DEDICATION 



Wildlife disease research in what is now the U.S. 

 Fish and Wildlife Service originated in the early 

 1900's with investigations within what was then the 

 Bureau of Biological Survey. Losses of millions of 

 birds to an unknown malady, later determined to be 

 avian botulism, stimulated the beginning of concen- 

 trated scientific research involving disease problems 

 in migratory birds. 



Much of what is currently known about this disease 

 in migratory birds resulted from research conducted 

 at the Fish and Wildlife Service's Bear River 

 Research Station in Brigham City, Utah. These 

 research efforts span 30 years of time, from the early 

 1940's to the mid-1970's. For approximately 25 years 

 of that time, Dr. Wayne I. Jensen, Microbiologist-in- 

 Charge of that station, dedicated his efforts toward 

 developing an understanding of avian botulism that 

 could eventually lead to prevention and control of this 

 disease. 



We dedicate this publication to Dr. Jensen in recognition of his personal dedication, pro- 

 fessionalism, high scientific standards, and personal sacrifices in carrying out his research 

 efforts. He has inspired our own scientific development and investigative efforts and is 

 truly an outstanding individual.
