The Japanese Wood Pigeon (Columba janthina) has three subspecies.
Black wood pigeons are resident birds. Sexually timid and unapproachable. It is a social bird that gathers in small groups of 20 or 30 birds. Due to environmental damage, the population is endangered, and only smaller groups or pairs or even individual pigeons can be seen. It is a very cautious pigeon that lives almost entirely arboreal and spends most of its time hiding in the leaves of tall trees. If it takes off, its wings will generate great power, and the flight will be agile and fast. It will stand at a certain height and make a call, which is a long oo-woo sound and a bleating call during courtship. It mainly feeds on fruits and seeds of camellia and other plants.
The breeding season is from May to July. Breed in pairs. Nest in a tree, tree hole, or cave. Each litter lays 1 egg. The size of the egg is 42 x 31 mm. The egg is white in color and smooth without spots.
The global population size of the black pigeon has not been quantified, but the species is described as uncommon. Trend demonstration: No data on population trends; However, the species may be declining due to habitat degradation and hunting. While still relatively common on the Japanese island of Izu, it has been significantly reduced there since the 1950s, and is thought to have decreased on Okinawa in the 1980s due to forestry activities. It is estimated that there are only 30-40 individuals of the subspecies on Ogasawara, but the status of the subspecies on the Ivo Islands remains unknown (2005).
