Functional and taxonomic composition of the bird communities in mallee woodlands (n = 64 species) and foothill forests (n = 97 species). Bars show the percentage of species in functional groups based on diet (A), main foraging stratum (B), and nest type (C) and in taxonomic families (D—mallee woodlands, E—foothill forests). Numbers above bars indicate counts of species within groups. Diet groups were based on the main food source following Garnett et al. 2015. If a species uses more than one main food source (e.g., many honeyeaters consume nectar and invertebrates), it was counted in both groups. Foraging location was based on the stratum in which the species forages most of the time. “Open” nests refer to nests constructed outside of hollows or burrows. “Hollow” includes all size classes of hollow
