bunting (n.2) Look up bunting at Dictionary.com
lark-like bird, c.1300, bountyng, of unknown origin. Perhaps from buntin "plump" (compare baby bunting, also Scots buntin "short and thick;" Welsh bontin "rump," and bontinog "big-assed"), or a double diminutive of French bon. Or it might be named in reference to speckled plumage and be from an unrecorded Old English word akin to German bunt "speckled," Dutch bont.
