a) The American mink has been present in Iceland since the 1930’s and despite heavy hunting since 1939 the species has become well established.

c) Direct competition between these species appears to be minimal although the arctic fox will sometimes chase mink and disturb them while foraging.

b) Iceland is therefore an ideal place to study undisturbed feeding behaviour and ecology of mink.
