Every summer, puffins migrate from the South America all the way to Skellig Michael, a tiny island off the south west coast of Ireland. Puffins make this journey to breed and to raise their young. They nest in burrows, where young chicks can be kept safe while adults fish in the rich waters surrounding Skellig Michael. Another migratory searbird, the Manx Shearwater, also lives on the island. This bird is nocturnal, so is only active after dark.
