Etymology
The word bustard comes from the Old French bistarda and some other languages: abetarda (pt), abetarda (gl), avutarda (es) used for the great bustard. The naturalist William Turner listed the English spelling "bustard" and "bistard" in 1544.
All of the common names above are derived from Latin avis tarda or aves tardas given by Pliny the Elder, these names were mentioned by the Pierre Belon in 1555 and Ulisse Aldrovandi in 1600. The word tarda comes from tardus in Latin meaning "slow" and "deliberate", which is apt to describe the typical walking style of the species.
