Abstract: An index to the 1963 mourning dove breeding population was obtained by a call-count survey conducted throughout the United States. Trends in the breeding population index were calculated for three management units and for hunting and nonhunting States within the management units. Trends in the breeding population indexes from 1962 to 1962 were as follows: Eastern Unit down 3.6 percent, Central Unite down 1.7 percent, and Western Unit up 3.8 percent. For the United States as a whole, the 1963 breeding population ws down 0.8 percent from 1962. Summaries of call-count surveys conducted in Canada during 1962 and 1963 are included. |
