A total of 95 complete broods was seen during the aerial and ground survey 
work. Brood data for 1953 and 1952 are presented in Table IV.

Black duck brood sizes appear to have taken a considerable drop from last 
year which appeared to show exceptionally high production as Mr. Addy's figures 
for 1951 show Class I - 6.5; Class II - 6.2; Class III - 5.4, and all Classes - 5,9, 
for black ducks, which more closely approaches this year's figures. 
Ground Survey Work 
Approximately 100 hours of ground survey work were done in New Brunswick 
and Nova Scotia during the period June 9 to July 31. This work was carried out by 
canoe and outboard, and on foot with a Labrador retriever, 
Ground survey work was designed to obtain data on brood sizes and ages, to 
locate areas suitable for future comparative counts and comparison of aerial and 
ground surveys, and to conduct experimental banding with the aid of a dog. 
As practically all this work was done in conjunction with other duties by the 
writer alone, it was not possible to sample many large areas for direct comparison 
with the aerial survey. However, three areas, where it is felt an accurate compar- 
ison could be made, are outlined in Table V. 
Banding 
The banding data listed in this report cover the period June 9 to September 30, 
Banding of flightless birds, using a Labrador retriever, was carried out as an 
adjunct to the ground survey work from June 9 to July 26. A small number of traps 
was operated for a week in late July and again from September 15 to 30 in Nova Scotia - 
New Brunswick border area.
