 Smith Portage June 18 : several were seen and one was taken at Fort

In 1903 we noted it on the lower Athabaska May 31 and June 1. 

 ]My brother and Gary saw it at Fort Providence July 7. and at Fort 

 McMurray August 11. AYliile ascending the Mackenzie I saw one 

 a short distance below Xahanni Eiver October 13. At Fort Simp- 

 son I took single birds Xovember 21 and December 3. 



In the spring of 1901 I did not detect this bird, but H. AY. Jones 

 took one at "Willow River, near Fort Providence. May 7. 



Under the name Picus iml^escens. Ross recorded it as being not 

 rare in the Mackenzie River region north to Fort Liard. and as win- 

 tering.'^ A specimen in the Xational Museum, taken at Fort Resolu- 

 tion October 1, 18r52. by J. Lockhart. has been referred by Oberholser 

 to this form.^ and the catalogue of the birds in that collection records 

 another specimen from Fort Liard. Macoun states that J. M. Macoun 

 noted a few along the Athabaska, and reported it rare between Methye 

 Lake and Isle a la Crosse, in the summer of 1888.^ 



In the summer of 1890. while on his way to Jasper House. J. Alden 

 Loring reported seeing several in the valleys of the foothills about 

 SO miles east of the Rocky Mountains. 



Picoides arcticus (Swains.). Arctic Three-toed AVoodpecker. 



The black-backed three-toed woodpecker is of regular occurrence 

 in the region north at least to about latitude 63° on the Mackenzie, 

 but is the less common of the two species of Picoides. 



Durino^ the season of 1901 it was noted but once — a male beino- taken 

 on the Athabaska about 25 miles below Athabaska Landing, Au- 

 gust 28. 



In 1903 Alfred E. Preble and Merritt Gary saw one about 20 miles 

 above Fort Wrigley July 19. On their outward trip they observed 

 one at House River August 22, and collected a pair on an island 

 above Athabaska Landing SejDtember 11. During the same season I 

 saw the species but once, taking a male at Fort Simpson October 21. 



In 1901 I observed single birds at Fort Simpson on March 8. 22, 

 and 28, taking specimens on the last two dates. AVhile descending 

 the Mackenzie I saw one near Fort Wrigley June 7, and on my return 

 trip observed one in a pine forest near Lily Lake, Alberta, Sep-
