bers than others. During August, 1912, I noted the birds frequently and secured 
specimens, but during the same season the following year, they were very scarce, 
only one or two being seen. 
Buteo borealis alascensis. Alaska Red-tail. Seen occasionally from the coast 
up to 4000 feet in the mountains. A specimen taken in the mountains of Baranof 
Island, August 28, 1912, was gorged with a small rodent (Microtus) , while an- 
other taken on Kruzof Island, August 26, 1913, contained the remains of grouse. 
This hawk was most plentiful near the upper edge of the timber and was fre- 
quently seen hunting above timber line. Bean (1882, p. 162) records a specimen 
taken near Sitka June 5, 1880. J. Dixon took a specimen at Port Frederick, 
Chichagof Island, July 28, 1907 (Grinnell, 1909, p. 21 1). 
Archibuteo lagopus sancti-johannis. Rough-legged Hawk. Taken at Sitka 
by Bischoff (Dali and Bannister, 1869, p. 272). 
Haliaeetus leucocephalus alascanus. Northern Bald Eagle. The most com- 
mon raptorial bird of the region, occurring from the ocean to the tops of the 
mountains. The nest is always placed near salt water, all those noted being in 
tall coniferous trees. The birds seen in the high mountains during the summer 
were nearly all immature. The young leave the nest late in August. According 
to Brightman, the eggs are deposited in late April and early May. 
During the early summer months these birds apparently subsist to a consid- 
erable extent on fawns. Several dead eagles examined at this season were gorged 
with fawn meat, and the claws were covered with hair. The hunters of the re- 
gion claim that the eagle is the worst enemy the deer have, and kill them at every 
opportunity. In the early fall when the salmon are running up the streams to 
spawn, these birds feed largely on fish, and they may be seen in numbers around 
every salmon stream. A nest examined on St. Lazaria Island in August, 1912, 
contained the remains of a great number of Tufted Puffins and young Glaucous- 
winged Gulls (Willett, 1912, p. 421). 
Falco pereg'rinus anatum. Duck Hawk. Fairly well distributed among the 
islands but nowhere plentiful. Although the duck hawk of this region has been 
generally referred to F. p. pealei, specimens taken prove to be referable to anatum, 
as did specimens taken by the 1907 Alexander Expedition near Killisnoo, Ad- 
miralty Island (Grinnell, 1909, p. 215). On October i, 1913, I saw one of these 
hawks swoop down and carry off a Eorked-tailed Petrel from a small flock near the 
Sitka dock. 
Falco columbarius suckleyi. Black Pigeon Hawk. In the last A. O. U. 
Check-List (1910, p. 165) Sitka is given as a record station for this species. I 
am informed by Professor W. W. Cooke that this record is based on the range as 
given by Baird, Brewer and Ridgway (1874, p. 143) in the key to the species of 
the genus Falco. Here the habitat of F. c. suckleyi is given as “northwest coast 
region from Oregon to Sitka.” On page 147 the habitat is given as “coast dis- 
trict of northern California, Oregon and Washington (probably northward to 
Alaska).” The basis upon which Sitka is included in the range of the form as 
given on page 143 is not stated. Grinnell (1898, p. 123) mentions seeing pigeon 
hawks, presumably F. c. su-cklcyi, in the vicinity of Sitka during the summer of 
1896. On August 10, 1913, while at an altitude of about 2500 feet in the moun- 
tains near Sitka, I shot a very dark colored pigeon hawk. Unfortunately it fell 
into an icy lake where it was impossible to secure it. This was the only time I 
noted the "pigeon hawk in the region, and it must be regarded as far from com- 
mon. As four specimens secured by the 1909 Alexander Expedition at Thomas 
Bay, Port Snettisham and Taku River, on the mainland, proved to be referable
