Air. W. W. Cooke records specimens taken at Chicago, March 28, 

 1884, and May 3, 1895. 



Another record for the vicinity of Chicago is that of an adult male 

 taken by Mr. H. K. Coale, Chicago, 111., May 5th (Sharpe, Cat. Birds 

 Brit. Mtis., Vol. X, 1885, p. 439). 



Messrs. Kumlien and Hollister say: "Not an uncommon migrant 

 along Lake Michigan in southern Wisconsin and it undoubtedly 

 breeds to the northward of Milwaukee. Much less common in the 

 interior than along the lake shore. We have seen this species re- 

 peatedly at Two Rivers in July, but in Jefferson, Dane, and Rock 

 counties only in the spring migration in May. We have also taken 

 specimens at Milwaukee in the latter part of May." (Birds of Wis- 

 consin, 1903. p. 119.) 



The nest is in low bushes in swampy woods. The eggs are 3 or 4, 

 usually 4, white or bufify white, speckled and marked chiefly at the 

 larger end with dark brown and brownish gray and occasionally a 

 few specks of black. Size, about .70 x .54 inches.
