BOU 1915, has, “from its peculiar wing-markings.” Gruson 1972, says the epithet refers to the discordant flight-note, but the original description is based on Catesby, where no reference is made to the bird’s habits or calls (Spatula).
● "QUA BIRD, OR AMERICAN NIGHT HERON.  (Ardea discors, A. nycticorax, WILSON  ...  at intervals they utter a sort of recognition call, like the guttural sound of the syllable 'kwàh, uttered in so hollow and sepulchral a tone, as almost to resemble the retchings of a vomiting person."
