I. INTRODUCTION. 
It is the purpose of this paper to describe the results of work 
which was begun with the idea of studying bird habits intensively. 
I learned through Mr. Henry L. Ward, curator of the Milwaukee 
Fia 1.—Map showing locations of gull colonies in region of Green Bay, Wisconsin. 
Public Museum, that colonies of herring gulls were to be found breed- 
ing on islands off both coasts of the peninsula which forms Door 
County, Wis., i. e., in Green Bay and in Lake Michigan.
