1.Our understanding of the niche concept will remain limited while the quantity and range of different food types eaten remains a dominant proxy for niche breadth, as this does not account for the broad ecological context that governs diet. Linking nutrition, physiology and behaviour are critical to predict the extent to which a species adjusts its...

Sexual segregation in the behaviour, morphology or physiology of breeding seabirds can be related to divergent parental roles, foraging niche partitioning or sex-specific nutritional requirements. Here, we combine GPS tracking, dietary and nutritional analysis to investigate sex-specific foraging of Brown Boobies breeding on Raine Island, Great Bar...

... Several studies on seabirds (Machovsky-Capuska et al., 2018;Machovsky-Capuska and Raubenheimer, 2020), preda-tory fish , turtles (Machovsky-Capuska et al., 2020a;Santos et al., 2020), cetaceans (Denuncio et al., 2017;Machovsky-Capuska and Raubenheimer, 2020;Machovsky-Capuska et al., 2020b), pinnipeds (Machovsky-Capuska and Denuncio et al., 2021), and sharks (Machovsky-Capuska and Grainger et al., 2020), have increasingly applied the MNNF to (i) understand how marine predators adjust their foraging behaviour and nutritional goals to environmental fluctuations (Machovsky-Capuska et al., 2018); (ii) explore the nutritional consequences of consuming plastics and anthropogenic pollutants (Machovsky-Capuska et al., 2019, 2020aSantos et al., 2020Santos et al., , 2021Stockin et al., 2021a, b); and (iii) disentangle the dynamics that facilitates coexistence with other sympatric species (Denuncio et al., 2021), and examine how they are likely to interact with humans (Grainger et al., 2020). ...
... In Abrolhos, estimated population size is about 300 pairs for brown boobies and 200 pairs for red-billed tropicbirds with breeding activity throughout the year (ICMBio, 2019). Foraging areas are located around colonies, but brown boobies tend to explore the immediate colony surroundings (Weimerskirch et al., 2009;Miller et al., 2018a), while tropicbirds tend to travel further and make longer foraging trips (Diop et al., 2018). Both species are primarily plunge divers and feed on fish occurring at the sea surface, but brown boobies can also interact with fisheries and use discards as a food source (Alves et al., 2004;Castillo-Guerrero et al., 2011). ...
