Great Northern Diver (1st Winter) (Gavia Immer) on the Marine Lake at Southport, Lancashire, England - January 2014
Might still be there! Another inland rarity!
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.
Where to see them
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.
When to see them
They start to arrive offshore in August and birds move back to their largely Icelandic breeding grounds in April and May.
What they eat
Fish and crustaceans
