Contrasting foraging tactics by northern gannets (Sula bassana) breeding in different oceanographic domains with different prey fields (2007, unknown): “Colonies occupied by the same species may vary in their prey Welds, mostly as a function of biogeographic zones, topographic location (oVshore/inshore) and hydrographic characteristics (e.g. Hamer et al. 2001).”
Foraging behaviour and energetics of Cape gannets Morus capensis feeding on live prey and fishery discards in the Benguela upwelling system (2007, result): “The lack of a significant regression between foraging path length and foraging trip duration among Bird Island birds is unique compared to results found for other colonies of Cape and Northern gannets (Hamer et al. 2001, Lewis et al. 2006).”

SUMMER DISTRIBUTION AND MIGRATION OF NONBREEDING ALBATROSSES: INDIVIDUAL CONSISTENCIES AND IMPLICATIONS FOR CONSERVATION (2005, background): “…all of the reproductive cycle (Weimerskirch et al. 1993, Phillips et al. 2004b) although again, this is not universal (Hedd et al. 2001); in some species, consistent individual preferences for specific foraging areas or departure directions (Weimerskirch et al. 1993, Irons 1998, Hamer et al. 2001).”
Short-term effects of data-loggers on Cory’s shearwater (Calonectris diomedea) (2005, background): “…of the bird, are used to automatically record location and activity or to monitor environmental variables such as water temperature, salinity and sea currents (Wilson et al. 1995, 1997, 2002; Tuck et al. 1999; Garthe et al. 1999; González-Solis et al. 2000; Hamer et al. 2001; Hedd et al. 2001).”
Loyalty pays: potential life history consequences of fidelity to marine foraging regions by southern elephant seals (2004, background): “Many vertebrate species living in seasonally fluctuating environments demonstrate impressive migrations and long-term fidelity to foraging or breeding regions (Stewart & DeLong 1995; Block et al. 2001; Hamer et al. 2001; Lohmann et al. 2001).”
Annual variation in diets, feeding locations and foraging behaviour of gannets in the North Sea: flexibility, consistency and constraint (2007, methodology): “…with the notion that birds employed a form of network foraging (Clode 1993, Jaquemet et al. 2005) in which they set out on a bearing to a known feeding site and continued until they either located prey for themselves or encountered other birds flying towards a feeding flock Hamer et al. 2001).”
Sex-specific foraging behaviour in tropical boobies: does size matter? (2005, background): “Hamer et al. (2000, 2001) have demonstrated a linear relationship between foraging trip duration and foraging range in the closely related Northern Gannet.”
Offshore diplomacy, or how seabirds mitigate intra-specific competition: a case study based on GPS tracking of Cape gannets from neighbouring colonies (2004, background): “Relatively good feeding conditions for birds from Malgas are also underlined when comparing our results with those of recent investigations in northern gannets from the British Isles (Hamer et al. 2000, 2001).”
Foraging strategies of the black-legged kittiwake Rissa tridactyla at a North Sea colony: evidence for a maximum foraging range (2002, background): “Recent work on Northern gannets Morus bassanus in the North Sea has shown a very strong relationship between range and trip duration (Hamer et al. 2000, 2001).”
Inter-colony movements, at-sea behaviour and foraging in an immature seabird: results from GPS-PPT tracking, radio-tracking and stable isotope analysis (2011, background): “... immature gannets caught on Grassholm in 2009 travelled extensively throughout the Irish Sea, Celtic Sea, NE Atlantic and the Bay of Biscay, moving much greater distances compared with breeders tracked from the same colony during 2006 (Fig. 1).
