1910] Grinnell.—Birds: Alaska Expedition, 1908. 413 
one (no. 1355) was taken on Green Island July 15, and three 
full-grown young (nos. 1348-1350) at Hanning Bay, Montague 
Island, July 31. All the specimens are alike, considering age 
and abrasion, and I am unable to distinguish them from N. h. 
pacificus of the Sitkan and Puget Sound regions. Port Nell 
Juan is now the westernmost known station for the species. As 
far as I know the westernmost previous record station is Yakutat 
Bay, 275 miles to the eastward. 
Certhia americana montana Ridgway. Rocky Mountain Creeper. 
Hight specimens secured, nos. 1269 to 1276, from the head of 
Cordova Bay and head of Port Nell Juan, on the mainland, and 
from Hinchinbrook, Montague, Knight, and Chenega islands. 
Although thus widely distributed throughout the region, the 
species is far from common, as only one or two individuals were 
noted which were not collected. Among the latter, two (nos. 
1272, 1273) are full-grown juvenals, both taken on Knight Isl- 
and, August 26. One (no. 1275), from Chenega Island, August 
31, is in complete newly acquired winter plumage. The rest 
are breeding birds with more or less worn plumage. Keeping 
in account the stage of plumage, I find the creepers of Prince 
William Sound, both from the islands and the mainland, uniform 
and indistinguishable from the subspecies montana of the north- 
ern Rocky Mountain region. 
Penthestes atricapillus turneri (Ridgway). Yukon Chickadee. 
Noted only on the mainland, where two specimens were taken 
by Miss Alexander at Valdez, August 29. A small flock was 
seen the next day on the Eagle Government Trail. The speci- 
mens (nos. 1306, 1307) appear to be birds-of-the-year, though 
in nearly full winter plumage. It is probable, considering the 
season, that the observed individuals of this chickadee were fall 
wanderers towards the coast from interior breeding grounds. 
At any rate, the Yukon ehickadee is typically an Alaskan-interior 
species, the Valdez chestnut-sided chickadee replacing it on the 
coast.
