Alongside the mute swan (Cygnus olor), Dalmatian pelican (Pelecanus crispus), kori bustard (Ardeotis kori), and Andean condor (Vultur gryphus), it is one of a handful to weigh in excess of 10 kilograms between the sexes, and one survey of wintering trumpeters found it averaged second only to the condor in mean mass.
