As its name suggests, the spoon-billed sandpiper is a remarkable species. It's a tiny wading bird - about the size of a house sparrow - with a uniquely-shaped beak. These birds are dying at a shocking rate, and extinction looks likely within the next decade if urgent action is not taken.
Recent research suggests that there are only between 100-200 breeding pairs. And scientists believe that the population is plummeting by 26 per cent each year. In particular, the number of young sandpipers surviving to adulthood is extremely low.
Spoon-billed sandpipers undertake a migration of nearly 5,000 miles (8,000 km) from their Siberian breeding grounds to the coasts of south-east Asia.
It's a hazardous journey. We think there are two main reasons for the decline. One is hunting, particularly on the birds' wintering grounds in Myanmar and Bangladesh. The other is that the birds' habitat is under serious threat from the rapid coastal development taking place in that part of Asia.
We're part of a team including the Wildfowl & Wetlands Trust (WWT), Birds Russia, BirdLife International, British Trust for Ornithology and others, working to throw this species a lifeline.
