Aging Atlantic puffins Fratercula arctica in summer and winter.
Seabird, 27.
22-40.
Abstract
Atlantic puffins Fratercula arctica in summer and winter plumage can be aged as
first-year, second-year, third-year, young adult and old adult using the number of
grooves on the outer part of the beak. The technique is useful to bird ringers and
those dealing with birds found dead in wrecks and pollution incidents where
knowledge of the ages of individuals involved can help assess the likely effect on
breeding populations.
