The Bass Rock is an impressive island/rock on the North Berwick coast in the Firth of Forth, East Scotland. The island is now a wildlife sanctuary but also has a long history of human habitation, with castles, chapels and prisons built on the volcanic rock... but a more modern lighthouse still exists today. This steep-sided volcanic rock is 351 ft (107 metres) above sea level and lies about 3 miles northeast of North Berwick.
The Bass Rock is home to the world's largest colony of Northern gannets. These birds are one of the largest seabirds in the British Isles, with a total wingspan of 2 m (6.5 ft). Approximetly 150 000 gannets nest on Bass Rock arriving in late February and departing at the end of October when they set out on their long journey down to the west coast of Africa.
The lower ledges of the Bass are home to shags, guillemots and razorbills, with seals hauling up on the rocks below. 
Would you like to see these birds dive underwater for fish? Then check out these incredible underwater photos from two different photographers. I admire them both and I think they are a great addition to this blog.
