The Black Vulture is not uncommon in southern Illinois, and ac- 

 cording to Prof. Ridgway (Orn. of Illinois, Vol. I, 1889, p. 492) occurs 

 at least as far north as Mt. Carmel. It has apparently not been taken 

 in Wisconsin. 



Kumlien and Hollister (Birds of Wisconsin, 1903, p. 131.) write: 

 " We do not consider the records of this species for Wisconsin 

 sufficiently authentic to warrant us in giving it a place at the present 

 time."
