THE AUDUBON BULLETIN 



The Marsh Hawk probably breeds on Rock River bottom; it is occa- 

 sionally seen here, flying low over the fields, hunting for its prey. They 

 are sometimes seen during the winter, as are also some of the other hawks. 

 The Red-headed- Woodpecker stayed here during the winter of 1915-1916; 

 there are many of them here at the present time, and will probably stay all 

 winter. The Prairie Horned Lark stayed here last winter, and are also 

 here at the present time. In 1916, the Goldfinch remained until Dec. 10; 

 they yet can also be seen and heard nearly every day. a
