It was remarkable looking over the side of the cliffs at Latrabjarg the number of bird nests clinging to the vertical rocks. Ltrabjarg, in Iceland, marks the western-most part of Europe. It hosts millions of birds and is vital for their survival as it hosts up to 40% of the world population for some species e.g. the Razorbill. It is Europe's largest bird cliff, 14km long and up to 440m high.
