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.

U.S. mourning dove population indexes increased by 4% from 1969 to 1970 in the Eastern Management Unit, but declined 2% in the Central Management Unit and 11% in the Western Management Unit. The changes were below the 10-year means, 1960-69, by 3% in the Eastern Unit, 15% in the Central, and 27% in the Western. Regression analyses of the call-count data for 1960-70 indicate a statistically significant downward trend in dove breeding populations in all management units; mean rates of decline were 1% a year in the Eastern Unit, 3% a year in the Central, and 4% in the Western

Nationwide dove population indexes presented in the 1967 Mourning Dove Status Report were obtained by essentially the same data gathering and analyzing procedures as in 1966. A refinement was made in the base year index, using the mean of the 1966 and 1967 readings as the base for all States. There was a slight adjustment in physiologic region boundaries. Data analyses suggest that the 1967 dove populations declined to approximately the 1965 level in all units. Present population indexes in all units are below the 10-year (1957-1966) mean. Long-term trends in population densities indicate that dove breeding populations in all units are considerably below the peak of 1960 and, with the exception of the Eastern Management Unite, are at their lowest level since 1957.
