unwary. When the young are nearly full grown, the flock begins to retire 
slowly up the mountain side until the middle of fall, when they are to be 
-found only on the higher ridges. Those, however, whose winter home is 
on the highest western ranges do not seem to have so much latitude of 
movement. On August 5 I encountered a brood ot full grown young on 
Wright’s Peak, at an altitude of 7000 feet. 
29. Dendragapus franklinii. FRANKLIN’s GRouUSE.—Not nearly so 
common a bird as the last. It does not apparently range so low as the 
Sooty Grouse in any given section where both are found; nor on the 
contrary, I suspect, is it to be found about the higher peaks. On the 28th 
of April, 1896, I found a nest of this bird at an altitude of about a 
thousand feet above Lake Chelan. The bird was a close sitter, and her 
seven eggs were unusually large: 1.98 by 1.83 and 1.94 by 1.35, being the 
measurements of two average eggs of the set. 
30. Bonasa umbellus togata. CANADIAN RUFFED GrRousE.— The 
differentiation of the subspecies of the Ruffed Grouse is not at all clear 
in this region. In any case the range and habit of the local species is 
nearly like that ot the eastern bird, inasmuch as it frequents copses, 
springs, and river-bottoms at low altitudes. 
31. Lagopus leucurus. WHITE-TAILED PTARMIGAN.— This species is 
reported as not uncommon in the higher altitude. I met with them once 
on the barren summit of Wright’s Peak, at an elevation of about gooo feet. 
So far from deserving the name of ‘fool hens’, applied to them in the 
winter season, when they may be readily approached, these Ptarmigan in 
August were excessively afraid and absolutely unapproachable, although 
it is certain they had never seen a human being before. 
32. Pediocetes phasianellus columbianus. CoLUMBIAN SHARP- 
TAILED GRousE.— The common bird in open situations, which yet afford 
copses and cover,— an invariable accompaniment of stubble-fields, and an 
habitué of grain-stacks. In portions of the county they are still very 
abundant, but where hunted they soon become extremely wary. 
33. Zenaidura macroura. MourRNING Dove.—Not at all common. 
Only one nest was found:during my stay. 
34. Cathartes aura. TuRKEY VULTURE.—A scattering few are to be 
found, but it is doubtful whether the county boasts a score. 
35. Circus hudsonius. Marsa Hawxk.— Perhaps a dozen individuals 
seen. 
36. Accipiter velox. SHARP-SHINNED HAWK. Several individuals noted. 
37- Buteo borealis calurus. WESTERN RED-TAIL.— Based on a single 
specimen, preserved by Ralph Metcalf, near Silver. The Buteos are rare 
in Okanogan County, but must be common on the Big Bend Plateau, just 
across the Columbia River. 
38. Archibuteo lagopus sancti-johannis. AMERICAN ROUGH-LEGGED 
Hawk.— Only one individual of this cumbrous Hawk was noted. 
39. Archibuteo ferrugineus. FERRUGINOUS ROUGH-LEG.— Several 
pairs seen. I found a nest near Chelan, which was occupied by two fresh
