72 Seton, Bird Records from Great Slave Lake. {,'jdu 



Redwing. Agelaius phneniceus arctolegus. Slave River Delta, July 16. 



Rusty Blackbird. Euphagus carolinus. Noted at several points 

 along Great Slave Lake. At Kipling Lake, on Pike's Portage, 10 miles 

 east of Fort Reliance, saw young of the year, now fully fledged, July 29. 



Pine Grosbeak. Pinicola enucleator. First seen on Et-then Island, 

 Great Slave Lake, Sept. 21. Afterwards seen daily as we journeyed south- 

 ward. 



Red Crossbill. Loxia curvirostra minor. Saw one on Great Slave 

 River Delta, Sept. 28. 



Lesser Redpoll. Acanthis linaria. Common on Pike's Portage, 10 

 miles east of Fort Reliance July 30, and thence northward to the edge 

 of the woods. Evidently on its breeding ground. 



Snowbird. Passerina nivalis. First seen on the large central island 

 of Clinton-Colden Lake, Aug. 11. Old ones with young of the year. After 

 that, while we were going northward, others were seen, evidently on their 

 breeding grounds, but it was not a common species. 



Lapland Longspur. Calcarius lapponicus. Beginning exactly at the 

 edge of the woods and continuing as far as we went in the Barrens, were 

 countless Lapland Longspurs. I think I did not see a dry ten-acres in the 

 treeless region that was without at least two pairs of Longspurs. During 

 the time we were there, Aug. 1 to Sept. 8, they were in flocks, at first of half- 

 a-dozen, but finally of hundreds; in migration at Fort Reliance Sept. 14. 



Painted Longspur. Calcarius ornatus. One seen on the north shore 

 of Ay liner Lake Aug. 13. 



Western Savanna Sparrow. Passerculus sandwichensis alaudinus. 

 Observed along the whole route in the Barrens, but nowhere plentiful and 

 not seen in flocks. Several appeared about Fort Reliance in mid-Septem- 

 ber. 



Hooded Sparrow. Zonotrichia querula. First seen on Kahinouay 

 Island, Great Slave Lake, as we went North, July 20; it was there nesting. 

 After that they were abundant, nesting in every large thicket right to 

 the edge of the Barrens. In the Last Woods Aug. 5, I found the nest, the 

 first I believe known to science. It was on the ground under a dwarf 

 birch, was made of grass and resembled the nest of the White-throated 

 Sparrow. It contained three young nearly ready to fly. I found this 

 species in full song Sept 3. 



Gambel Sparrow. Zonotrichia gambeli. Abundant on islands in 

 Great Slave Lake in late July. 



White-throated Sparrow. Zonotrichia albicollis. Abundant at the 

 mouth of the Great Slave River, but not seen farther northeasterly. 



Tree Sparrow. Spizella monticola. First noted near the east end of 

 Great Slave Lake; afterward abundant and nesting to the Barrens where 

 there were small thickets. About the 1st of September the Tree Sparrows 

 were gathered in small flocks to migrate and now were seen out on the Bar- 

 rens many miles north of the summer range. 



JuNco. J unco hyemalis. Generally diffused, at least as far as the east 

 end of Great Slave Lake.
