Giles, Deborah A.; Teman, Sarah J.; Ellis, Samuel; Ford, John K. B.; Shields, Monika W.; Hanson, M. Bradley; Emmons, Candice K.; Cottrell, Paul E.; Baird, Robin W.; Osborne, Richard W.; Weiss, Michael; Ellifrit, David K.; Olson, Jennifer K.; Towers, Jared R.; Ellis, Graeme; Matkin, Dena; Smith, Courtney E.; Raverty, Stephen A.; Norman, Stephanie A.; Gaydos, Joseph K.
Marine Mammal Science (2023)

Endangered Southern Resident killer whales (Orcinus orca) are fish-eaters that preferentially prey on adult Chinook salmon (Oncorhynchus tshawytscha). Despite being salmon specialists, individuals from all three killer whale pods (J,…
