TEANSAOTIONS OF THE 
7. Suteo Swainsoni Bon., and var. insignatus. (18.) Brown Hawk. 
Obtained a skin of tlie variety at Koyukuk, May 26th, 1867, from an 
Indian. This hawk, preferring the thickets and woody places, is not 
so often seen as some of the other species. It generally builds a very 
large nest of sticks, and begins to lay about the last of April. The 
young are hatched by open water, i. e., 25th to 30th of May, It is a 
summer visitor, and I found not only the bones of rabbits, squirrels and 
mice about its nest, but also those of ducks, and in one instance, part 
of a white-fish. D. 
8. Archihuteo lagopus Gray. (30.) Rough-legged Hawk. Obtained 
at Sitka and Kadiak by BischofF, and by myself, with the eggs, at Fort 
Yukon ; a rather rare bird in the vicinity of the Yukon. D. 
9. Circus hudsoniusY'\e\\\. (38.) Marsh Hawk. Very rare on the 
Yukon. Occasional at St. Michael's, where a male was killed in Novem- 
ber. A summer visitor. D. 
10. Aqiiila canadensis Cassin. (39.) Golden Eagle. A skin, from 
which the leg and wing bones and skull had not been removed or 
cleaned, was offered to me for sale, at St. Michael's, in June, 1868. It is 
the only specimen of this species I saw in the country, and was said 
to have come from the Shaktolik Hills, where it had a nest and two 
young. D. 
11. HalaeUis leticocephalus Sav. (43.) Bald Eagle. Nov. 16th, 
1867, saw at Iktigalik in the Ulukuk Valley, a skin of a young male 
of this species. It was in course of preparation for use in some of 
their Indian dances. The Indians state that it lives in the mountains, 
where it breeds, building on inaccessible clilFs. This (or A. canadensis) 
often carries off the young reindeer in the spring, and has been known 
to carry oif a child left exposed in the camp. Feeds principally on 
rabbits, grouse and young deer, but occasionally on fish in the fishing 
season. Very common at Sitka, where Bischoff obtained eleven 
specimens. D. 
12. Pandion carolinensis Bon. (44.) Fish Hawk. This species 
has been obtained from Sitka, with the eggs, by Bischoff. I obtained 
several specimens near Nulato, in May, 1867 and 1868. They appear 
to be not uncommon, but frequent the small rivers rather than the 
Yukon. They are summer visitors and build an unusually large nest, 
which they return to every season. D. 
13. Bubo virglnianus Bon. (48.) Great Horned Owl. Iris light 
yellow. Caught alive, June 18th, 1867, several young males, not fully 
fledged, except on the body, five days below Fort Yukon, on the Yukon 
River. Got a skin April 16tli, 1868, of an adult male, killed near Nulato. 
It is not common here, but is found more plentifully further up the river. 
Also at Sitka (Bischoft"). D.
