Author Contributions

TA and his laboratory organized and carried out the radar field work. MR extracted and prepared the final dataset and performed the scaling analyses. JB organized the tracking information into a database, including information about biometry. PGPE constructed the phylogenetic tree and classified the species into main phylogenetic groups, and OH performed the scaling analyses based on phylogenetic contrast data. TA, MR, JB, PGPE, and OH participated in the evaluation and discussion of results and writing of manuscript.
