29. Haliaeetus leucocephalus (Linnaeus) Northern Bald Eagle 
Quite numerous along Copper River railway, May 8, where many 
pairs in possession of nest sites — most nests being in black poplars in 
valley. At Eyak lake, Cordova, a pair on ice with a large fish. Eight 
seen in first 10 miles; about twenty seen during day, but few in afternoon 
as birds decreased rapidly inland. All birds noted here adults. 
Not observed on the Chitina. However, on June 13, dilapitated 
remains of an eagle, thought to be a bald, was found in spruce woods near 
camp. The body — that of a juvenile — hanging 10 feet aloft on a spruce 
branch and had hung there since the previous season or longer. Deter- 
mination based mainly on bare tarsus. 
30. Falco rusticolus Linnaeus Gyrfalcon 
Doubtful observation. See under Goshawk. 
31. Falco peregrinus Tunstall Duck Hawk 
Seen but once. While resting in a niche in cliffs, 500 feet above 
timber-line, May 24, a duck hawk sped past on lightning wing heading 
down valley, taking ravines and slopes at a sweep, evidently bent on a far 
destination. 
As party followed down upper waters of Young creek, August 19, a 
nest that had been used earlier in the season was noted in face of a cliff 
rising above stream. Setting exactly that chosen by peregrine. 
32. Falco columbarius Linnaeus Pigeon Hawk 
Observed at Strelna May 8, when train stopped. On the Chitina 
observed first May 30, giving chase to an eagle on swoop, and met again 
June 16, but headquarters of these interesting little falcons not found 
until July 30. On this date, while sheep-hunting above Trail End, a 
family of noisy young that had left nest some days, found holding to last 
woods on that slope of range. Young raised a very constant commotion, 
calling “Killy-kiliy-killy!” in much the manner of young sparrow hawks. 
Daily this family worked farther down valley, reaching near camp 
August 4, when specimens were taken. Next day two seen a mile below 
at Teal pond and from this until mid-August species could be said to be 
fairly common. 
Specimens: Four juveniles, August 4 to 11. 
These birds, though birds of the year, are in complete autumn plumage. Little or no 
variety in them and all characteristically F. c. columbarius. Rather surprising in view of 
fact that those taken by Swarth and Brooks near Atlin, British Columbia, adjacent, are 
F. c. suckleyi , an identification which, having seen the specimens, writer concurs in. Little 
known of distribution of suckleyi and as far as writer knows its nest has never been recog- 
nized unmistakably. In all probability both these Mount Logan birds and those from 
Atlin raised near their respective localities. Yet if suckleyi is a coast breeder how does it 
occur as far inland as Atlin and if it extends as far inland as Atlin why not as far as mount 
Logan ? These are questions that cannot be answered at present or until considerably 
more accurate determination of breeding buds has been made.
