Mourning dove population indices, as determined from the nationwide Call-Count Survey, decreased from 1972 to 1973 by 7% in the Eastern Management Unit, by 8% in the Central Management Unit, but increased by 8% in the Western Management Unit. The 1973 indices were below the 10-year means, 1963-1972, by 9% in the Eastern Unit, 6% in the Central Unit, and 4% in the Western Unit. Regression analyses of the call-count data for 1963-73 indicate a statistically significant downward trend in dove breeding populations in all management units; mean rates of decline per year were 1% in the Eastern, 2% in the Central and 4% in the Western Unit.

Nationwide dove population indexes presented in the 1966 Mourning Dove Status Report were obtained, using several important in data gathering and analysis. Data analyses suggest that 1966 dove populations have fully recovered from the 1965 decline in the Eastern and Central Management Units, and partially recovered in the Western Management Unit. Present populations approximate those of the 1956-1965, 10-year means in all units.
