THE NATURAL HISTORY SURVEY. 159 



W. Nelson recorded it as a common migrant.* I have the fol- 

 lowing recent records of the taking of this species : On May 29, 

 1885, I obtained a specimen in Hyde Park, Chicago; September 

 10, 1888, and August 28, 1895, Mr. B. T. Gault obtained speci- 

 mens in Chicago; May I, 1896, and ori October i, 1896, Mr. 

 Gault also obtained specimens in Du Page County, Illinois ; on 

 April 29, 1893, Mr. F. S. Dayton obtained a specimen at Bow- 

 manville, Illinois. In his Birds of Indiana,f Mr. Amos W. But- 

 ler has published the following records for our area: "In 1871, 

 Mr. C. E. Aiken informs me, it was not rare in Lake County, 

 Indiana. In that county, also, Mr. H. K. Coale obtained a speci- 

 men, May 1 6, 1877, and two days later one in Cook County, Illi- 

 nois, not far away. The next record I have from Cook County 

 is of a specimen taken by Mr. C. A. Tallman, May 15, 1897." 



The range of this species extends through eastern North 

 America from Mexico northward. It breeds as far north as the 

 Yukon and Mackenzie River districts and southward through 

 the Rocky Mountains. It is rare north of Virginia and east of 

 the Alleghany Mountains. It migrates southward, in winter, 

 chiefly through the Mississippi Valley and westward to the Great 

 Basin, and winters in the southern states and Mexico.

The Tennessee Warbler is a common migrant, the majority 

 arriving within our limits in the month of May, and returning in 

 the fall from the middle of August to the middle of October. 



The range of this Warbler extends through the United 

 States, east of the Rocky Mountains and it breeds from the north- 

 ern border of the United States northward to the Arctic regions. 

 It winters southward through eastern Mexico to the northern 

 part of South America.
