Seasonal availability of abundant, energy-rich prey influences the abundance and diet of a marine predator, the Steller sea lion Eumetopias jubatus (2006, background): “…patches are profitable season after season, experience could allow predators to locate prey patches more efficiently in following trips (Miliniski 1994), as marine predators may use a combination of local enhancement and memory to locate prey patches around a central place (Davoren et al. 2003).”
Confusion reigns? A review of marine megafauna interactions with tidal-stream environments (2015, background): “Potential tidally-driven visual cues might include whitecaps, fronts, tidal slicks and other oceanographic features associated with strong currents (Davoren et al. 2003, Tremblay et al. 2014).”
Shoal behaviour and maturity relations of spawning capelin (Mallotus villosus )o ff Newfoundland: demersal spawning and diel vertical movement patterns (2006, methodology): “During research in 2000, we examined the consequences of capelin spawning dynamics on the foraging strategies of large vertebrate predators, primarily seabirds, in the area surrounding the Funk Island Seabird Ecological Reserve (see Davoren et al. 2003a).”
The foraging decisions of a central place foraging seabird in response to fluctuations in local prey conditions (2009, background): “The return directions of flocks are independent of wind direction and velocity below sustained speeds of 25 kmh 1 (Davoren et al., 2003), so we did not include scans when sustained winds were higher than 25 kmh .”
Central-Place Foraging in an Arctic Seabird Provides Evidence for Storer-Ashmole's Halo (2009, background): “Second, intraspecific competition at prey patches close to the colony may decrease foraging efficiency at nearby patches (Davoren et al. 2003b).”
HOW DO MAGELLANIC PENGUINS COPE WITH VARIABILITY IN THEIR ACCESS TO PREY (2005, methodology): “This has been suggested to be the case in Common Murres Uria aalge exploiting spatially predictable prey for a range of up to 100 km (Davoren et al. 2003).”
Seabird foraging behaviour indicates prey type (2008, background): “These birds apparently did not sample their environment but instead use past experience to forage at a location where amphipods or fish doctors were known to be accessible (Davoren et al. 2003).”
Contrasting foraging tactics by northern gannets (Sula bassana) breeding in different oceanographic domains with different prey fields (2007, unknown): “Figure 2 depicts the greater spatial variety of foraging activity at the Bonaventure Island colony compared with Funk Island from which gannets consistently traveled to forage at coastal sites on spawning and postspawning shoals of capelin (Davoren et al. 2003).”
Consequences of foraging trip duration on provisioning behaviour and fledging condition of common murres Uria aalgae (2003, background): “Such a strategy would be effective at Funk Island because an important nursery area for fledgling-adult pairs during the post-fledging period was found close to Funk Island ( 250 km) but far from Great Island ( 600 km; Davoren et al. 2003a).”
