TROGLODYTES TROGLODYTES HELLERI (Osgood) 

 KODIAK WREN 



This race seems to be confined to Kodiak Island. Dr. Wilfred H. 

 Osgood (1901) named it in honor of Edmund Heller, who was with 

 him when the type was collected. He described it as "slightly larger 

 and paler colored than" the western winter wren, and remarked that 

 it "is merely another illustration of the tendency of west coast birds 

 which range as far north as Kodiak to become pale in their northern 

 habitat." 



Dr. Oberholser (1919) calls it similar to the Unalaska bird, "but 

 smaller, especially the bill; upper surface much darker, more sooty 

 (less rufescent) ; dark bars of lower back, rump, and upper tail-coverts 

 more conspicuous; lower parts darker, and posteriorly more heavily 

 dark-barred." 



It is apparently one of the rarest of the subspecies, and very little 

 seems to be known about it. 



TROGLODYTES TROGLODYTES STEVENSONI Oberholser 

 STEVENSON'S WINTER WREN 



Dr. Harry C. Oberholser (1930) has split off another finely drawn 

 race from the many recognized subspecies of Alaskan wrens, to which 

 he has given the above name. He describes it as similar to the Una- 

 laska wren, "but upper parts, and to a less extent, also the lower sur- 

 face, more grayish or sooty (less rufescent) in both adult and juvenal 

 plumages ; posterior lower parts in adult on the average less heavily 

 spotted with fuscous ; bill and middle toe averaging slightly longer." 



He says that it is found on "Amak Island and Amagat Island, 

 Alaska ; and probably also other neighboring islands and the south- 

 western end of the Alaska Peninsula. 



"As in most of the other Alaska races of this species there is con- 

 siderable individual variation in this new form; and the differences, 

 while very readily recognizable in a series, are, of course, to some ex- 

 tent overlapped by individuals of the most closely related subspecies, 

 Nannus troglodytes petrophilus. It is interesting, however, to note 

 that the color differences are fully as noticeable in the juvenal plumage 

 as in the adult, as is well shown by the series of 10 young and 5 adults 

 from Amak and Amagat Islands that have been examined."
