Breeding Success of British Kittiwakes Rissa tridactyla in 1986-88: Evidence for Changing Conditions in the Northern North Sea
(1) Data on breeding success from thirty-five British and one Irish kittiwake Rissa tridactyla colony were collected between 1986 and 1988. (2) At each colony the mean number of young fledged per completed nest was similar in 1986 and 1987, but at North Sea colonies success was significantly poorer...
