Among the breeding birds are European storm petrel ("Hydrobates pelagicus"), northern gannet, northern fulmar ("Fulmarus glacialis"), Manx shearwater ("Puffinus puffinus"), black-legged kittiwake ("Rissa tridactyla"), common guillemot ("Uria aalge"), razorbill ("Alca torda") and Atlantic puffin ("Fratercula arctica") (with 4,000 or more puffins
