This is an eastern species which reaches in Indiana, almost the 

 western limit of its range. It has been noted by Mr. J. G. Parker, Jr., 

 at Kouts, Ind., December 10, 1896. Mr. Ruthven Deane reported 

 it from English Lake, February 14 and 15, 1891. The greatest num- 

 bers are reported in March, while migrating. It is rare in Franklin 

 County, and has been reported in the following counties: Carroll 

 (Prof. B. W. Evermann); Lake (Meyer, Parker, Aiken); Starke (Dury, 

 Deane); Laporte (J. W. Byrkit): Allen (C. A. Stockbridge); Dekalb 

 (Mrs. J. D. Hine); Putnam (J. F. Clearwaters); Decatur (Prof. W. P. 

 Shannon); Kouts (J. G. Parker, Jr.); Wabash (Ulrey and Wallace). 



Mr. Parker has found them at Kouts on the Kankakee River, appa- 

 rently paired, April 15, 1892, and Mr. Deane noted a pair in the 

 marsh at English Lake as late as May 10, 1891. They are usually 

 paired by the latter part of March. While I have no account of its 

 breeding in Indiana, I have no doubt it will be found to do so. Mr. 

 E. W. Nelson found one or two pairs nesting on the Calumet marshes 

 (Birds of Northeastern Illinois, p. 159). Mr. L. T. Meyer says it prob- 

 ably breeds in Lake County, and Mrs. Jane L. Hine reports it a sum- 

 mer resident in Dekalb County.
