As will have been gathered from tbe precediug article, the greater 

 l)art of the Missouri region is occui)ied either by the true C. auratus or 

 by the mixed form, the ty[)ical mexivanus being chiefly confined to the 

 western border, aiuong the head-waters of the Missouri and its greater 

 tributaries. 1 did not observe it north of the INIissouri water-shed. Dr. 

 Hayden says that he found it most abundant about the Bad Lands aud 

 the sources of the Missouri. Prof. Baird, however, in 1858, quoted 

 individuals from the Bepublican Fork of the Kansas River, and Prof. 

 Snow speaks of a flock which remained about the timber, near Lawrence, 

 ibr two or three weeks in December. The northernmost record I have 

 seen is Mr. Dall's; he si)eaks of its being taken at Sitka by Bischoff. 

 The true auratus is found in Alaska, north of the main range of mount- 

 ains. In the llocky Mountains the bird becomes fitirly established, 

 mostly freed from admixture with auratus, and occurs tlien(;e, in all 

 suitable regions, to the Pacilic coast. I found it as common in some 

 parts of New Mexico and Arizona as the Flicker is in the East, the 

 habits of the two being identical in all essential resi)ects. In Cohn-ado, 

 says "Sir. Trippe, the si)ecies is common and migratory. '• It breeds 

 from the plains up to timber-line. The Bed-shatted Flicker appears 

 near Idaho Springs about the middle of April, and soon becomes rather 

 common. It is never a very abundant bird, but is to be seen, more or 

 less ire(]uently, throughout the mountains, having very much the same 

 habits as the/ <lolden-winged Woodpecker. It is shy and dillicult of 

 ai»i)roa<;li. In ()ctol)er and November it di.sap])ears, 



''Mrs. .Alaxwell, of Boulder, inlbrnus me that a Yellow-v.inged Flicker 

 has appeared in the groves that fringe the streams near that town, 

 within the last lew year.s, and is gratbudly becoming more abundant. 

 From lu'r de.scri[)tions I should sui)posc it to be C.auratusj but probably 

 it is some form of C. hi/bridus.^^
