Curlew Sandpiper

Open encyclopedia reference

The curlew sandpiper (Calidris ferruginea) is a small wader. It is a long-distance migrant, breeding in the bogs and coastal lowlands of the Siberian Arctic, arriving there in June and staying until August or September. After the breeding season, it migrates south to spend the winter in Africa and along the coasts of Oceania and southern Eurasia, occupying tidal mudflats and saltpans. It has three main plumages that change with maturity and season. The non-breeding plumage shows brown-greyish upperparts and white underparts. The breeding plumage is much more striking, with the entire front tinted a deep rusty colour, more intensely so in males. The first-year bird does not migrate or breed, instead remaining in its overwintering range throughout the breeding season. It may occasionally moult into its breeding plumage, which is largely similar to that of an adult but with white spots on the chest. The non-breeding juvenile plumage is also like that of an adult, except with creamy-coloured streaking on the breast and pale fringes on some of the wing feathers, leading to a scaly appearance.
