Success Of Single-Parent Mourning Dove Nests

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 adult.
