Abstract:
Examination of 300 recovery records of Fulmars ringed in Britain allowed the distribution and movements of birds of known age to be described. Biases in the methods of
recovery made estimation of mortality impossible. Soon after fledging, birds disperse
from British waters to the western North Atlantic, Norwegian Sea, and European Arctic
waters. In the fourth year, the distribution contracts, coinciding with the peak return of
pre-breeding birds to land. Adults are restricted to the eastern North Atlantic, North
Sea and European Arctic, moving several hundred kilometres from their colonies at all
seasons.
