All that can at present be said of Barrow's Golden-eye as a 

 bird of Illinois is that it is a rare winter visitant, reaching- here 

 about the southern limit of its distribution. Comparatively 

 little is known as to its habits, which, doubtless, in the main, 

 closely resemble those of the common species.
