Nesting Details
Nesting of the Scheepmaker's Crowned-Pigeon occurs in dense lowland rainforests where they find sturdy branches for building nests. Both males and females participate in collecting twigs, leaves, and other forest materials to construct a platform nest. They prefer elevated spots with a good canopy cover to blend and shield their nests from predators. In regions with public gardens, creating quiet, densely vegetated areas with sufficient ground cover and water sources can attract these pigeons for nesting.
Eggs and Chick-Rearing
Females typically lay a single white egg per breeding season. The incubation period lasts about 28 to 30 days, with both parents sharing the duty of incubation. Once hatched, the parents feed the chick with regurgitated partially digested food, known as "crop milk." The chick remains in the nest for several weeks, developing flight feathers before fledging under the watchful eyes of both parents, who continue to nurture and protect the young until fully capable of survival.
