470 NORTH AMERICAN FAUNA. [no. 27. 



Fort Good Hope, and Fort Andersons In addition both skins and 

 eggs were received by the Smithsonian Institution from Lesser Slave 

 Lake; and eggs from the Hudson's Bay Company post on Pelican 

 Lake, eastern Saskatchewan, taken in June, 1891, were received 

 through MacFarlane. Several individuals from the upper Macken- 

 zie Valley, and 2 taken near the mouth of the Athabaska, June 20, 

 1892, by Miss Elizabeth Taylor, are in the National collection. Rus- 

 sell took several specimens May 24 to June S, 1893, at Fort Chipe- 

 wyan, and states that the species arrived on the former date. 6 

 Macoun states that Spreadborough first noted this bird on May 12, 

 1897, at Edmonton ; found it abundant between that place and Atha- 

 baska Pass in June, 1898 ; and observed it from the mouth of Lesser 

 Slave River to Peace River Landing in June, 1903. c 



The earliest dates recorded in the catalogue of the birds in the 

 National Museum are as follows: Fort Resolution, May 2G, 1860; 

 Fort Simpson, May 29, 1860 ; May 26, 1861. They probably repre- 

 sent approximately the dates of arrival. 



Dendroica coronata (Linn.). Myrtle Warbler. 



This hardy warbler is a fairly common summer resident north to 

 the tree limit and is the earliest warbler to arrive in spring. 



In 1901 we saw one in a thicket about 40 miles south of Athabaska 

 Landing, May 4. We next noted the species at Fort Chipewyan, 

 May 21, when specimens of both sexes were taken, and again on 

 May 24. I took a male at Fort Resolution, July 6, and saw several 

 at Fort Rae, July 27, collecting two birds of the year. 



In the spring of 1903 we first observed the myrtle warbler at 

 Edmonton, May 8, noting a single male. We saw 2 individuals near 

 Sturgeon River, May 12, and found the species common between 

 there and Athabaska Landing, May 13 to 15. While descending the 

 Athabaska we noted it near Swift Current, May 17; between there 

 and Grand Rapid, May 18 and 19; below Little Buffalo River, May 

 26; and on the lower part of the river, where it was rather common, 

 May 31. It was noted near the outlet of Athabaska Lake, June 5, 

 and was next observed on Slave River below Fort Smith, where it 

 was rather common, June 16 to 19. While ascending the Athabaska 

 on their return trip Alfred E. Preble and Merritt Cary saw 4 indi- 

 viduals, collecting 2, 50 miles above Pelican Rapid, August 27, and 

 found it rather common near Athabaska Landing, September 4 to 15. 

 During my trip northward from Fort Rae, I noted a flock of 

 migrants near Lake St. Croix, August 14, taking a specimen, and 

 also observed the species on Lake Hardisty, August 18, and a few
