Banggai Fruit Dove (scientific name: Ramphiculus subgularis), no subspecies.
Cardoves are resident birds, often solitary, rarely clustered. Roost in a tree, good at flying, always stop for a moment before taking off when in danger. The flight is fast and powerful. It is often active in the canopy, especially in the morning and evening, and often lives on the dead branches at the top of large trees, generally rarely going to the ground, usually only when it is necessary to peck on mud and sand. Foraging takes place during the day. It mainly feeds on the fruits and berries of trees and plants, seeds, buds, leaves, etc., but also eats insects and small invertebrates.
The male bird frequently raises his chest to the female bird, nods his head, loosens his neck feathers to show off, and walks in circles. Nest among trees or thickets in mountain forests. The nest consists of a simple platform of twigs, in the shape of a shallow dish, relatively simple, and there is no bedding in the nest. Each brood lays 2 eggs, and some breed twice a year. The incubation period is 14-18 days, and the eggs are incubated by the male and female birds in turn. The young birds are late sex, and the parent birds often use the "pigeon milk" secreted by the crop to raise the young.
In the 2016 census, preliminary estimates of the species population size were in the range of 2,500-9,999 mature individuals. A total of 3,500 to 15,000 are expected. The species is declining at a moderate rate due to habitat loss and degradation. By 1991, human development and logging began in the last remaining areas of its primary habitat distribution, anticipating further encroachment by growers on the forest (2010). Exploration by mining companies may also lead to more habitat loss in the near future (2008).
