Note 282 — Chapter XX · AUDUBON'S ÆNEID, 1819-1824: WANDERINGS THROUGH THE WEST AND SOUTH
Reading edition
The original of this admirable drawing had been shot at New Madrid, on the Ohio, on November 23, and Audubon, who immediately began to work on it, recorded his conviction that the White-headed or Bald Eagle and the "Brown Eagle," which he later called "The Bird of Washington," were two different species; he thought that the young of the former, which was also brown, was much smaller in size. See Vol. I, p. 241.
