Birds by name
Conservation status: Amber
The largest of the UK's divers, it has a bigger, heavier head and bill than its commoner relatives. It is largely a winter visitor to our shores although some non-breeding birds stay off northern coasts in the summer.
Around coasts where it is usually solitary, often farther out to sea than other divers. Occasionally seen inland on reservoirs. Largest numbers off the Northern and Western Isles of Scotland and also the Cornish coast.
They start to arrive offshore in August and birds move back to their largely Icelandic breeding grounds in April and May.
Fish and crustaceans
* UK breeding is the number of pairs breeding annually. UK wintering is the number of individuals present from October to March. UK passage is the number of individuals passing through on migration in spring and/or autumn.
