Individual dietary specialization and dive behaviour in the California sea otter: Using archival time–depth data to detect alternative foraging strategies (2007, methodology): “We also systematically collected observational foraging data from study animals using standard protocols (Ralls et al., 1995; Watt et al., 2000; Estes et al., 2003); a full analysis of these observational data is presented elsewhere (Tinker, 2004; Tinker et al.”
The Structure of Ecological Networks Across Levels of Organization (2020, background): “…most of the classic empirical examples of keystone species shaping ecological communities due to indirect effects show species with either (a) generalist diets or (b) generalism at the species level emerging due to intrapopulation variation in traits or preferences (Estes et al. 2003, Paine 1966).”
Tools for quantifying isotopic niche space and dietary variation at the individual and population level (2012, unknown): “A finding of low similarity would provide evidence for among-individual variation, or individual diet specialization (sensu Bolnick et al. 2003; Estes et al. 2003).”
Multiple foraging strategies in a marine apex predator, the Galapagos sea lion Zalophus wollebaeki (2008, background): “Ecological prerequisites of foraging specializations stated by Estes et al. (2003) include weak interspecific competition coupled with strong intraspecific competition for limited resources.”
Variation in δ13C and δ15N diet–vibrissae trophic discrimination factors in a wild population of California sea otters (2010, methodology): “The data from this bounded period defined a foraging ‘‘bout’’ (Estes et al. 2003, Tinker et al. 2008).”
FORAGING DEPTHS OF SEA OTTERS AND IMPLICATIONS TO COASTAL MARINE COMMUNITIES (2004, result): “Our finding of differences in foraging depths among individuals is consistent with individual-based preferences in foraging strategy related to diet recently described in sea otters (Estes et al. 2003).”
Developmental evidence for foraging traditions in wild bottlenose dolphins (2009, background): “Publishe Giraldeau 2001; Laland 2004), and is considered to be a critical underpinning of complex cognition, behavioural flexibility and individual differences (e.g. Estes et al. 2003; Whiten & van Schaik 2007).”
Individual hunting behaviour and prey specialisation in the house cat Felis catus: Implications for conservation and management (2015, background): “Recent studies have uncovered between-phenotype foraging specialisations in populations of sea otters (Estes et al., 2003), guillemots (Woo et al.”
Diversity in trophic interactions of green sea turtles Chelonia mydas on a relatively pristine coastal foraging ground (2011, unknown): “…be considerable and consistent variation in behaviors and diets among individuals of a population, including those of the same age/sex class (e.g. Estes et al. 2003, Bearhop et al. 2004, Svanback & Bolnick 2005, 2007, Vander Zanden et al. 2010, Matich et al. 2011; see Bolnick et al. 2003 for a…”
Movements, habitat use and feeding success of cultural clans of South Pacific sperm whales (2004, background): “That this does not happen in any substantial fashion may reflect ‘cultural inertia’, as discussed by Estes et al . (2003) with reference to sea otters ( Enhydra lutris ). Like other apex predators in which intraspecific competition is the primary determinant of fitness, sperm whales probably benef”
Multilevel Societies of Female Sperm Whales (Physeter macrocephalus) in the Atlantic and Pacific: Why Are They So Different? (2012, background): “…if there are consistently two or more rather different types of prey available, and specialization generally pays, then culturally propagated feeding traditions, which expand into other areas of behavior, may evolve in communities of interacting animals (Estes et al. 2003; Sargeant and Mann 2009).”

Prey selection by resident common bottlenose dolphins (tursiops truncatus) in Sarasota Bay, Florida (2010, background): “The extent to which individual prey selection in dolphins occurs is unknown; however, variation in foraging specialization among individuals has been shown in other species, such as sea otters Enhydra lutris, where individual dietary patterns were determined to be life-long characteristics that are ”
