CREEPERS: Family Certbiidae 



[447] 



have only one winter skin from outside of the regular range. This was 

 taken at Ontario, January 4, 19x7, by Jewett. The bird is neither common 

 nor conspicuous consequently, it is overlooked by many observers. We 

 have found it sparingly throughout the year in the above localities, but 

 its insignificant notes and brown-streaked dress render it difficult to find, 

 even when present. 



We have only one nesting record. Jewett located a nest near Lick Creek, 

 July 17, 19x6, having been attracted to it by noticing the female come 

 from behind a slab of loose lodgepole bark. The nest was about 8 feet 

 from the ground and contained five newly hatched young.

DESCRIPTION. "Upper parts dusky anteriorly, becoming bright rusty on rump; 

 superciliary, streaks on scapulars, and spots on primaries white; throat and breast 

 pure white, sides and flanks tinged with brownish." (Bailey) Si%c: Length (skins)

DISTRIBUTION. General: Breeds in Cascade Mountains of Washington and Oregon 

 and Sierra Nevadas of California, spreading to adjacent valleys in winter. In Oregon: 

 Breeds along summit and eastern slope of Cascades and through timbered parts of 

 Klamath and Lake Counties. Winters throughout much of its range. (See Figure 



OUR KNOWLEDGE of the range of the various forms of creepers both in 

 summer and winter is still far from complete. They seem to be some- 

 what more abundant in the territory normally occupied by this race, the 

 Sierra Creeper, or at any rate we have more specimens of this form with 

 which to work. All our specimens from the summit of the Cascades east 

 to Tumalo, Bend, Cougar Peak, and Lakeview and west to the head of
