There is only one valid record known to me of the occurrence of 

 this northern species in Illinois, viz., that by Mr. Nelson in his 

 list of the birds of the northeastern portion of the State {Bull. 

 Essex Inst. Vol. VIII., 1876, p. 117), where its capture in Kane 

 county, by Dr. J. W. Vehe, the first of September, 18G9, is noted.
