Zonotrichia albkollis (Gmelin) . White-throated Sparrow. 



The white-throated sparrow is a common breeder throughout 

 the region covered on our trip north to Great Slave Lake. Some 

 localities with dates of observation follow: Grand Rapid, Atha- 

 baska River, May 24; Fort McMurray, May 28 and 29; Fort 

 Chipewyan, June 5; Smith Landing, June 11; Fort Smith, 

 June 24; Little Buffalo River, July 7, and Nyarling River, July 

 9 to 11. 



During our southward trip we observed the species on lower 

 Slave River on September 25 and 29. 



Spkella monikola monticola (Gmelin). Tree Sparrow. 



Migrating tree sparrows were seen during our northward trip, 

 near Edmonton, May 11; at Athabaska Landing, May 13 to 18, 

 and on the Athabaska River, near Pelican Portage, on May 19. 



The bird, now on its breeding grounds, was next observed on 

 Pike's Portage between Great Slave Lake and Artillery Lake on 

 July 28. From this point onward it was abundant and was ob- 

 served in numbers practically every day during August on our 

 trip through the great lakes between this point and the head of 

 Black River, and during our return trip through the same bodies 

 of water. It was common also, and was observed almost daily, 

 usually in numbers, during our voyage westward among the 

 wooded islands of Great Slave Lake during the latter part of 

 September. We noted it also on the lower Slave on October 1 ; 

 near Grand D6tour, October 3; near Fort Smith, October 4 and 

 5; above Smith Landing, October 7; near Fort Chipewyan, 

 October 8; near Fort McKay, October 15, and below Fort 

 McMurray, for the last time during the season, on October 16. 



Spizella passerina arizonm Coues. Western Chipping Sparrow. 

 The chipping sparrow was not seen during our descent of the 

 Athabaska, and was first observed near Fort Chipewyan on 

 June 5. Others were seen at Smith Landing on June 8 and 9, 

 and at Fort Smith daily, June 13 to 20. A nest was found near 

 the mouth of Salt River on June 27, and the species was obsen-ed
