Foraging distributions of red-footed boobies and brown boobies according to sex. Kernel density distributions of foraging locations for male and female red-footed boobies (left panel; n bird/trips, female = 5/8, male = 19/46) and brown boobies (right panel; n, female = 27/124, male = 31/93) are shown. Males = orange, Females = green. Distributions are mapped over GEBCO 1 arc-second bathymetry data (source: GEBCO Digital Atlas, Intergovernmental Oceanographic Commission, International Hydrographic Organization and the British Oceanographic Data Centre)
