@pbie 2. Trends in the Breeding-population Index, 1953-62 

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. 
Te 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 1.)
