  abstract = {{W}hile interspecific differences in foraging behaviour have attracted much attention, less is known about how foraging behaviour differs between populations of the same species. {H}ere we compared the foraging strategy of a pantropical seabird, the red-footed booby {S}ula sula, in 5 populations breeding in contrasted environmental conditions. {T}he foraging strategy strongly differed between sites, from strictly diurnal short trips in {E}uropa {I}sland ({M}ozambique channel) to long trips including up to 5 nights at sea in {G}enovesa {I}sland ({G}alapagos archipelago). {T}he {E}xpectation {M}aximisation binary {C}lustering ({EM}b{C}) algorithm was used to determine the different behaviours of individuals during their foraging trips (travelling, intensive foraging, resting and relocating). {D}uring the day, the activity budget was similar for all the breeding colonies. {D}uring the night, birds were primarily on the water, drifting with currents. {A}t all sites, birds similarly performed intensive foraging in zones of area-restricted search ({ARS}), although the size and duration of {ARS} zones differed markedly. {R}ed-footed boobies foraged over deep oceanic waters, with chlorophyll a concentrations varying between sites. {B}irds did not appear to target areas with higher productivity. {W}e suggest that range differences between populations may be linked to other factors such as intra-and interspecific competition.},
