widgeon (n.)

migratory wild duck, 1510s, perhaps from a northern variant of French vigeon, which some trace to Latin vipionem (nominative vipio), "a kind of small crane," a Balearic word, perhaps imitative, with an evolution of form similar to that which produced pigeon. But the French word is later than the English one, and OED finds all this "very dubious." Applied to different species in Europe and America.
