Mallard - 50% decrease, approximately, from last year. 
Green-winged teal - About the same as last year. 
Blue-winged/Cinnamon teals - 65% decrease from last year. 
Wood duck - Probably up slightly from last year. 






Table 8. -- Brood Counts, 1948-1950

Totals 100% (42) 101% (62) 100% (33) 

Each year represents four counts made within the period from May 19 to July 23. 
Mallard - 50% decrease, approximately, from last year, 
Blue-winged and Cinnamon teals ~ Down approximately 65%, 
Wood duck - Up from last year, when no wood duck broods were 
seen on the census plots, 
It is realized that the samples, although fairly large in area, are too small 
to provide adequate information on the thinly distributed breeding population in Western 
Washington. This year, additions have been made to all sample areas, so that compari- 
sons will be available for the 1951 season. 
From the information available, it appears that mallards are off between 40 
and 50 percent, wood ducks have increased somewhat in the northern part of the region 
but are down elsewhere, and blue-winged teal and cinnamon teal are down considerably 
from last year. All species of ducks taken together are down between 45 and 50 per- 
cent from last year. 
Success of the Season 
From an examination of Table 9 it can readily be seen that there is no 
significant change in brood sizes during the last three years from counts made all 
over the state.
