Abbreviations: ID#, bat identification number; m, body mass for each experiment; R, wing length; AR, wing aspect ratio; p_w, wing loading; ρ_f, air density at failure; estimated as the average of the last flight-capable air density and the subsequent air density at which hovering was unsuccessful); t,mean hovering duration at the last flight-capable air density.
