Note 106 — Chapter XXIX · SIDELIGHTS ON AUDUBON AND HIS CONTEMPORARIES

See Ornithological Biography, vol. v, p. 194; and Theodore Gill (Bibl. No. 206), The Osprey, vol. iv and v. It seems that Dr. James Trudeau, out of ignorance or disregard for Swainson's designation, later named a woodpecker, obtained near New Orleans in 1837, Picus auduboni, and by a strange coincidence, as Dr. Gill has noticed, the same name was given by two different naturalists to the same bird, now regarded as a variety and known as Dryobates villosus auduboni.
