Mr. Julius Hurter (Bull. Xutt. Orn. Club. 1881, p. 124) records 

 an immature specimen taken in Marion Co., 111., near St. Louis, in 

 February, 1880, which was identified by Prof. Ridgway as this species, 

 but later Mr. Ridgway (Ornithology of 111., 1895, p. 112) suggests 

 the possibility of its being an immature specimen of guarauna on 

 account of the coloring of the legs and bare skin in front of the eye 

 in life, as described to him in a letter from Mr. Hurter. Nelson 

 writes: " A very rare visitant. I know of but two or three instances 

 of its occurrence." In Wisconsin, according to Kumlien and Hol- 

 lister, seven specimens have been observed and one shot on Lake 

 Koshkonong in 1872, and another was killed on Horicon Marsh, in 

 1879. It has also been recorded from Michigan (Cook), and Iowa 

 (Anderson).
