in 1954. These figures are shown in Table II. What the table does not show is 
that in 1954 the transects were flown three times and only four broods were seen 
while in 1955, with only one flight over the transects, seven broods were seen. 
Table II also shows much better brood success for 1955. There were also more 
young and larger average broods for both black and wood ducks, although the 
number of broods of blacks was below one five-year average. 
Banding Operations 
As noted in the introduction the writer, who is also in charge of banding, 
was in Labrador all summer. Therefore, there was no summer banding in 
Delaware this year.
