Sorry, I'm a loving idiot. I didn't realize they leave at night usually for both of them to gather food.
Oh, and:
Courtship begins with a noisy flight by the male, followed by a graceful, circular glide with outstretched wings and head down. After landing, the male will approach the female with a puffed out breast, bobbing head, and loud calls. Mated pairs will often preen each other's feathers.[13]
The male then leads the female to potential nest sites, and the female will choose one. The female dove builds the nest. The male will fly about, gather material, and bring it to her. The male will stand on the female's back and give the material to the female, who then builds it into the nest.[18] The nest is constructed of twigs, conifer needles, or grass blades, and is of flimsy construction.[7] Mourning doves will sometimes requisition the unused nests of other Mourning Doves, other birds, or arboreal mammals such as squirrels.[19]
Most nests are in trees, both deciduous and coniferous. Sometimes, they can be found in shrubs, vines, or on artificial constructs like buildings,[7] or hanging flower pots.[18] When there is no suitable elevated object, Mourning Doves will nest on the ground.[7]
The clutch size is almost always two eggs.[18] Occasionally, however, a female will lay her eggs in the nest of another pair, leading to three or four eggs in the nest.[20] The eggs are white, 6.6 ml, 2.57–2.96 cm long, 2.06–2.30 cm wide, 6–7 g at laying (5–6 % of female body mass). Both lovees 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.[18] 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.
Incubation takes two weeks. The hatched young, called squabs, are strongly altricial, being helpless at hatching and covered with down.[18] Both parents feed the squabs pigeon's milk (dove's milk) for the first 3–4 days of life. Thereafter, the crop milk is gradually augmented by seeds. Fledging takes place in about 11–15 days, before the squabs are fully grown but after they are capable of digesting adult food.[19] They stay nearby to be fed by their father for up to two weeks after fledging.[13]
Mourning Doves are prolific breeders. In warmer areas, these birds may raise up to six broods in a season.[13] This fast breeding is essential because mortality is high. Each year, mortality can reach 58% a year for adults and 69% for the young.[20]
The Mourning Dove is monogamous and forms strong pair bonds.[20] Pairs typically reconvene in the same area the following breeding season, and sometimes may remain together throughout the winter. However, lone doves will find new partners if necessary.
