The Manx Shearwater breeds on islands and coastal cliffs in the North Atlantic. It breeds in large colonies and it nests in burrows excavated in soft ground with a chamber at the end. After breeding it migrates south to places such as South America.

It feeds on small fish and shellfish which it captures either on the surface or by diving. They often gather offshore in large "rafts" as can be seen in the third photo. This is usually in the afternoon in preparation for visiting their nest-sites which they always do at night.
