The four species largely differed in their feather isotope values. In agreement with their known habitat preferences, stable carbon isotopes showed that the frugivore and the nectarivore relied mostly on C3 plant dietary sources, whereas both the granivore and the insectivore depended on diet originating from a higher proportion of C4 plant-based food. Stable nitrogen isotopes confirmed the expected trophic positions of the four species. Both stable isotope tracers suggested that the granivore occupies a considerably wide isotopic niche relative to the other species.
