Summa ry 
Thie season marked the first attempt to appraise waterfowl production in 
Indiara, and much of the work was investigative. Eiver floats, car traneects, 
foot coverage of study areas, and numerous scouting trips: were ron in order 
to locate nesting populations. Field work was conducted from May 1 to July Zl. 
Three major sofl regions were investigated during the process of carrying 
out the shove censusing. [It is thought that theeae three reZzione comprise the 
principal breeding range of waterfowl in Indiana, except for the wood duck which 
is known to breed throughout the State. 
Until the survey la placed on a asils basis, thie season's results should 
not be given too much significance. It 1i# hoped that a more complete and 
ayatematic survey can be instituted mext senecn.
