Success of I-parent mourning dove (Zenaida macroura) nests was the same as success of normal 2-parent nests, when the nests were disrupted following the eighth day after hatching. The time from hatching to fledging of I-parent nests was the same as the period of parental care for normal2-parent nests, when the nests were disrupted following the tenth day after hatching. Nests disrupted before the eleventh day after hatching, required a longer period of parental care. The age of 2 squabs, which could be successfully reared by 1 adult, coincides with the onset of crop gland regression in the...

Within a study area comprising 6 South Carolina counties and 4 North Carolina counties, mourning dove (Zenaida macroura) harvest characteristics, survival, and population trend were studied. High survival and productivity are the factors responsible for the high mourning dove population on the study area. From 1968 through 1975, the study area had a stable breeding population trend, and productivity equaled or exceeded the productivity necessary to achieve population stability. Adult doves survived at a rate of 43.0%, immatures at a rate of 26.3% Increasing the bag limit for 2 hunting...
