Portrait of a Puffin on Skomer Island.

A portrait of a Puffin on the cliff on Skomer island opening its colourful beak. Skomer island with its rocky shorelines and jagged inlets is home to the largest colony of puffins in the UK. Among shaded coves and exposed headlands, Atlantic Puffins spend the summer burrowed into the woven warrens that pocket the cliffsides.
