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
Audubon's shearwater likely, as yet another synonym of "dichrous". The case of the more distinct "bannermani", the range of which is parapatric to that of the Pacific "dichrous", is more complicated. It has for some time been proposed as a distinct species, Bannerman's shearwater ("P. bannermani"). In the absence of more recent data to investigate this claim, its status continues to be altogether unresolved, though the case for it being at least a distinct subspecies in the "bailloni" clade seems good. Audubon's shearwater The Audubon's shearwater ("Puffinus lherminieri") is a common tropical seabird in the petrel family. Sometimes known as the dusky-backed
