Fin whales are highly migratory.
The whales move to high latitude feeding grounds during spring and summer and return to southerly, temperate waters for mating and calving during autumn and winter. As with other migratory baleen whales, northern and southern hemisphere populations do not interbreed due to asynchronous seasons. Fin whales feed mainly on krill but also eat schooling fish including herring, cod, mackerel, pollock, sardine, and capelin. Fish are eaten more often in winter. Mating and calving occur from November to March in temperate waters.
