A comprehensive study spanning almost five decades has documented significant changes in orca populations within Puget Sound. The findings indicate that endangered southern resident killer whales are spending less time in these inland waters.
In contrast, Bigg's killer whales are increasingly observed in the region, suggesting a shift in habitat use among these species. This trend raises questions about the ecological dynamics at play in Puget Sound.
The dataset serves as a crucial resource for understanding orca behavior and habitat preferences, emphasizing the need for ongoing conservation efforts to protect these marine mammals.
