82 THE CONDOR VoL XVI 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.' 11uteo borealis alaseensis. Alaska Red-tail. Seen occasionally from the coast
up to 40oo 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, I9I 3, 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 (I882, p. I62) records a specimen taken near Sitka June 5, i88o. J. Dixon took a specimen at Port Frederick, Chichagof Island, July 28, I9O 7 (Grinnell, I9O9, p. 2?I). Archibuteo lagopus sancti-johannis. Rough-legged Hawk. Taken at Sitka by Bischoff (Dall and Bannister, I869, p. 272 ). Haliae?tus leueoeephalus alaseanus. Northern Bald Eagle. The most c0m- mon raptorial bird of the region, . occurring frmn 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 GulIs (Willett, I912, p. 42I). Faleo peregrinus ariaturn. 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 anatu_m, as did specimens taken by the I9O 7 Alexander Expedition 'near Killisnoo, _Ad- miralty Island (Grinnell, I9O9, p. 215). On October I, I9I 3, I saw one of these hawks swoop down and carry off a Forked-tailed Petrel from a small flock near the Sitka dock. Faleo eolumbarius suekleyi. Black Pigeon Hawk. In the last A. O. U. Check-List (I9Io, p. I65) 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 (I874, p. I43) in the key to the species of the genus Falco. Here the habitat of F. c. xuckleyi is given as "northwest coast region from Oregon to Sitka." On' page I47 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 ?43 is not stated. Grinnell (I898, p. I23) mentions seeing.pigeon hawks, presumably F. c. suckleyi, in the vicinity of Sitka during t.he summer of I896. 'On August .IO, I9I 3, 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 a? far from com- mon. As four specimens secured by the 19o 9 Alexander Expedition at Thomas Bay, Port Snettisham and Taku River, on the mainland, proved to be referable
