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
Chagos Archipelago fuscata"), brown and lesser noddies ("Anous stolidus" and "Anous tenuirostris") wedge-tailed shearwaters ("Puffinus pacificus") and red-footed boobies ("Sula sula"). Land bird fauna is poor and consists of introduced species and recent natural colonisers. Red fody had been introduced and now widespread. Environments of Chagos Archipelago provides rich biodiversity and support varieties of cetacean species within the vicinity, such as three populations of blue whales and toothed whales (sperm, pilot, orca, pseudo-orca, risso's and other dolphins such as spinners, and so on). Dugongs, being locally extinct today, once thrived in the archipelago and the Sea Cow Island was named after the
