With the season so far advanced there can be little or no change in the 
mallard or pintail situation, although some spoonbill, teal, and ruddy ducks are still 
to hatch. SBroods by age classes show that there are no mallards or pintails in the 
Class 1 or downy state. 
Officer Krentz's transects are located in the same Inventory District as 
those surveyed by Mr. Kiel, but the routes covered are different in all cases. Itis 
therefore of interest to note that Kiel arrived at a decrease of 34 percent, closely 
comparable to Krentz's findings. 
As further evidence of this decrease, two biologists conducting a different 
type of survey (complete coverage of 10 quarter-section blocks in the same inventory 
district) obtained a 36 percent decrease in broods. Both officer Krentz and Mr. Kiel 
agreed that late hatches would not lessen the decrease to any appreciable extent. 
The officers who have assisted the biologists in the task of appraising the 
waterfowl populatior. of this Province are as follows: 
Saskatchewan River Delta: E. Lambert, J. G. Reader, N. McKenzie, 
A. D. Clark, T. E. Iles, G. W. Clark, 
R. B. Beck, B. Bercier, Mr. Azure. 
Delta Marsh: W. L. Newman, D. J. McIntosh, C. Batten, 
R. Ward, L. O'Niell. 
Netley Marsh: T. H. Schindler, G. Shand, T. L. Couture. 
Southwestern Manitoba: H. Krentz, R. Gilmore, J. Serafin, 
G. Parsons, W. J. Goodey, H. F. Henderson.
