The white-bibbed fruit dove (Ptilinopus rivoli) is a species of bird in the family Columbidae.
Subspecies include:[1] [2]
This species can bes found in the Maluku Islands, New Guinea and the Bismarck Archipelago. It is also present in many of the islands bordering New Guinea. Among others it occurs in the Moluccas, the Aru Islands Regency.
The islands on which the white-bibbed fruit dove is relatively common include Buru, Seram and Karkar. [3]
Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. It occurs predominantly on primary mountain forest, but it also inhabits secondary forest in a lower density.
In New Guinea it is typically found at altitudes between 1,000 and 3,260 meters above sea level. On smaller islands such as Aru Islands Regency, however, it can also be found in the lowlands. It is a species that predominantly prefers the tree canopy.
Ptilinopus rivoli can reach a body length of 23.5 to 26 centimeters. [4] It is smaller than an African collared dove, but more compact than this one. Their tail is shorter and rounded. In this species the sexes are dimorphic. The males have a striking purple head cap. The females are almost entirely green feathered. The plumage is predominantly dark green. There is a large crescent-shaped white band on the chest. Depending on the subspecies, this band can also have a yellowish tinge. The color of the belly and the underside of the tail also vary depending on the subspecies. There is an elongated, narrow spot of purple color on the belly. The tail feathers are bright yellow. In some subspecies, however, the belly is also pure yellow and the tail feathers are green. The beak is bright yellow.
Ptilinopus rivoli is a fruit-eating species that picks fruits from the branches, but seldom on the ground. The nest is put together from twigs. The laying comprises two eggs, which is atypical for fruit pigeons native to New Guinea. [3]
