Moat of these birds were caught by han@ with the aid of a Labrador 
‘retriever, Yarious methods of catching broods were considered, auch as the 
use of baited traps and driving, but were discarded as impractical. Flack 
duck broods are usually scattered widely and if disturbed in any way usually 
head for the closest upland vegetation to hide. Fy means of the dog it was 
found that theee young birde would frequently go several] hundred yards inland 
from the water's edge in op matter of a few minutes, It te felt that the 
experimental use of a retriever thia year demonetrates the practicability of 
this method for catching young ducks in the Northeast where other conventional 
wnethods could not be used. 
From August 15 to September 2, Boyer opermted several traps on the 
maranes in the Sackville area of Few Brounewiek. The following were banded: 
Black duck 10E; pintall 15; green-winged teal 4; blue-winged teal 1356; 
ehoveler 1: wood duck 6, 
Summary 
In the northeastern United States, spring breeding ground and summer 
brood data were furnished by co-operators covering definite sample arese. 
The epring breeding ground surveys in Canada were done by plane and cance. 
Important areas in the Maritimes and eouthern Quebec were covered. The 
eunmer brood production survey was done by cance and on foot by two obeervers 
working together, Inasmuch se this was the firet pear thet most major 
breeding areas were covered, ne over-all comparisons with other years can 
be drawn. For those areas where comparisons were possible the indications 
were that the breeding season wat 4 favorable one.
