re Dawson, Birds of Okanogan Co., Wash. E75 
which was probably derived from the chips at the bottom of the nest. 
The pitch spots were distributed with tolerable uniformity, and had 
become black through contact with foreign matter. 
53. Sphyrapicus ruber. RED-BREASTED SAPSUCKER.—One specimen 
was shot from a fir tree on the shore of the lake. 
54. Ceophleeus pileatus. PILEATED WooppreckER.—Not common. 
Perhaps a half dozen individuals were seen. 
55. Melanerpes torquatus. Lewis’s WooprrEcKEer.— The ‘Black’ 
Woodpecker is one of the most characteristic birds of the region. It is, 
however, pretty closely confined to the lower levels. Every considerable 
dead tree in the coulées, or along the river banks, is bound to have 
furnished at one time or another a home for these birds. 
56. Colaptescafer. RED-SHAFTED FLICKER.— Common. The careless 
rancher still calls it ‘ Yellow-Hammer ’. 
57- Phalenoptilus nuttallii, Poor-witt.— One specimen secured. 
This bird seems to take its insect prey on or close to the ground. It is 
confined to semi-arid regions in valleys and ‘ draws’. 
58. Chordeiles virginianus henryi. WrsTeERN NIGHTHAWK.— Found 
sparingly in open situations. 
59. Cypseloides niger borealis. BLAck Swirr.— These erratic and 
almost uncanny creatures appeared at Chelan several times during the 
summer of 1895. They would come in a straggling flock at about 
7 o'clock in the morning, hawking at insects as they went, but all coming 
from up the lake and moving eastward. I saw them only once this year, 
on June 9. On this occasion I saw a company of a score hunting leisurely 
at high noon, over the Okanogan River. In the evening of the same day 
a hundred or so gathered after the manner of Chimney Swifts, to gyrate 
in social fashion, at a point on the Columbia River, 20 miles south from 
the first ones observed. 
60. Chetura vauxii. VAux’s Swirt. The only point in the county 
where these birds were noted, was at the head of Lake Chelan, where they 
regularly nested and roosted in the hollow limbs of dead balm trees. 
61. Aéronautes melanoleucus. WHITE-THROATED SwiFt.—A single 
specimen seen while exploring the cliffs of the Columbia River gorge, 
seems referable to this species. It was probably a wanderer from some 
detached colony, recently emigrated to this northern limit of the semi- 
arid region. 
62. Trochilus alexandri. BLACK-cHINNED HuMMINGBIRD.— By no 
means a common bird. Only two glimpses were afforded me of this 
nimble fay, but my conclusions are confirmed by other observers. 
63. Selasphorus rufus. Rurous Hummincpirp.— Abundant. In 
certain mountain glades, where fire-weeds abound, these Hummers fairly 
swarm. They were continually observed in the vicinity of the glacier on 
Wright’s Peak, at an altitude of Sooo feet. In their search for sweets they 
seem to be attracted by color rather than by odor, for they repeatedly 
examined a bright check blanket, which a member of our party had, and 
seemed greatly disappointed that it did not prove to be a flower bed.
