next seen on the Barren Grounds, near Muskox Lake, on August 

 21 ; others were seen near the outlet of CHnton-Colden Lake on 

 August 30, and near the eastern extremity of Great Slave Lake 

 on September 10. 



Haliaetus leucoceplmlus aldscanw Townsend. Northern Bald 

 Eagle. 

 The first bald eagle was seen while we were paddling westward 

 along the northern shore of Kah-d'nouay Island on September 

 23 during our return trip. Here we saw a bird in immature 

 plumage, probably a young one of the year, make three attempts 

 to capture a fish without success. We observed the species also 

 on the Athabaska, near the site of the old post, Pierre au Calumet. 

 Another was seen a few miles north of Edmonton on Novem-

Falco peregrimis anatum Bonaparte. Duck Hawk. 



The duck hawk was observed in the delta of the Athabaska 

 on June 4. We next noted the species near the western end of 

 Clinton-Colden Lake on August 12, noting two; and we saw one 

 near our camp on Sandhill Bay, Aylmer Lake, August 20. 

 During our southward voyage down Artillery Lake we saw three 

 about the rocky mound known as the Beaver Lodge. They 

 were very noisy and were swooping about high in the air playing 

 with each other. A nest on the face of the cliff overhanging the 

 water had probably been the home of these birds. One of them 

 was melanistic. 



Falco columbarius columharius Linn. Pigeon Hawk. 



Examples of this species were seen on the Athabaska, near 

 Fort McKay, on May 30, near Poplar Point on June 1, and on 

 Slave River, near Smith Landing, on June 7. The species was 

 next noted on Great Slave Lake, near The Narrows, July 22. 

 During our return trip we saw two at Fort Reliance on Septem- 

 ber 14, one of which was collected on September 21 while we were 

 encamped on Caribou Island, Great Slave Lake. We saw one
