WRENS: Family Troglodytidae 



455] 



DISTRIBUTION. General; Pacific slope from Vancouver Island and southern British 

 Columbia to Oregon. /;; Oregon: Common permanent resident west of Cascades 

 from Columbia River to but not including Curry, Josephine, and Jackson Counties, 

 though it occasionally winters in those counties. (See Figure 16.) 



THE SEATTLE WREN (Plate 79), one of the characteristic birds of the 

 brush patches and woodlands in both the stream bottoms and on the 

 foothill slopes, is the commonest wren in the territory it inhabits and 

 ranks almost with the Song Sparrow in all-year-round abundance and 

 wide dispersion over the occupied territory. It is a comparatively large 

 wren, with energetic mannerisms and a loud, pleasing song, and is the 

 one most frequently found occupying nest boxes about homes. It is a 

 permanent resident in all but the southern counties west of the Cascades 

 but is found there in winter. We have winter birds from Ashland, Med- 

 ford, Gold Hill, Powers, and Gold Beach. The nesting season is largely 

 in May, fresh egg dates extending from April 4 to May 31, the number 

 of eggs varying from three to six. 



This wren was first listed as an Oregon breeding bird from Fort William 

 (Portland) by Nuttall in 1840. Its next appearance in literature is in 

 Anthony's (1886) paper on the birds of Washington County. Since Wood- 

 cock's (1902.) list, a number of publications have referred to it, though 

 for so common a species it has made scant appearance in the ornithological 

 literature of the territory. 



San Joaquin Wren: 



Thryomanes beivicki drymoecus Oberholser
