Book excerpt: U.S. mourning dove population indexes declined from 1968 to 1969 by 2% in the Eastern Management Unit and 8% in the Central Management Unit, but remained unchanged in the Western Management Unit. The changes were not statistically significant. The 1969 indexes were the lowest in the 11-year period 1959-69 and were below the 10-year means, 1959-69, by 8% inthe Eastern Unit, 15% in the Central, and 21% in the Western. For the three units combined, the 1969 index was 5% below that for 1968 and 15% the 10-year mean. Regression analyses of the call-count data for 1959-69 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, 4% a year in the Wester, and 3% a year for the U.S. dove population as a whole.
