A fine-scale time budget of Cape gannets provides insights into the foraging strategies of coastal seabirds (2004, background): “There is a tight link between the total duration of foraging trips and the maximum foraging range of individual birds (Hamer et al. 2000; Grémillet et al. 2004).”
Comparison of light- and SST-based geolocation with satellite telemetry in free-ranging albatrosses (2005, background): “2004), and GPS (global positioning system; Weimerskirch et al. 2002; Grémillet et al. 2004).”
Contrasting foraging tactics by northern gannets (Sula bassana) breeding in different oceanographic domains with different prey fields (2007, unknown): “Cape gannets (Sula capensis) at two colonies about 110 km apart oV the coast of South Africa, showed spatial separation in the foraging areas of birds from the diVerent colonies (Grémillet et al. 2004).”
Spatial separation of foraging habitats among New Zealand fur seals (2006, background): “Rapid traversing of nearshore waters is also evident among chick-rearing seabirds (e.g. Gremillet et al. 2004), which implies that these colonial breeding animals cannot rely on nearshore resources, in accordance with the theory of localised depletion (Ashmole 1963, Birt et al. 1987).”
Confusion reigns? A review of marine megafauna interactions with tidal-stream environments (2015, background): “…observation (lateral transfer, e.g. seabirds observing distant flocks of other birds; Grünbaum & Veit 2003), information transfer at colonies (Grémillet et al. 2004, Wakefield et al. 2013, Bogdanova et al. 2014) and/or through teaching specific foraging techniques to offspring (vertical…”
Overlap between vulnerable top predators and fisheries in the Benguela upwelling system: implications for marine protected areas (2009, methodology): “Therefore, their foraging locations were inferred from their GPS tracks based on the path sinuosity, after Grémillet et al. (2004).”
Are seabirds foraging for unpredictable resources (2007, background): “For study sites, reproductive stages, and data available on foraging for seabirds, see Table A1. uctive ST/LTc Data availabled Foraging zone Referencese No R, T, F Shelf Ainley et al. (2003), Irons (1998) No R, T, F Benvenuti et al. (1998) No R, T, F Shelf Hamer et al. (2001) No R, T Up-welling Gré”
Food, fishing and seabirds in the Benguela upwelling system (2007, background): “The decrease of penguins, which have a foraging range of up to about 40 km when breeding (Heath and Randall 1989; Petersen et al. 2006), preceded that of gannets, which are able to forage up to 240 km from colonies (Grémillet et al. 2004).”
Spatial ecology and conservation of seabirds facing global climate change: a review (2009, unknown): “However, similar investigations in the wild indicated that cormorants are capable of maintaining very high predatory performance, even when exploiting fish resources at low density (Grémillet et al. 2004b).”
Spatial interaction between seabirds and prey: review and synthesis (2009, background): “…range of birds from neighboring colonies overlap less than could be expected from the distance between the colonies alone (Ainley et al. 2003, 2004, Grémillet et al. 2004), and the availability of prey around the colony decrease with increasing colony size (Forero et al. 2002, Ainley et al. 2003).”
Perspectives in Ornithology: Application of tracking and data-logging technology in research and conservation of seabirds (2009, unknown): “With GPS, locations can be recorded every second at accuracies within meters of true location, and GPS tags are now relatively inexpensive and small enough (~20 g) to be used on many seabirds (e.g., Weimerskirch et al. 2002a, Grémillet et al. 2004, Hamer et al. 2007, Phalan et al. 2007).”
Quantifying habitat use and preferences of pelagic seabirds using individual movement data: a review (2009, methodology): “A hinterland model has been proposed (Cairns 1989), but this predicts absolute partitioning, whereas tracking data have shown partial partitioning, if any (Stahl & Sagar 2000, Huin 2002, Grémillet et al. 2004).”
