The black-legged kittiwake (Rissa tridactyla<\/em>) obtains its food from the sea surface and hence functions as an indicator for this part of the marine ecosystem. This pelagic gull constitutes a large proportion of the seabirds, both in terms of biomass and food consumption, and is widespread across Svalbard and the rest of the Arctic.<\/p>\n\n\n\n
