St. Kilda is an archipelago located in the Outer Hebrides, 41 miles west of North Uist. An internationally significant natural and cultural heritage site, it is recognized by UNESCO as a dual World Heritage Site. The area is the largest seabird sanctuary in the North-East Atlantic, welcoming over 1 million seabirds in the spring and the summer months. Funding from the US Foundation will support wildlife protection efforts on the islands, which now include the marine environment as well because of its importance to the seabird colony.
