Summary 
In southern Ontario, an extensive survey of breeding waterfowl conditions 
was carried out by the author. More restricted and local surveys were carried 
out by Messrs. H. G. Lumsden and N. D. Patrick of the Fish and Wildlife Division, 
Ontario Department of Lands and Forests in the Quinte and Rideau districts of 
southern Ontario. The results of all three surveys are summarized in this report. 
Weather and water conditions throughout the area were ideal for waterfowl 
nesting and brood rearing. 
In all, 58 habitats were examined by the 3 observers. Nineteen species of 
waterfowl were found in the area, but only 16 of these are classed as breeders. 
There was little change in the relative populations of the various breeding species. 
Black duck, blue-winged teal, ring-necked duck, common goldeneye, mallard and 
wood duck are the important breeders. 
Brood production was about normal but there was some indication that 
black duck, hooded merganser and common merganser produced larger broods 
than in 1951. Wood duck and common goldeneye broods were smaller than in 1951.
