They are on the nest 97% of the time. Especially at night. Mourning Doves sit on their eggs for about 2 weeks, feed the babies in the nest for about 2 weeks and then care for their young for about a month after they've fledged. Both male and female mourning doves share in incubating and feeding their young. I'm sure it will be any day now before you see little peepers.

If the eggs are removed from the nest, the female could have new eggs every three or four days.
