north; hole for nest very smooth, almost polished; eggs four to six, small, clear white. 

 I find, almost always, in the winter and spring, the grub of the large headed borer of the 

 buprestid beetle, Chrysobothrys femorata, in the stomach of this species. This bird 

 feeds largely on the larva? and pupa? of the coddling moth and our numerous leaf 

 rollers. This and the preceding species are much the same, except for size.

1 78-4OO-(-lr4;5). Picoides arcticus (Swains.). ARCTIC THBKE-TOED WOODPECKER; 



BLACK-BACKED THREE-TOED WOODPECKER. 



Very rare south: abundant near Higgins Lake and north; " not seen at Ann Arbor" 

 (Dr. J. B. Steere); "have seen twenty in one trip through the woods at Howard City 

 and Cadillac" (Dr. M. Gibbs); "found common in pineries by N. A. Eddy (O. and O., 

 Vol. VII. p. 143); "I have no account of it south of Ionia County; * taken not uncom- 

 monly in Grand Traverse and Roscommon Counties'' J. C. Nichols); "common in the 

 Gogebic region" (H. Nehrling); embraced in Cabot's Birds of Lake Superior; " not rare 

 on Upper Peninsula'' (A. N. Wood in O. and O., Vol. IX, 1884, p. 62); " Keweenaw Point" 

 (Kneeland); "common in North Michigan pineries" (Prof. Ludwig Kumlein); "common 

 in Iron County" (S. E. White); "not rare in Grand Traverse County "(M. L. Leach); 

 common on Saginaw Bay (N. A. Eddy in O. and O., Vol. IX, p, 5); one in collection 

 of Dr. E. S. Holmes, Grand Rapids, was taken in Kent County, and one in the fine 

 collection of Levi Broas, Belding, was taken in Ionia County. Without doubt this bird 

 breeds in the northern partof this state; " I know of one instance of its breeding in 

 Roscommon County" (Dr. W. C. Brownell); Mr. E. E. Brewster writes me that this bird 

 is common in winter at Iron Mountain, but he cannot say that it breeds.
