Biogeographic and phylogenetic sampling of hummingbirds. a Individual collection sites, grouping nearby sites in 5°×5° cells, along with the relative collection site elevation, biodiversity, and type of collected data (morphology, hovering kinematics, or hovering and load lifting kinematics). Colours in pie charts correspond to the colour scheme denoting humming bird clades in b. b All major clades of hummingbirds (defined by McGuire et al.20) were sampled both for kinematic and morphological parameters, though sampling effort varied widely across species and data type
