"The Brown Pelican has a somewhat doubtful claim to be in- 

 cluded among the birds of Illinois. Apparently the only record is 

 that given by Mr. Chas. K. Worthen in a letter to Prof. Ridgway, 

 who writes: "Saw a specimen of this bird flying over Lima Lake, 

 a large, shallow body of water ten miles below here (Warsaw, Illinois), 

 in October, 1873. The bird was not over a hundred yards from myself 

 and two or three others and we watched it for several minutes. * * * 

 It had the color, bill, and size of that species." (Ridgway, Bull. 

 Nutt. Orn. Club, 1880, p. 31.)
