through the east-central part of the Province (Humboldt, Lake Lenore) uncovered 
no suitable banding sites with sufficient concentrations of waterfowl. 
Throughout the banding period (July 2 - August 5) strong winds and 
frequent showers interfered with operations to the extent of preventing several 
drives and delaying others. In spite of these difficulties the six-man crew 
banded more than 11,000 birds. This effort included a single drive of 3,080 
waterfowl. More flightless young were banded this year than in any previous one.
