74 NORTH AMEKICAN FAUNA, [no. 19. 



The vving.s had Ixmui removed iit the cai'pal joint, ))ut the unruffled 

 plumage — the down yet persisting on the ends of the secondaries — 

 removes all probability that it had been a caged bird. This is the first 

 record of the occurrence of this species in western North America, 

 although it is common in Japan and occurs in Kamchatka and occa- 

 sionally on the Commander Islands. 



80. Haliaeetus leucocephalus alascanus. Northern Bald Eagle. 



We found this l)ird common along the Inside Passage, especially 

 near Wrangell Narrows, and from the steamer I noticed three occupied 

 nests. We visited one which was high in a gigantic dead cedar on a 

 small island near Bocadequadra. Broken shells at the foot of the tree 

 made it probal)le that the nest contained young. The female parent 

 was secured by Maddren. On the flats of Chilkat Inlet June 1 I saw 

 28 eagles feeding. Here I found another occupied nest at least 100 

 feet up in a living spruce (it was so high that heav}^ charges of No. 4 

 shot did the bird no harm). A man passing l)v shot the male with a 

 rifle. The next day I saw the female again on the nest. In the interior 

 this bird is much rarer, though I saw one at Log Cabin June 20, and 

 another at Bennett June 19. We saw the birds occasionally about the 

 lakes (I found a deserted nest on Lake Marsh), and once or twice 

 along the river, the last being observed near the White River July 31. 



81. Falco rusticolus. Gray Gyrfalcon. 



A female was caught in a steel trap set on a post at St. Michael 

 September 21. Its stomach contained feathers. The irides were 

 Vandyke brown; tip of bill and nails, black; tarsi, toes, cere, gape, 

 and rest of bill, pearl gray, the ))il] changing to pearl blue on maxilla 

 near commissure. 



82. Falco peregrinus anatum. Duck Hawk. 



At Fort Selkirk the character of the Yukon Valley changes, and 

 the high, sandy bluff's which have been constantly visible on one bank 

 or the other are frequently replaced by rocky cliffs of varying height. 

 Flying about one of these cliffs near Stewart River July 31 was the 

 first duck hawk we noted. From that point to the Yukon Flats, a 

 few miles above Circle, a day seldom passed without our seeing or 

 hearing them, and from Camp Davidson to Circle I think there was 

 at least one breeding pair every 10 miles. We saw a number of their 

 nests on shelves on the cliff's, but at this time, the first half of August, 

 the young had flown. 



Osgood secured a young female August .5 on the cliff known as 

 ' Old Woman,' and an adult female August 7 near the Tahkandik River, 

 and shot several others which he failed to bag. I took a young male 

 from a family on ' Castle Rock' August 5. We found that those taken
