The common eland appears to use a peculiar combination of sight and sound – in the form of a conspicuous carpal bar and loud clicking from the carpal joint – to keep contact within the herd. The khur and other Asian wild asses have a similar marking in the form of a conspicuous chestnut, which suggests that they too may be tuned in to a joint-click, but one falling below the limits of human hearing.
