Curlew Sandpiper
Calidris ferruginea (Pontoppidan, 1763)
CV
CURSA
5090
Family: Charadriiformes > Scolopacidae
A bit larger than a Dunlin, with a similarly down-curved bill, most records of this migratory wader are in the autumn.
This species breeds in northern Siberia and a small proportion of individuals migrate through Britain & Ireland to wintering grounds in western Africa. Autumn numbers are variable, and most of the records received through BirdTrack fall between August and early October. Birds present in July likely represent those whose breeding attempt has failed.
In winter it has a rather drab, grey appearance, but in summer dons an unmistakable brick-red dress that provides surprisingly good camouflage in its tundra breeding habitat.

Identification
Curlew Sandpiper identification is sometimes difficult. The following article may help when identifying Curlew Sandpiper.
Identifying Sanderling and Curlew Sandpiper
In the UK in late Summer some may be daunted by the prospect of identifying individual species in frequent groups of small waders. The key to differing between many of these small, plump birds is to become accustomed with Dunlin first. In this Bird ID video we compare Sanderling and Curlew Sandpiper to their more well-recognised cousin.

DISTRIBUTION
Curlew Sandpipers are most frequently reported while on autumn passage in July–October and are scarce in spring. Over half the occupied 10-km squares on the winter distribution map are late-autumn migrants recorded in November. The few records of true wintering birds are all from coastal marshes or estuaries.
