Abstract: The density Index of breeding doves declined in each management unit between 1967 and 1968 at the following rate: Eastern, 4 percent ; Central, 2 percent ; Western, 13 percent ; and the entire contiguous United States, 5 percent. Regression analyses suggest that the trend in populations has been downward in all units since 1958. Although biased to an unknown degree, data collected in conjunction with the Annual Waterfowl Mail Questionnaire Survey suggest that the harvest in the United States increased 28.9 percent and that dove hunters (who also purchased duck stamps) increased 31.5 percent during the period 1965-1966 through 1967-1968. The increase in harvest was due chiefly to an increase in hunter numbers. |
