Table 3 gives a four-year comparison and summary of waterfowl broods 
observed in Eastern Washington. The big increase in observed broods during the 
past two summers over the counts of 1947 and 1948 does not indicate a relative 
increase in production. Rather, the favorable change is indicative of increased 
familiarity with the area, and greater returns for the effort expended.
