THE NATURAL HISTORY SURVEY. I93 



The Willow Thrush is a not uncommon migrant in suitable 

 localities of our area. In the spring, it arrives from the last 

 of April to the last of May, and returns, in the fall, from the last 

 of August to the middle of September. The following are the 

 records of the taking of this species within our limits, which are 

 known to me, and they also indicate the localities where these 

 birds may be found more frequently at the proper seasons : 



On September i6, 1877, Mr. Henry K. Coale captured a 

 specimen near Chicago. This is the first record of its occurrence 

 in Illinois. 



Mr. J. Grafton Parker, Jr., took a specimen at Grand Cross- 

 ing, Illinois, on April 29, 1886. This was a male bird. He also 

 captured two birds at Liverpool, Indiana, on May 5, 1894. 



Mr. B. T. Gault captured a male of this species on the sixth 

 and a female on the twenty-first of May, 1894, at Glen EUyn, 

 Illinois. 



Mr. Frank M. Woodruff took this species at Evanston, Illi- 

 nois, on April 27, 1896. 



Mr. B. T. Gault also obtained a specimen in DuPage County, 

 Illinois, on September 17, 1896. 



Mr. Henry K. Coale obtained a specimen at Ravinia, Illinois, 

 on May 17, 1890. 



While the records mentioned show the actual taking of speci- 

 mens, others have been seen in the same localities. It is well 

 to bear in mind that this variety closely resembles pale specimens 

 of Hylocichla fuscescens. 



The range of the Willow Thrush as given in the A. C. U. 

 Check-list of North American Birds (1895) is as follows: 

 "Rocky Mountain region, north to British Columbia, east to 

 Dakota, occasionally to Illinois, casually to South Carolina; in 

 winter south- to southern Brazil." 



Hylocichla aliciae (Baird). Gray-cheeked Thrush. 



Turdus alieim Baird, B. N. Amer., 1858, 217. 



Turdus swainsoni var. aliciw Cotjes, Key, 1872, 73. 



Hylocichla aliciw RiDGWAT, Proc. TJ. S. Nat. Mus., Ill, August 27, 



1880, 166.

The Gray-cheeked Thrush is an abundant migrant, arriving, 

 in the spring, from the first to the last of May, and returning, in 

 the fall, from the last of August to about the second week in 

 October.
