Critically Endangered
Spoon-billed Sandpiper
Calidris pygmaea
The spoon-billed sandpiper is a small wader that breeds on the coasts of the Bering Sea and winters in Southeast Asia.
Appearance
The most distinctive feature of this species is its spatulate bill. The breeding adult bird has a red-brown head, neck and breast with dark brown streaks, blackish upperparts with buff and pale rufous fringing. Non-breeding adults lack the reddish colouration, but have pale brownish-grey upperparts with whitish fringing to the wing-coverts.
It is 14–16 cm (5.5–6.3 in) long. The measurements are. Wing 98–106 mm, bill 19–24 mm, bill tip breadth 10–12 mm, tarsus 19–22 mm and tail 37–39 mm.
Range and habitat
The spoon-billed sandpiper's breeding habitat is sea coasts and adjacent hinterland on the Chukchi Peninsula and southwards along the isthmus of the Kamchatka Peninsula.
In November 2011, thirteen spoon-billed sandpipers arrived at the Wildfowl and Wetlands Trust (WWT) reserve in Slimbridge, Gloucestershire, United Kingdom to start a breeding programme.

Diet and breeding
Spoon-billed sandpipers feed on the moss in tundras, as well as smaller animal species, like mosquitoes, flies, beetles, and spiders. At certain points in time, they also feed on marine invertebrates such as shrimp and worms.
The spoon-billed sandpiper is a small wader that breeds on the coasts of the Bering Sea and winters in Southeast Asia. This species is highly threatened, and it is said that since the 1970s the breeding population has decreased significantly. By 2000, the estimated breeding population of the species was 350–500.
In crisis
This bird is critically endangered, with a current population of fewer than 2500 – probably fewer than 1000 – mature individuals. The important staging area at Saemangeum, South Korea, has already been partially reclaimed, and the remaining wetlands are under serious threat of reclamation in the near future. As of 2016, the global spoon-billed sandpiper population was estimated at 240–456 mature individuals or at maximum 228 pairs.
Formerly classified as an Endangered species by the IUCN, recent research shows that its numbers are decreasing more and more rapidly and that it is on the verge of extinction. It is consequently reclassified to Critically Endangered status in 2008.
