Violin plots of bird body mass, organised by more inclusive diets and the whole range of diets considered. A, B Bird masses grouped by broad categories of diet, “inclusive diet”, excluding (A) and including (B) semi-specialists. C, D Bird masses grouped by the main diet categories in this paper, excluding (C) and including (D) semi-specialists. In C, FrugivoreH is represented by a single taxon, thus is a point. Dromaius novaehollandiae is excluded from all graphs as an outlier. Inclusive diets with the same letters above them do not have significantly different average masses in phylogenetic HSD at the p = 0.05 level (Table 2). Diet abbreviations: FrugivoreH hard frugivore, FrugivoreS soft frugivore, GranivoreS swallowing granivore, GranivoreH husking granivore, InvertivoreH hard invertivore, InvertivoreM medium invertivore, InvertivoreS soft invertivore, Tetra Hunt tetrapod hunter
