598 THE FAUNA OF MONTANA TERRITORY. 
Wooprecker (P. Gairdneri) were seen abundantly from the 
eastern base of the mountains westward. 
WHITE-HEADED WOODPECKER (Picus albolarvatus). First 
met with by me, as in 1853, at the: Spokan. river, September 
24; and at Fort Colville, a week later, I saw several. They 
were very shy,and made a shrill note of alarm, much like that 
of some squirrels, for which I at first looked out on hearing 
it. At Fort Dalles, I found a family of them associating near 
the quarters, and quite tame, so that I obtained three fine 
specimens. They prefer open pine woods, and seek for food 
chiefly in. the bark of the Yellow-pine (Pinus ponderosa), the 
prevailing tree in the above localities. In. notes ‘and habits 
they most resemble the small Sap-suckers, and associate 
with them. 
Arctic WoopPEcKER (Picoides arcticus). -I first met with 
the large Three-toed Woodpecker, at the crossing of the 
Bitterroot, September 6th, where the open woods, before 
traversed, were exchanged for a very dense growth, with 
several kinds of common spruce, which had not been before 
seen. In these dark forests I found this and the striped 
species (P. dorsalis) the commonest woodpeckers, but also 
saw many of this kind afterwards in the more open pime 
forests between. Spokan river and Fort Colville, where I 
also saw them in October, 1853. 
brown; bill, slaty black; feet, gray in both. I saw this spe- 
cies but once besides, at the west base of the same moun- 
tains. At each time I found it very silent ( 
by its. tapping on the trees), quite fearless, 
ing only the low, generally fallen trunks, in the most aar 
part of the forest. I had, of course, little opportunity m 
notice its habits farther than this, All seen were: at an
