Glacier Bay, June 27 to July 20, it was seen at all camps, but 
was considered rare. On Chichagof Island, July 20 to 25, a fe- 
male was seen severa! times at Idaho Inlet; and at Port Fred- 
erick, July 29, one was seen. Only females or immatures were 
seen later than June—the males arrive first, and return south 
again early in the summer. Two specimens were taken (Nos. 
331, 332), both females, on Admiralty Island. 
Empidonax difficilis Baird. Western Flycatcher. 
At Windfall Harbor, Admiralty Island, the first western fly- 
catchers were seen, and one secured (No. 339) May 15. At Mole 
Harbor they were occasionally seen and one secured, according 
to Stephens, May 19 to June 10. Dixon heard them commonly 
along Hasselborg River, June 12. At Red Bluff Bay, Baranof 
Island, Stephens collected a male (No. 314) June 14; and at 
Rodman Bay one was seen between August 12 and 20. At Cop- 
permine Cove, Glacier Bay, July 19, Dixon found a nest with 
three fresh eges. The nest was compactly built of moss, and was 
supported against the trunk of a sapling about six feet above 
the ground. Two birds were secured (Nos. 329, 330). Finally, 
Stephens shot an immature (No. 272) at Helm Bay, September 
11, and another was seen there. 
I cannot discover the slightest differences by which to distin- 
cuish the above five birds from a series of EL. difficilis from Cali- 
fornia. 
Cyanocitta stelleri stelleri (Gmelin). Steller Jay. 
Jays were not at all common on Admiralty Island, according 
to Dixon, and the few seen were as a rule very shy. This was 
especially true at Windfall and Mole harbors. At Hasselborg 
Lake one was seen carrying a young varied thrush in its beak, 
and being closely pursued by the irate male thrush. At Kail- 
lisnoo a two-thirds-grown juvenal was taken June 16. At Hawk 
Inlet, August 1 to 9, they were more common and inquisitive, 
as many as a dozen being attracted by a young duck hawk teth- 
ered at camp. 
Stephens records the Steller jay as rare at Red Bluff Bay, 
Baranof Island, in June; three or four were seen at Bear Bay,
