A report by A.. T. Cringan gives waterfowl breeding information obtained 
incidental to a muskrat survey in the Sioux Lookout District (Latitude 52° 50! 
Longitude 91° 55'). Five. Lakes, Petownikip, Sakwaso, Nikip, Magiss and Senia, were 
in the study area. Two environmental factors of special note were recorded: (1) the 
late break-up on June 2 (2-3 weeks behind schedule); (2) the persistence of high water 
throughout the summer. 
Mallards were the most common of the ducks seen. They were well 
distributed about the lakes and along the streams. Three nests were found and in late 
August a. brood was seen repeatedly with the young still unable to fly by September 1, 
Green-winged teal were generally distributed throughout the study area, and two 
broods were seen. Pintails were seen principally on the Petownikip Marsh in late 
June, Black ducks were noted only twice, blue-wings once, and baldpates a few times 
in June. Scaup were observed sparingly through the area mostly in June. Golden-eye 
drakes were common in June, and early July, but hens were not common. One brood 
was noted. Both American and red-breasted mergansers were seen regularly and one 
nest was found, 
Banding: 
At least one thousand ducks were banded from mid-summer to October 1. 
Mr. C. O. Bartlett banded 852 ducks (507 blacks, 255 pintails, 68 mallards, 13 hybrid 
mallard-black, and 9 teal): at Moosonee and Cochrane, while L. W. Gray banded 118 
ducks through September 15 with traps expected to remain in operation until October 7 
in the Fort Francis area.
