Humpback whale song recordings suggest common feeding ground occupation by multiple populations

Abstract Humpback whale males are known to sing on their low-latitude breeding grounds, but it is well established that songs are also commonly produced ‘off-season’ on the feeding grounds or during migration. This opens exciting opportunities to investigate migratory aggregations, study humpback wh...
