A cockade (a ribbon, badge, or ornament worn on a hat, especially as a military or political symbol).
Variant spelling or pronunciation of 'cockade,' possibly influenced by French 'cocarde.' The term derives from 'cock' (perhaps referring to the resemblance to a rooster's comb) and has been used since the 17th century.
Cockades were so important to military and political identity that they got multiple names—'cockard' is a variant that appeared in different regions and time periods. The rooster connection might be folk etymology, but it stuck!
