The white-crowned pigeon feeds primarily on fruit (4), particularly on the fruits of the poisonwood tree (Metopium toxiferum), strangler fig (Ficus aurea), short-leaf fig (Ficus citrifolia) and blolly (Guapira discolor), although it has also been known to occasionally consume insects and small snails (5). Although often seen flying alone, feeding usually takes place in small groups, and this acrobatic bird sometimes hangs upside down while plucking fruit from the crown of a tall tree (4).
The breeding season of the white-crowned pigeon typically occurs between May and September, although this varies depending on the availability of food and location (3). The nest of the white-crowned pigeon is often situated in a tree or bush in a mangrove, and is little more than a loose platform of twigs (7). Breeding usually occurs in colonies, although sometimes a pair may nest in isolation (5). Commonly, one or two glossy white eggs are laid, and the male incubates the eggs during the day while the female undertakes this task at night (5). Hatching after 13 to 14 days (7), the young are initially fed a diet of crop milk and nothing else for several days. Fledging usually occurs after two to three weeks (5). When food is abundant, the white-crowned pigeon may breed as many as four times in one year (3).
