1908.] BIRDS. 877 



on two occasions, taking' a bird of the year near Sarahk Lake August 

 6, and noting one on Lake Hardisty August 19. While ascending 

 the Mackenzie I saw one at Roche Trempe-l'eau October 0. It had 

 in its talons the remains of a rutted grouse 1 , freshly killed and partly 

 eaten, which it seemed to carry without difficulty. At Fort Simpson 

 on October :21 I took a female bird, the last one observed that season. 



During the coldest months of the winter this bird was not observed. 

 and it was next seen at Fort Simpson on March 28, L904, when I col- 

 lected a female. This bird swooped upon a Hock of redpolls, but 

 failed to secure one, and alighted for an instant on the summit of a 

 small dead tree. I observed single birds on April 5, 1-1, and 21, 

 securing the last-mentioned individual. A bird seen May 1!> dropped 

 a freshly killed meadow mouse {Microtus drummondi) when started 

 from its perch. While descending the Mackenzie I saw two a short 

 distance below Fort Norman June 1G. and on my return trip observed 

 one at Wrigley Harbor, Desmarais Islands, July 30. 



Two specimens, both females, taken by J. W. Mills at Fort Simp- 

 son October 9. 1901, and February 13, 1905. respectively, have been 

 recently received. 



Richardson first recorded this species from the region, mentioning 

 several killed at Great Bear and Great Slave lakes;" King noted it 

 on. Back River, at the cascades above the mouth of Baillie River. 

 September 11, 1834 ; 6 Thomas Simpson states that it was taken at 

 Fort Confidence during the winter of 1837-38. c In 1S62 Ross re- 

 corded it as common in the Mackenzie River region north to the 

 Arctic coast, as wintering in the region, and as having been taken at 

 Fort Simpson.'' MacFarlanf speaks of it as not uncommon in the 

 Anderson River region, where a number of nests were discovered. - 

 Baird, Brewer, and Ridgway state that Ross had received eggs of this 

 species from La Pierre House and Salt River, and also describe an 

 egg from Fort Simpson/ Bendire records nests containing eggs on 

 April 28 and May % 2. and one containing young on dune •_'(), L863, all 

 discovered by MacFarlane in the Anderson River region, also an egg- 

 taken by the same collector at Fort Providence April 11, L885, show- 

 ing that the bird breeds rather early." MacFarlane's manuscript cata- 

 logue records also a female taken with six eggs at Fori Anderson on 

 May 21, 1863. The bird catalogue of the National Museum records 

 skins received from Fort Resolution. Fort Rae, Big Island. Fort
