Canna seabird studies 2003 2005
This report covers seabird monitoring work on Canna during 2003. Three visits were made to Canna during 2003 to count and ring seabirds, monitor their breeding success and collect food samples. The timing of the 2003 breeding season was slightly earlier than average for razorbills and European shags. Counts showed that many seabird species are undergoing major declines on Canna. This trend continued in 2003 with European shag, herring gull and mew gull reaching record lows. Common guillemots and both lesser and great black-backed gulls also declined. Northern fulmar numbers showed a slight increase as did black-legged kittiwakes, which reached a new record high. Breeding success was again exceptionally low in European shags, herring and great black-backed gulls, in which mass failures occurred; for northern fulmars and black-legged kittiwakes it was above average.
