NORTHERN ALBERTA AND THE NORTHWEST TERRITORIES ~- Continued 
The lone drake index in 1958 was 60 percent. This year 
it was only 35 percent which is interpreted to mean that relatively 
few of the total birds seen were attempting to nest at the time of 
the survey. It is possible that this is more a reflection of the 
late season than of a difference in production success for the 
season.
