In the western South Pacific, migratory routes of humpback whales between breeding and feeding areas are unclear. Male humpback whales sing a population-specific song, which can be used to match singers on migration to a breeding population. To investigate migratory routes and breeding area connections, passive acoustic recorders were deployed in the central New Zealand migratory corridor (2016); recorded humpback whale song was compared to song from the closest breeding populations of East Australia and New Caledonia (2015-2017). Singing northbound whales migrated past New Zealand from June to August via the east coast of the South Island and Cook Strait. Few song detections were made along the east coast of the North Island. New Zealand song matched New Caledonia song, suggesting a migratory destination, but connectivity to East Australia could not be ruled out. Two song types were present in New Zealand, illustrating the potential for easterly song transmission from East Australia to New Caledonia in this shared migratory corridor. This study enhances our understanding of western South Pacific humpback whale breeding population connectivity, and provides novel insights into the dynamic transmission of song culture. specialized passive acoustic monitoring cultural transmission humpback whale migration vocal learning NOUVELLE ZELANDE PACIFIQUE SUD 034 7 11 201084 [15 p.] 2020 2054-5703 https://www.documentation.ird.fr/hor/fdi:010080392 2054-5703 [F B010080392] https://www.documentation.ird.fr/hor/fdi:010080392 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers20-12/010080392.pdf IRD - Base Horizon / Pleins textes 2021-01-14 2021-01-14 fdi:010080392 fre
