The Raven is a vei-y local and nowhere abundant bird in Illinois, 

 The writer has seen it only in the bottoms of Big Creek and about 

 the borders of Fox Prairie, in Eichland County, where, up to 1871 at 

 least, one or two pairs might be seen at almost any time, usually soar- 

 ing in circles over the timber. It was never observed in the vicinity 

 of Mount Carmel, nor have I ever been able to hear of its oc- 

 currence anywhere in that portion of the State except in the locali- 

 ties mentioned. According to Mr. Nelson it was "formerly a not 

 uncommon resident" in the northeastern portion of the State, but 

 "now [1876] occurs only in winter and is rare." Mr. Nelson further 

 remarks : "Frequents the sand hills along the lake shore from the 

 last of October until spring. The fu'st of November, 1875, I saw 

 several specimens near Waukegan, where they were repeatedly seen 

 flying along the lake shore, and in winter they unite in small flocks 

 and move from place to place."
