"The solo of the differs from nearly all other bird-songs that I know, being a clear, distinct whistle that may easily be reduced to our musical scale, and perfectly imitated by the human voice; in this latter quality it is almost unique. The notes are very few, usually two, never, I think, more than three; and the little ditty consists of, first, a single long, deliberate note, then two short repetitious of one a third higher, followed by three triplets at the same pitch. It is so distinct, indeed, that the of northern Minnesota—as a traveler in that country kindly wrote me—have put it into words, namely, "Pu'orn chiman, chig-a-big, chig-a-big, chig-a-big," which being translated means, "The Sioux canoes are close to shore, close to shore, close to shore," and the friendly bird is held in much esteem by the grateful Chippewas."
