Short abstract from the book: The arctic skua is a fairly common passage migrant on the
coast from July to November and more rarely in spring and
summer. No arctic skua have been ringed in Denmark, but
seven birds ringed abroad have been recovered in Denmark,
all between August and November. All these birds were ringed
as chicks, three on the Fair Isles, two in Finland and two in
Sweden.
