a high degree of personal cooperation has been continually mani- 
fested in the Cooperative Dove Investigation. Biologists working 
throughout the eastern part of the Mourning Dove range have exchanged 
progress data freely and allowed its use in the "Mourning Dove News- 
letter" series in order that all workers might be kept informed promptly. 
This report again is a cooperative endeavor since it represents research 
financed by the Fish and Wildlife Service, Branches of Wildlife Research 
and Federal Aid; the Georgia Game and Fish Commission; the Tennessee 
Division of Game and Fish; the Wisconsin Conservation Department; the 
University of Georgia; the University of Tennessee; the University of 
Wisconsin; and the Wildlife Management Institute. Each of the papers 
in this report is intended as a separate contribution and there have 
been no editorial changes made in the original treatment of subject 
matter. Full credit should go to the individual authors. Many in- 
dividuals, State and Federal employees, and students have contributed 
abnormal working hours to record the data herein summarized. Without 
the friendly cooperation of all concerned, these parallel investigations 
could not have been made.
