2. Cover was good for both nesting and rearing of broods. 
3. Production appeared below that of previous years as of July 25. Mallard 
broods were 76 percent below 1952 and 47 percent below 1953 as of this 
date. By August 12, all species showed a remarkable increase in numbers 
of broods, 120 percent above the July 25 figure. Unfortunately, there were 
no August data for previous years to make a comparison. 
4. The season was phenologically at least two weeks later than normal for 
most species. Pintails appeared about normal. 
5. Early brood sizes appeared slightly smaller than previous years, those 
of the divers during the August counts appeared about average. 
6. Coot showed an increase of about 50 percent throughout District 8. 
7. It is felt that an extended survey period for the ground studies, through 
August 6, at least, would enable these crews to present a more accurate 
figure for the production index.
