Skellig Islands consent. During the 2014 nesting season, black-legged kittiwake chicks in nests were swept into the sea by the downdraught from a helicopter and devoured by gulls. Both of the Skellig islands are known for their seabird colonies, and together comprise one of the most important seabird sites in Ireland, both for the population size and for the species diversity. 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
Wedge-tailed shearwater (in common with the other shearwaters) as an adaptation for swimming. This species is related to the pan-Pacific Buller's shearwater, which differs much in colour pattern, but also has a wedge tail and a thin black bill. They make up the "Thyellodroma" group, a superspecies of the large shearwaters that were for a long time included in the genus "Puffinus". Wedge-tailed shearwaters feed pelagically on fish, squid and crustaceans. Their diet is 66% fish, of which the most commonly taken is goatfish. It was thought that the species mostly took food from surface feeding, observations of feeding wedge-tails suggested that
