Canna seabird studies 2001 2002

Abstract

This report covers seabird monitoring work on Canna during 2001. Three visits were made to Canna during 2001 to count and ring seabirds, monitor breeding success and collect food samples. Timing of the breeding season was slightly earlier than average for European shags and later than average for auks. Counts showed small declines, compared with 2000, for black-legged kittiwakes and slight increases for European shags. Major declines affecting Northern fulmars, herring gulls and razorbills continued in 2001, whereas common guillemots continued to increase, reaching a new peak count. Breeding success was exceptionally low for European shags, herring gulls and great black-backed gulls, in which mass failures occurred. Breeding success of black-legged kittiwakes was average and Northern fulmars above average.
