Table 3*—Trends in the breeding-population index, 1957-64 
The first figure listed for each State by years is the 
adjusted average doves heard calling per route. The method 
of adjustment is described in the text. The base year for 
adjustments was 1956 or 1957* States for which 1957 was the 
base year are those that reorganized call-count routes in that 
year. These States are Alabama> Georgia, Kentucky, Mississippi, 
North Carolina, South Carolina, and Tennessee. 
The second figure for each State is the breeding-population 
index. The index, expressed in thousands, is the product of 
the adjusted average doves heard per route and the estimated 
area of dove habitat. (Habitat area is given in table l). 
Data for the years 1953 through 1956 may be obtained from
