182 Osgood, New North American Birds. \_k^r\\ 



Remarks. — The Kadiak Winter Wren is merely another illustra- 

 tion of the tendency of west coast birds which range as far north 

 as Kadiak to become pale in their northern habitat. The present 

 form tends in slight degree toward Anorthura alascensis, but not 

 sufficiently to affect its specific rank. Specimens from the Alaska 

 Peninsula would be of great interest but the gap between /ie//eri 

 and alascensis is too great to make the existence of intergradation 

 probable. The type oi pacifica from Simiahmoo, Washington, is 

 in winter plumage and thus quite comparable with fall birds from 

 Kadiak. Its upper parts are almost clear burnt umber, very dif- 

 ferent from the Kadiak birds which are cinnamon brown with a 

 pale filmy wash over it producing an effect somewhat between the 

 cinnamon and broccoli brovi'n of Ridgway. Five specimens of 

 helleri have been examined, three taken in August and two in 

 October. An immature bird from Kadiak is indistinguishable 

 from the same plumage oi pacifica. 



The Kadiak wren is named in honor of Mr. Edmund Heller, 

 my field assistant, to whom much of the success of the past sea- 

 son's work is due. 



Certhia familiaris zelotes,i subsp. nov. Sierra Creeper. 



Type from Battle Creek, Tehama Co., California. No. 170708 U. S. Nat. 

 Museum, ? ad. Collected Oct. 23, 1S98, by R. C. McGregor. 



Distribution. — Southern Cascade Mountains of Oregon and Sierra 

 Nevada of California. 



Characters. — Similar to Certhia f. occidenialishnX. Co\oy& more dusky 

 and less rufescent ; rump decidedly contrasted with rest of upper parts ; 

 similar to Certhia f. montana but much darker; light centers of feathers 

 on head and back much reduced. 



Color. — Top of head and back clove brown or between clove brown 

 and sepia, streaked with creamy white ; rump and upper tail-coverts be- 

 tween chestnut and hazel of Ridgway (in montana the color is cinnamon 

 rufous); wings more nearly black than in any other form, spotted with 

 creamy white; throat nearly pure white; breast slightly creamy; sides, 

 flanks, and crissum lightly washed with fulvous. 



Measurements. — A series of measurements of all the specimens avail- 

 able indicates that of the three western forms occidentalis is slightly the 

 ^ argest with no appreciable difference between montana and zelotes.
