Shades of purple ...

Purple Sandpiper (Calidris maritima)


Few waders are as closely restricted to a particular habitat as C. maritima, which is fundamentally a bird of the very edge of the surf, where it searches through wave-washed, seaweed-covered rocks for invertebrates.

It breeds on the Arctic islands of Canada, Greenland, Iceland, Svalbard, northwest Scandinavia and Russia. In Europe, the British Isles are on the extreme southwestern edge of its range, with up to four pairs breeding in Scotland since the late 1970s. It winters regularly at a small number of sites in Sussex, where it is a scarce winter visitor and passage migrant, with only Newhaven Harbour consistently holding a wintering flock during the last 50 years, where they are found on the harbour arms.
