Average brood size for all species appears to have been favorable, 
Considering the reproduction of the duck population as a whole, the success this 
season was at best equal to the previous year and probably was somewhat less, 
Summary of Summer's Banding Operations 
Banding operations were begun the first of August. The drive trap method was 
employed to capture the flightless ducks. Emphasis was placed upon the banding of 
locally raised birds and of the 489 ducks banded within the period August 1 to 
September 15 approximately 91 percent were of this category. Forty-seven percent 
of all the ducks banded were males. 
Blue-winged teal comprised approximately 88 percent of the total number of 
ducks banded. The relative success experienced in banding blue-winged teal results 
from the adaptability of this species to driving and to the abundance of these birds 
in the State.
