Aegialitis semipalmata (Bonaparte). Semipalmated Plover. 



This plover was first seen in its breeding grounds on Artillery 

 Lake, near the tree limit, on August 2, and others were observed 

 at the same place on August 4. We observed it also near the 

 eastern end of Aylmer Lake on August 13, and at its western ex- 

 tremity on August 15. 



Canachites canadensis canadensis (Linn.). Hudsonian Spruce 



Partridge. 



Although the spruce grouse occurs over the entire wooded 

 region north of Edmonton, we failed to observe it during our 

 passage down the rivers, and saw but few during the entire sea- 

 son. We noted two on the lower Nyarling on July 8. The 

 species was next seen on lower Slave River on September 29. 

 We noted a few near Grand Devour on October 2 and 3 while 

 tracking along the eastern bank of the Slave between Salt River 

 and Fort Smith, we noted eight individuals in twos or threes. 

 Several were seen while we were driving across the portage be-

 species was last seen on the Athabaska, below Calling River, on 

 the morning of October 1, when a single bird flew into our camp 

 just as we were leaving it. 



Bonasa umbellus umbelloides (Douglas). Gray Ruffed Grouse. 

 The presence of ruffed grouse, usually evidenced by the drum-

 May 18; near Brule" Rapid, May 26; near Fort McKay, May 

 31 and June 1, and near Poplar Point on June 2 and 3. We 

 also heard the species drumming near Smith Landing on June 

 9, and noted it on Little Buffalo River on June 26. It was last 

 noted on our northward trip in the Slave delta, near Fort Reso- 

 lution, on July 16. During our return trip we saw a few while 

 making the portage across the Grand Detour on October 2, and 

 we saw one near Fort Smith on October 5. While ascending 

 the Athabaska the species was noted above Poplar Point, Octo- 

 ber 13, and we heard two drumming at intervals during most of
