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.
Mourning Doves raise three or more broods in a single breeding season. Both parents build a flimsy platform nest of twigs located from 5 to 25 feet up in a tree or bush. Two white eggs hatch in about 14 - 16 days.One egg is laid in the evening, and the second on the next morning.ts flight speed has been clocked at 40-55 mph, but a strong tailwind will result in higher ground speeds, making it a difficult bird for a hunter to hit. The Mourning Dove is from 11 to 13 inches long, with a wingspan of 17 to 19 inches. Weights range from 4.5 to 6 ounces.
