St Kilda
The giddying cliffs of St Kilda are home to almost a million seabirds.

 Bird SilhouetteNo visitor can fail to be impressed by the spectacle of nearly a million seabirds wheeling around St Kilda’s awesome cliffs.

One of the largest colonies in the North-east Atlantic, St Kilda is of global importance for a great range of species:

  • Largest colony of Northern Gannets in the world, holding one seventh of the total population
  • Largest colony of Leach’s Storm Petrel in the EU, with 94% of the European population
  • Largest colony of Atlantic puffins in the EU, holding a quarter of the UK population
  • Largest colony of Northern Fulmars in the EU, more than double the size of the next largest colony
  • Last Great Auk in the UK killed here in 1840
