Note 22 — THE MISSOURI RIVER JOURNALS 1843 (Continued)

Here is the original indication of the curious Flicker of the Upper Missouri region, which Audubon named Picus ayresii, B. of Am. vii., 1844, p. 348, pl. 494, after W. O. Ayres. It is the Colaptes hybridus of Baird, and the C. aurato-mexicanus of Hartlaub; in which the specific characters of the Golden-winged and Red-shafted Flickers are mixed and obscured in every conceivable degree. We presently find Audubon puzzled by the curious birds, whose peculiarities have never been satisfactorily explained.—E. C.
