Singing Whales

According to Ellen Garland from the University of St Andrews, we can tell where a humpback whale has travelled from the themes in its song. She and her team recorded 52 whales at locations across the south Pacific. They found three song types that were dominant in different regions, and the whales seemed to have picked up bits of songs from other whales along popular migratory routes.

The team broke down each song into units, like notes, that build together to make a phrase, and several phrases that repeat to form a theme. A few themes are sung in a set order to form a song. They found three song types from 52 whale singers. Song type 1 was dominant in the central Pacific, including the Cook Islands and French Polynesia. Song type 2 was most common in the west, including New Caledonia, Tonga and Niue. And song type 3 was only recorded in the waters near eastern Australia.
