Northern hemisphere population migrates yearly between equatorial regions (e.g. Azores) and the Barents Sea. They arrive at the coast of northern Norway in June-July and leave after the herring feast in February. In the Vestfjord, fin whales are seen during the months June-September either solitary, mother calf pairs or in groups of more than 15 individuals.
Fin Whale Sounds
NOTE ** Fin whale sounds are around 20 Hz and so loud they can be heard over 1000km in the Ocean. However, because of the very low frequency, you will need headphones or loudspeakers to hear the hums. Have fun!
