Where to see them
Shetland is the UK stronghold for this species with other key populations on Orkney, the Outer Hebrides and the north Scottish mainland. They are also found along the whole of west Scotland south to the Mull of Kintyre. Outside the breeding season it is numerous along the UK's east coast, and occurs patchily along the west coast, with concentrations off west Scotland and around north-west Wales.
When to see them
They arrive on their breeding grounds in April and depart in September and October. Birds from further north start to be seen off the UK's east and west coasts in August and September reaching a peak in October. Most birds move back north in March and April.
