Woodpeckers were uncommon in the Prince William Sound 
region. The only ones secured by the 1908 Expedition were the 
two constituting the main basis of the above description. Both 
were taken by Heller, no. 1288 (the type) in some alders on an 
islet at Valdez Narrows, September 18; and no. 1287 on Naked 
Island, September 7. Woodpeckers, probably of this species, 
were heard by the same collector, on Dise Island, Chenega Island, 
Knight Island, and Hawkins Island. 
Selasphorus rufus (Gmelin). Rufous Hummingbird. 
Although at practically the northern extreme of its range, 
the rufous hummingbird proved to be well represented in the 
Prince William Sound region. Those seen at the head of Cor- 
dova Bay were slightly above 61° N. latitude. Miss Alexander 
secured an adult male (no. 1262) at Cordova June 6; and an 
adult female (no. 1263) at Canoe Passage, Hawkins Island, June 
20. These were the only specimens actually captured; but the 
species was observed many times also on Hinchinbrook and 
Montague islands. Near Zaikof Bay, on the latter island, Dixon 
records that a rufous hummer appeared at 1600 feet altitude 
over a waste of snow-slides, and buzzed up within a few feet 
of him. Heller notes that no hummingbirds were seen feeding 
around flowers. None were seen anywhere after the last week 
of July. 
Empidonax trailli alnorum Brewster. Alder Flycatcher. 
Detected but onee, on June 10, when Dixon shot an adult 
male (no. 1248) in an alder thicket at the head of Cordova Bay. 
This specimen is very clearly alnorum. As compared with ex-
