Types of duck hunting in Wisconsin include decoy shooting, 
jump shooting and pass shooting. Although some counties have all 
three types of shooting, many have but two, and some have only one. 
Decoy shooting is the most prevalent, with forty-two counties listing 
this as an important type of duck hunting; twenty-one list jump 
shooting and seventeen have pass shooting. 
A questionnaire, by counties, with reference to the effect, if 
any, of mudhens, muskrats and carp on duck foods was answered as 
follows: Observers in forty-eight counties estimate that mudhens are 
not abundant enough to have an effect on duck foods. Observers in 
ten counties believe that mudhens are of such abundance as to serious- 
ly affect the waterfowl food supply. Forty-nine counties estimate 
that muskrats are not of sufficient abundance to affect waterfowl 
foods, while observers in seven counties believe that muskrats are 
plentiful enough to have an effect on duck foods. Observers in twenty 
five counties believe that carp have a serious effect on the majority 
of waterfowl plants; observers in twenty-nine counties (the majority 
of these are in the northern part of the state where there are no 
carp) have noticed no ill effects on these foods from carp. Many 
observers believe that great swarms of black-birds have a serious 
effect on wild rice beds. 
Comments on the waterfowl situation in Wisconsin during a recent 
survey include many notations on the great increase of wood ducks in 
many waters of the state. There are, in nddition, many requests for 
legislation closing shooting hours in the afternoons and requests for
