The clutch size is almost always two eggs. Occasionally, however, a female will lay her eggs in the nest of another pair, leading to three or four eggs in the nest. The eggs are white, , long, wide, at laying (5–6% of female body mass). Both sexes incubate, the male from morning to afternoon, and the female the rest of the day and at night. Mourning doves are devoted parents; nests are very rarely left unattended by the adults. When flushed from the nest, an incubating parent may perform a nest-distraction display, or a broken-wing display, fluttering on the ground as if injured, then flying away when the predator approaches it.
