432 BIRDS OF ARCTIC AMERICA MACFARLANE. 



strongly resembled the Deigiiboriug vegetation. At the same time the 

 female sat so very closely that more than one was caught on the nest; 

 and I recollect an instance where the female bird, on the very near 

 ai)proach of our party, must have crouched as much as possible, in the 

 hope that she might not be noticed, which would have happened had 

 not one of the smartest of our Indian collectors caught a glance other 

 eye. Although lots of male ''Eockers" were observed on our summer 

 trips, feeding and otherwise disporting themselves in the " Barrens," 

 yet com{)aratively few nests were obtained, and exce[)t in 1802 not one 

 well identified example was discovered west of Hortou River, but dur- 

 ing winter scores of L. rupestris were met with in the forest country 

 east of Fort Anderson. 



308. Pediocaetes phasianellus (Liuu.)- Sbarp-taik-d Grouse. 



This grouse breeds in the i)ine forests on both sides of the Lockhart 

 and Upper Anderson Rivers, where one or two nests were met with, 

 but the eggs were afterwards lost. 



331. Circus hudsonius (Liuu.). Marsh Hawk. 



In June, 1805, an Esquimau snared a female bird on her nest on a 

 willow bush along the Lower Anderson Kiver. It contained five Qg.g!^. 

 In June, 1800, a nest composed of twigs and grasses, etc., was found in 

 a similar position ; there were six eggs, but they were unfortunately 

 among those lost that season. 



334. Accipiter atricapillus (Wilson). Aiuericau Oo.sliawk. 



This si)ecies is confidently believed to breed, in small numbers how- 

 ever, in the wooded country between Fort Good Hope and the Ander- 

 son. 



342. Buteo s'waiusoni Bouap. Swaiuson's Hawk. 



In July, 1801, we discovered a nest of this sjiecies which was built 

 on a spruce tree along Onion River, the ])rincipal tributary of the 

 Lockhart. It contained two well-grown birds. Both i)arents were 

 about and made a great ado in endeavoring to protect their offspring. 

 The male was shot. In June, 1865, another nest was found on the toi) 

 crotch of a tall pine in a ravine some 20 miles southeast of Fort Ander- 

 son. In composition it was similar to the nest of an Archibutco. The 

 female was shot as she got off her nest, which contained but one egg in 

 a well developed stage. The male was not seen. 



347a. Archibuteo lagopus sancti-johaniiis (Gmel.) American Koiigli lejjged 



Hawk. 



This form of A. htgopus is abundant in the Anderson district, as 

 specimens have been obtained from all parts of the surrounding forest 

 to the borders of the Barrens, as well as from the Arctic coast. I
