The methods included drive-trapping and use of dogs (a Chesapeake Bay 
Retriever and a yellow Labrador) until August 15. After that date, bait-trapping 
was the main method, although some use was made of cannon net traps. 
Attempts to trap mallard hens on nests were unsuccessful during May 
and June. Practically all of the flightless young and all territorial hens and moutling 
adults were banded between July 13 and August 12, 
A summary of the birds banded is presented in Table I. Females referred 
to as "territorial", were flying hens caught in covered traps (after July 29) on drives 
for flightless young. They were assumed to be with broods and are considered to be 
in the same category as adults trapped on their nesting "territory'' and hens caught 
on nests (as opposed to moulting adults whose nesting areas is unknown).
