Book Description
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.

Book Description
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.

Book Description
A banding program for mourning doves (Zenaida macroura) was conducted by the 14 Central Management Unit (CMU) States and the U.S. FIsh and Wildlife Service during 1967-74. Banding and recovery records, as well as data from annual call-count and harvest surveys, were subsequently analyzed by a subcommittee of the Central Migratory Shore and Upland Game Bird Technical Committee. This paper presents information on mourning dove habitat, hunting regulations, and harvest in the CMU; distribution and derviation of band recoveries in and from CMU; distribution of mourning dove harvest in Mexico and Central America; chronology of migration; survival and recovery rates; effects of hunting on CMU mourning dove populations; and indirect nationwide mourning dove population estimates.

Book Description
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

Book Description
This report includes Mourning Dove Call-count Survey information gathered over the last 36 years within the conterminous United States. Trends were calculated for the most recent 2- and 10-year intervals and for the entire 36-year period. Between 2000 and 2001, the average number of doves heard per route decreased significantly in the Eastern and Central Management Units. No change was detected for the Western Unit. Over the most recent 10 and 36-year periods, significant declines were indicated for doves heard in the Central and Western Units. Additionally, in the Eastern Management Unit, a significant decline was detected over the most recent 10 years while there was no trend indicated over 36 years. In contrast, for doves seen over the 10-year period, a significant increase was found in the Eastern Unit while no trends were found in the Central and Western Unit. Over the 36-year period, no trend was found for doves seen in the Eastern and Central Units while a decline was indicated for the Western Unit.
