as well as the coast of northern California, I have made com- 
parison. 
One other individual was seen at the same time the above 
was secured, and the two were the only creepers found anywhere 
in the region explored. 
Sitta canadensis Linnaeus. Red-breasted Nuthatch. 
A single specimen of this bird, an adult female (No. 346), 
was secured by Dixon at Windfall Harbor, Admiralty Island, 
April 23. As far as I can discern, this example is identical with 
birds in corresponding plumage from Connecticut. The under 
surface is just as pale as the average in birds from there and 
from California. The species was not common anywhere in the 
region explored, and was found at all in but three places. At 
Windfall Harbor Dixon found a pair prospecting for a nesting 
place in a dead spruce stump, May 4. At Hasselbore Lake a 
pair was seen that was thought to have a nest nearby. And at 
Port Frederick, Chichagof Island, the last of July, one individual 
Was seen. 
Penthestes rufescens rufescens (Townsend). 
Chestnut-sided Chickadee. 
On Admiralty Island Dixon states this chickadee to be *‘scat- 
tered all through the woods; we rarely went all day without 
seeing or hearing one.’’ At Windfall Harbor a pair were build- 
ing their nest May 15, and on May 10 Stephens saw a chickadee 
‘‘earrying an insect in its mouth, as if to young.’’ At Mole 
Harbor and the lakes in the vicinity the species was seen occa- 
sionally, as also at Killisnoo. 
On Baranof Island, at Red Bluff Bay, June 11 to 20, it was 
not common. Several were seen, and on various oc@easions, at 
Port Frederick, Chichagof Island, the last week in July. On 
Glacier Bay Dixon saw a small flock July 16 at Coppermine 
Cove, and at Helm Bay Stephens saw one flock September 10. 
The seven chestnut-sided chickadees secured by the expedition 
(Nos. 347-350, 315, 356, 273) are typical of the species. In fall 
plumage the back and sides are darker, more of a sooty burnt 
umber, than in the year-old summer plumage where tbey are 
hazel. The pileum, too, is darker—histre instead of sepia,
