Star species

Our star species are some of the most interesting birds you may see on your visit to the reserve.


The chough is the rarest member of the crow family in the UK. They can be found feeding in fields around South Stack, probing for invertebrates with their curved, red bill.



Guillemots look ungainly when they shuffle around on their nesting ledges on the cliffs, but underwater their streamlined shape comes into its own and they become agile and manoeuvrable.



Keep an eye out for a commotion among birds on the cliffs - a peregrine may be making a fly past. They are a regular sight overhead when a pair is nesting in the area.

Enjoy the comical antics of puffins in spring and early summer from the viewing points on the cliffs. Watch the adults returning from fishing forays at sea with sandeels hanging from their colourful beaks.

Very similar to guillemots, razorbills spend most of their lives at sea in the Atlantic, only coming to land to breed between March and July.
