354 MERRILL, Birds of Fort Sherman, Idaho. ae 
this bird. Cabanis’s Woodpecker is here very unsuspicious, in marked 
contrast to its behavior in some other regions. After the first of March 
they are much less common and they breed but sparingly near the fort. 
Two nests found June 15 contained young, a late date. . 
Dryobates pubescens homorus.— Rather uncommon resident, breeding 
sparingly. Specimens taken here differ from all of the recognized forms 
in some respects. 
Xenopicus albolarvatus.— A rare resident. 
Picoides arcticus.— A fairly common resident, especially on the higher 
parts of the hills, where in winter I have seen many nesting excavations 
undoubtedly made by this bird, which shows a marked partiality for 
locating them near the base of slender pine stubs. Mr. Brewster informs 
me that the bills of specimens taken at Fort Sherman are longer and slen- 
derer than in eastern examples, but less so than in the series I took at 
Fort Klamath, Oregon. 
* Sphyrapicus varius nuchalis.— A few pairs breed among the cotton- 
woods bordering the lake near its outlet and along the river. . 
Ceophleeus pileatus.— A rather common resident, more plentiful in the 
deep woods. 
Melanerpes torquatus.— Arriving early in May, Lewis’s Woodpecker 
soon becomes common and is generally distributed, breeding in cotton- 
woods as well as in pines. d 
Colaptes cafer.— Common summer visitor arriving late in March, 
though a few remain throughout the winter. Breeds from lake level up 
to the summit of Mica Peak. Dr. Allen, in the map accompanying his 
paper on the Flickers,!' places northern Idaho in the habitat of C. auratus 
cafer, or hybridus, as it was formerly called; but all the specimens 
taken at Fort Sherman, both breeding and migrating birds, were pure 
cafer. 
* Chordeiles virginianus.— Arriving about the first of June, few are seen 
until the 12th or 15th, when they suddenly become common, and so remain 
until early in August, when more arrive from the north. They are abun- 
dant until the end of the month, when most leave, a few stragglers being 
seen until the middle of September. 
In regard to some skins collected here Mr. Brewster writes: “This series, 
as a whole, seems to me to be referable to vérgintanus, although two or 
three of the females have too much gray on the back and wings to be 
typical. The male, on the other hand, is atypical vzrg7udanus.” 
* Chetura vauxii.— This Swift arrives early in May and may be seen 
almost daily during the month, generally singly. About July 20 they 
again appear and pass rapidly to the south, though I have seen one as 
late as August 31. While none were observed during the breeding
