Description:

Approximately half of the North Pacific humpback whale (Megaptera novaeangliae) population migrates from high-latitude feeding grounds to Hawai‘i each winter and spring to breed. Beginning in 2015, fluctuations in whale abundance were reported in Hawai‘i, and this trend has continued in subsequent years. These reports were consistent with passive acoustic monitoring data, which showed a decreasing whale presence off Maui during the same period using male humpback whale chorusing as a proxy for relative whale abundance.
