Best wishes and hope to see you all in Perth, Adam Lammers, M.O., Zeh, J., Pack, A. A., Zang, E. & Lyman, E. (2024). Humpback whale feeding behavior and defecation observed on the Hawaiian breeding grounds. Marine Mammal Science, e13177. https://doi.org/10.1111/mms.13177 Humpback whales and other baleen whales are considered capital breeders, and during migration and breeding, their metabolic needs are thought to be met by breakdown of adipose tissue, resulting in a loss of body mass while migrating thousands of kilometers and engaging in breeding behavior. However, feeding behavior and other evidence of foraging, like defecation and stomach contents of stranded whales, have been observed in winter breeding areas, suggesting that opportunistic feeding may not be uncommon. We report two recent documented instances of humpback whales lunge feeding on schools of fish and on 27 observations of whale defecation in Hawaiian waters during the winter breeding season. These observations raise questions about what prey species whales might be consuming while in Hawaiʻi, where and when they might be foraging, and how important this behavior is for the whales and for Hawaiʻi’s marine ecosystem. -- Adam A.
