We first noticed these doves last week.
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. The male usually incubates the egg during the day, and the female incubates at night. Nestlings, cared for by both parents, fledge in about 12-14 days. The parents continue to care for the fledglings until they are 25 to 27 days old.Mourning Doves are prolific breeders. In warmer areas, these birds may raise up to six broods in a season. This fast breeding is essential because mortality is high. Each year, mortality can reach 58% a year for adults and 69% for the young
