- Shark predation and tooth wear in a population of northeastern Pacific killer whales (2011, methodology): “Killer whales will occasionally transport prey for 100 to 200 m while feeding, especially when sharing food with other 218 Ford et al.: Shark predation by killer whales whales (Ford & Ellis 2006).”
- Killer whale (Orcinus orca) interactions with the tuna and swordfish longline fishery off southern and south-eastern Brazil: a comparison with shark interactions (2007, background): “Selective foraging by fish-eating killer whales has been documented in British Columbian waters (Ford & Ellis, 2006).”
- Multilevel Societies of Female Sperm Whales (Physeter macrocephalus) in the Atlantic and Pacific: Why Are They So Different? (2012, background): “Killer whales are very much creatures of habit, with each set of killer whales having a few species of clearly preferred prey, while other potentially nutritious food is ignored (Ford and Ellis 2006; Ford et al. 1998; Pitman and Durban 2011).”
- Cooperative hunting behavior, prey selectivity and prey handling by pack ice killer whales (Orcinus orca), type B, in Antarctic Peninsula waters (2012, background): “…Pacific, “resident” killer whales take mostly chinook salmon (Oncorhynchus tshawytscha) among the six species of salmon available to them, even though it is often one of the least abundant salmon species present (Ford et al. 1998, Ford and Ellis 2006, Ford et al. 2010, Hanson et al. 2010).”
- Estimated field metabolic rates and prey requirements of resident killer whales (2011, methodology): “Third, differences in prey selectivity across pod members of different age and sex classes are not well understood (Ford and Ellis 2006).”
- Swimming speed, respiration rate, and estimated cost of transport in adult killer whales (2009, methodology): “For killer whales, strong sexual dimorphism in body size suggests that there should be considerable inter-sex variability in optimal swimming speed and diving behavior (Baird et al. 2005), foraging ecology (Ford and Ellis 2006), and MR (Kasting et al. 1989, Kriete 1995).”
- The paradox of “premature migration” by adult anadromous salmonid fishes: patterns and hypotheses (2016, background): “Marine mammals (Ford and Ellis 2006) and sharks (Nagasawa 1998; Hulbert et al.”
- Killer whales (Orcinus orca) in the Canadian Arctic: Distribution, prey items, group sizes, and seasonality (2012, background): “Mammal-eating killer whale group sizes theoretically maximize per capita energy intake (Baird and Dill 1996), and in other regions, mean group sizes range from 3.8 individuals for whales feeding on harbor seals and 5.0 individuals for groups foraging on small odontocetes in the northeastern Pacific ”
- Species and stock identification of prey consumed by endangered southern resident killer whales in their summer range (2010, unknown): “Notably absent from the samples were pink salmon, and there were only a few sockeye salmon, confirming Ford & Ellis’ (2006) previous observation that pink and sockeye salmon are not significant sources of prey for the whales, despite the high abundance of these species in the area.”
- Demographic changes in Chinook salmon across the Northeast Pacific Ocean (2018, background): “About 90% of Chinook salmon eaten by residents are 4–6 years old (Ford & Ellis, 2006), and the abundance of resident killer whales has continuously increased since the 1970s (Matkin, Ward Testa, Ellis, & Saulitis, 2014; Ward et al., 2016).”
- Quantifying the effects of prey abundance on killer whale reproduction (2009, background): “The diet of Northern and Southern Resident whales is thought to be dominated by Chinook salmon, which is also the focus of major commercial and recreational fisheries in this region ( Ford & Ellis 2006; Ford, Ellis & Olesiuk 2005).”
- Social network correlates of food availability in an endangered population of killer whales, Orcinus orca (2012, unknown): “…tshawytscha, comprise the largest proportion of their diet during this time, supplemented with chum salmon, Oncorhynchus keta, sockeye salmon, Oncorhynchus nerka, pink salmon, Oncorhynchus gorbuscha, ling cod, Ophiodon elongatus, and Pacific halibut, Hippoglossus stenolepis (Ford & Ellis 2006).”
