Gloucestershire, England. It is one of the chicks from 20 eggs taken to the UK from Russia in the latest stage of a breeding program which hopes to save the species from extinction. The spoon-billed sandpiper is one of the world's rarest birds; there are thought to be fewer than 100 breeding pairs left in the wild.
