AMERICAN THREE-TOEIJ WOODPECKER. 



Picoides americanus Bbehm, llanilbucli der Vogel Deutschlands, 1831, 19.5. 



(B 83, 301, R 368, C 444, U 401.) 



Geographical range : Northeru North America cast of the Rocky Mountains; 

 south (principally in winter) to the northern border of the United States; west, casually, 

 to the western slope of the Bitter Root Mountains, iu eastern Idaho. 



The American Three-toed, also known as the "Banded-backed," "White- 

 backed," or simply as "Banded Tlu-ee-toed" Woodpecker, is mostly resident and 

 lireeds wherever found. Along our northern border it seems to he much rarer 

 tlian the preceding species, and only breeds in small numbers in Maine, the 

 White Mountains in New Hampshire, the Adirondacks in New York, possibly in 

 the Green Mountains in Vermont, and probably along the west shore of Lake 

 Superior in Minnesota; but it is evidently still rarer in the western portions 

 of its range, within the limits of the United States. The only western specimens, 

 taken within our borders, in the United States National Museum collection, are 

 a female, collected by Dr. J. CI. Cooper, on September 9, 1860, on the western 

 slope of the Bitter Root Mountains, Idaho, and a pair sent to me by Mr. R. S. 

 Williams, of Columbia Falls, Montana, taken on October 9 and 11, 1893. He 

 writes me: "It is much rarer here than P. ardicus, and I consider it a much 

 more silent bird,. its ordinary' call notes differing much from those of the former 

 and resembling more those uttered by the genus Bryobates." 



Mr. L. M. Turner met with this Wood2)ecker in the vicinity of Foi-t Chimo, 

 Uiigava, and secured several specimens at Whitefish Lake, Avhere the spnice and 

 junipers attain a slightl}' greater size than nearer the Post. In his manuscript 

 notes he says: "Farther to the southward, where the timber is larger and l)etter 

 suited to their habits, they become correspondingly more numerous, and in 

 southern Labrador, south of the 'Height of Land,' they are reported to be 

 quite plentiful. The manner of flight of this species is less vigorous than 

 tliat of Picoides ardicus, A'et differing iu a maimer that is difficult to describe. 

 These birds are not easy to detect, as they rarely utter a note, and tlien only 

 a s(juealiug, prolonged sound, similar to that made by Spliyrapicus rarius. They 

 are oftener found solitary, rarely two l^eing found in the same patch of wood, 

 excepting in the breeding season, aud later when followed by their young-. 1 

 observed their habit of decorticating large areas of the trunks of trees, very 

 rarely the larger branches, and in (inlx'one instance liavelfound a funnel-shaped 

 hole iu a niucli-decayed snag." 



Stragglers have been taken in winter in ]\lassachusetts and also in AVis- 

 consin, but it does not often find its wa}' so far south. According to Sir Joint
