Pennsylvania Dutch ornamental bird design, from German Distelfink "goldfinch," literally "thistle-finch," from Old High German distilvinko, from distil "thistle" (see thistle) + Old High German finco "finch," from PIE *(s)ping- "sparrow, finch" (see finch). The bird so called because it feeds on thistle seeds. Compare Old French chardonel "goldfinch," from chardon "thistle."
