Mourning doves are almost invariably monogamous (Stewart and Mackey 1954, Laub 1956, Jackson 1963, Brackbill 1970, Blockstein 1986a). Evolution, through natural selection, has molded strong intricate pair bonds that favor an obligate paternal investment that increases the survival of the species (Laub 1968, Wittenberger 1979 and Tilson 1980). The bachelor male, with his extravagant antics, initiates courtship by firmly striking his feet, one after another, on a branch or the ground to display for the female of his affection (Forbush 1927). After gaining her undivided attention, he then prances and struts around with his neck feathers ruffled, cooing, sometimes picking up twigs or pieces of grass (Suthard no date). As courtship progresses, the nest call is accompanied by a gentle flipping of the wings over the back, opling eyes: mutual winking or blinking, and seductive turning and nodding of the head. During the first note of cooing, he will also quickly flash his tail just enough to show off the white marks on the outer feathers (Goss 1891, Craig 1911). In addition to these gestures, an impressive flight display often follows, where he soars very high, gracefully gliding into spirals to the ground in sweeping curves near the female (Barrows 1912). This continues until the female gives her approval of the partner relationship.
After they mutually find a suitable nest site, the male begins to select nesting material - one twig at a time, carefully testing each for proper weight and strength. He brings the material to the female, who waits patiently at the nest site; she then carefully arranges each twig under or around her body to construct a small loose platform nest. Nest building can take up to a week to complete and although mourning dove nests are flimsy, they are generally firm enough to withstand the required 30 days of use (Gander unpublished) if spring and summer storms are mild. Copulation will soon follow.
Mourning doves have evolved to grow very quickly because the mortality risk is much higher for nestlings than for fledged young - due to weathr extremes and nest predators (Harris et al 1963, Coon et al 1981, Grand et al. 1984, Brown 1989). Babies are usually fledged within 14 days. As the young doves grow, their father assumes a greater role in feeding just prior to fledging and continues to care for them until they are completely independent (Hitchcok and Mirarchi 1984a, Blockstein 1986a). The female is then free to attempt another nesting within a short time span if approriate conditions prevail (Lund 1952, Hanson and Kossack 1963). Doves have a strong homing instinct and will generally return to the same areas they were hatched year after year (Bolckstein 1968a). Many doves are non-migrating and remain all year round within their nest territory (Tomlinson, Dolton, Reeves 1988, and others). Doves are often seen at feeders as lifelong bonded pairs. Mourning doves have the longest breeding season of all North American birds and active nests have been found in every month of the year in the United States (Peters 1961).
