The Purple Sandpiper is a medium-sized wading bird that is larger, stockier and darker than a Dunlin. It is mainly dark grey above and whitish below. It has a downcurved beak and bright orange legs. In flight, it shows a white wing-stripe. A couple of pairs nest in Scotland, but this species is mainly a winter visitor to almost any rocky coast in the UK. Most are found in Orkney, Shetland and along the east coast of Scotland and northern England – it is rare south of Yorkshire, except in Devon and Cornwall.
