Prey capture attempts can be detected in Steller sea lions and other marine predators using accelerometers (2010, background): “These acceleration signals appeared to be the main features associated with prey capture events as suggested by Naito (2007) and observed in hooded seals (Suzuki et al. 2009) and harbour seals, Phoca vitulina ( Bowen et al. 2002 ).”
Shallow food for deep divers: Dynamic foraging behavior of male sperm whales in a high latitude habitat (2008, background): “Not knowing the types of prey consumed by the tagged whales, we cannot directly link the whale behavior to a prey type (e.g. Barrett-Lennard et al., 1996; Bowen et al., 2002).”
Selective foraging by fish-eating killer whales Orcinus orca in British Columbia (2006, background): “Prey choice by predators is influenced by rates of encounters with a prey species and its profitability, which is determined by the prey item’s net energy value and the amount of time needed to catch and handle it (Stephens & Krebs 1986, Scheel 1993, Bowen et al. 2002).”
Methods of estimating marine mammal diets: A review of validation experiments and sources of bias and uncertainty (2012, methodology): “Finally, animal-borne video has been used to obtain estimates of the diet of several pinnipeds (Bowen et al. 2002, Madden et al. 2008).”
A comparison of indirect measures of feeding behaviour based on ARGOS tracking data (2007, methodology): “Cameras also have been used to produce direct evidence of feeding (Marshall, 1998; Davis et al., 1999; Bowen et al., 2002).”
Seasonal availability of abundant, energy-rich prey influences the abundance and diet of a marine predator, the Steller sea lion Eumetopias jubatus (2006, background): “Pursuit/handling time for harbor seals was greater for demersal flounder than for schooling sand lance (Bowen et al. 2002).”
Microhabitat use and prey capture of a bottom-feeding top predator, the European shag, shown by camera loggers (2008, background): “…Ser 356: 283–293, 2008 direct qualitative information on biotic and abiotic features of the foraging environment and detailed descriptions of prey capture and interactions with conspecifics and other species (Ponganis et al. 2000, Bowen et al. 2002, Takahashi et al. 2004, Grémillet et al. 2006).”
Comparing individual and spatial influences on foraging behaviour in Antarctic fur seals Arctocephalus gazella (2004, background): “…in diving behaviour of the New Zealand fur seal Arctocephalus forsteri between seasons and years reflected changes in their diet (Harcourt et al. 2002) and foraging tactics of harbour seals differed depending on the behaviour of their prey, both within and between prey species (Bowen et al. 2002).”
Regional, temporal and fine-scale spatial variation in Weddell seal diet at four coastal locations in east Antarctica (2003, background): “Both prey availability and the seals’ functional response (Bowen et al. 2002) determine diet composition.”
Age-related shifts in the diet composition of southern elephant seals expand overall foraging niche (2007, background): “…(Polis 1984) over a range of spatial scales, especially where food resources may be limited due to intra- and interannual variation in productivity (Perry 1996; Kato et al. 2000; Wikelski and Wrege 2000; Bowen et al. 2002), though there have been few detailed studies of larger marine predators.”
Behavioural drivers of the ecological roles and importance of marine mammals (2015, background): “To date, most ecological studies of marine mammals have focused on describing their diets and foraging behaviour (e.g. Bowen et al. 2002, Sargeant et al. 2005) and on how their distributions, abundances and behaviours are affected by both abiotic (physiographic and dynamic oceanographic variables;…”

Harbor Seal Diet in Northern Puget Sound: Implications for the Recovery of Depressed Fish Stocks (2012, background): “Specialized foraging techniques relative to prey type and its behavior are documented for the San Juan Islands, Protection Island, and elsewhere (Suryan & Harvey 1998, Zamon 2001, Bowen et al. 2002).”
