Thirty cygnets and one adult trumpeter swan were banded with colored 
plexiglass bands in addition to the ordinary aluminum bands. This banding was 
done by the writer with the assistance of D. A. Munro and B. Hamm of the 
Canadian Wildlife Service, and M. T. Myers of the University of British Columbia, 
in the Peace River Parklands area near Grande Prairie, Alberta.

Summary 
Aerial and ground surveys, somewhat modified from those of previous 
years, were carried out in British Columbia again this year. 
A cool, wet spring delayed the breeding season. Water conditions were 
favorable for waterfowl throughout the season. 
The number of ducks recorded during the spring ground survey in the 
Cariboo showed a slight increase over 1954. Numbers recorded during the aerial 
survey show a decrease but, owing to changes in survey technique, figures this 
year are not strictly comparable to those obtained previously. 
Numbers of Canada geese in the aerial survey of the Upper Columbia 
Valley in the Rocky Mountain Trench were down about five percent from 1954. 
Nest surveys indicate a successful goose-breeding season in the south Okanagan 
and Columbia Valley regions. 
Mid-summer production surveys showed that the hatch this year was 
somewhat delayed, but that the numbers of both young and old birds had increased 
over those of 1954. Brood averages were also up this year. 
A total of 581 waterfowl were banded in the Cariboo region this year. 
Thirty-one trumpeter swans were banded in the Peace River Parklands near 
Grande Prairie, Alberta.
