Summary 
Waterfowl breeding ground surveys were initiated in Connecticut in 1946, 
Two types of surveys have been used; ground coverage of selected areas 
and aerial coverage using transects which cover the State. 
Aerial surveys started in 1951 have presented difficulties which influence 
the validity of data collected and which as yet have not been ironed out. 
Ground surveys which have been conducted for five years indicate: 
1. The chief species of duck breeding in Connecticut to be 
Wood duck, Black duck and Mallard. 
2. The importance of the Wood duck as a breeding duck in 
Connecticut, ranking first in numbers on the 
survey until 1952, 
3. A recent increase in the number of Mallards breeding 
in Connecticut. 
4. Avrather spectacular increase in the Black duck population 
during the summer of 1952, 
5. A low in summer waterfowl populations during 1950. 
6. Ahigh in summer waterfowl populations in 1952.
