Back in Pre-Revolutionary America when the song ‘Yankee Doodle’ was first popular, the singer was not referring to the pasta ‘macaroni’ in the line that reads ‘stuck a feather in his hat and called it macaroni.’ ‘Macaroni’ was a fancy (‘dandy’) style of Italian dress widely imitated in England at the time.
Birds depend less on the senses of smell and taste than people do. Most birds have little use for the sense of smell. The odors of food, prey, enemies or mates quickly disperse in the wind. Birds possess olfactory glands, but they’re not well developed in most species, including the songbirds in our backyards.
