Humpback whales, once nearly driven to extinction by commercial whaling, have shown remarkable recovery in the South Pacific. Recent research published in Current Biology reveals that older males are now dominating reproductive success. This study, based on nearly two decades of data from New Caledonia, indicates that as whale populations have rebounded, the age structure has shifted, allowing older males to gain a reproductive advantage. They engage in more mating behaviors, such as singing and escorting females, leading to increased offspring production compared to younger males. This phenomenon suggests that experience and advanced singing abilities may play crucial roles in attracting mates. The research highlights the enduring legacy of industrial whaling, showing that human impacts can alter species behavior and population structure for generations. Lead author Dr. Franca Eichenberger emphasizes the importance of long-term data collection, as it provides insights into how species recover from extensive human interference.
