Bird Life of North Dakota 73 



A few on their way south were seen at Devils Lake on August 17 and 

 21, 1920. Some were also noted there after May 23, 192 1. Mr. Williams' 

 Collection contains a mounted bird taken at Grafton, May 24, 192 1. 



270. Dendroica tigrina (Gmelin). Cape May Warbler. 



JuDD, 1917, p. 26; rare migrant, taken as early as May 13. Freeman, 1919, p. 15; 

 transient visitant, sometimes seen May 19. 



I did not see this species in life, but there is a mourKted specimen in the 

 Williams Collection taken at Grafton, June 5, 1920, by Henry Williams, 



271. Dendroica aestiva aestiva (Gmelin). Yellow Warbler. 



Allen, 1875, p. 52; abundant along the Missouri and Heart rivers, 1873. CouES, 

 1878, p. 565 ; this abundant species was observed at various points along the whole 

 line and in the Missouri region. Specimens were taken at Pembina, June 2 to 6, and 

 at Mouse River. August 23. 1S73. Judd, 1917, p. 26; common summer resident, nest- 

 ing in the prairie region and the Turtle Mountains. 



This species was common at Devils Lake after May 16, 1921. I found 

 it at all the localities worked, and believe it is a summer resident in suitable 

 habitats throughout the whole state. 



2y2. Dendroica cccrulesccns cccmlescens (Gmelin). Black-throated Blue 

 Warbler. 

 This species is not given in any of the published lists nor did I see it in 

 life, but I found a mounted specimen in the museum of the Agricultural 

 College at Fargo with no data. 



273. Dendroica coronata (Linnseus). Myrtle Warbler. 



CouES, 1878, p. 565; not seen until the middle of September, when it made its 

 appearance in abundance along the Mouse River, where specimens were taken Sep- 

 tember 16-18, 1873. Judd, 1917, p. 26; the most abundant warbler during migration, 

 seen last week inl April. Freeman, 1919, p. 15; very common, April 8. Bailey, 1920, 

 p. 105 ; yellow-rumped warblers were seen at Sweetwater Lake about the middle of 

 September, 1917. 



I found this species May 3, 192 1, on my arrival at Devils Lake, and 

 until May 19. It occurs as a migrant only, in North Dakota.

The species was) seen but twice, at Devils Lake on May 20 and 24, 1921. 

 Mr. Reid writes that he has only one record, Bismarck, ALiy 12, 1920. There 

 is a mounted specimen in the Williams Collection taken at Grafton, May 

 25, 1921.

prairies, nests in Turtle Mountains. FrEEMAN', 1919, p. 15; probably summer resi-
