The great Celebes fruit pigeon ( Ducula forsteni ) is a monotypical , large species of pigeon birds. It occurs exclusively in Indonesia. The dark, two-syllable calls of this pigeon species are among the characteristic calls of the Sulawesi mountains .
The population of the large Celebes fruit pigeon was classified in the IUCN Red List of Threatened Species in 2016 as “ Least Concern (LC) ” = “not endangered”.
Appearance
The great Celebes fruit pigeon reaches a body length of about 43 to 40 centimeters. It is thus slightly larger than a wood pigeon . The tail accounts for 16.5 to 16.7 centimeters. The weight is about 510 grams. There is no noticeable gender dimorphism . In the female, only the gray areas of the plumage are a little darker.
The plumage on the front of the head and throat is white or very pale light gray, the rest of the head is light blue-gray. The chest is dark bronze green. The belly is white with a pink tint. The under tail-coverts are red-brown. The top of the body is golden green. The back neck has a coppery sheen and the elytra have a bluish tinge. The control springs are also bronze-green, but each spring has a broad, smoke-gray band in the middle, which is narrowly lined with black. The under tail coverts are maroon. The beak is black. The iris is yellow inside and red outside.
Possible confusion
The Celebes pigeon-tailed fruit pigeon is significantly smaller and has a purely gray underside. The bronze fruit dove occurs in the entire distribution area of the large Celebes fruit dove. However, it clearly differs from this in the red-gray color of the head, neck, chest and lower abdomen. The gray ribbon is also missing on the control springs.
distribution and habitat
The greater Celebes fruit pigeon is an endemic species of the islands of Sulawesi and Taliabulu . It inhabits primary and secondary forest of the foothills and mountains at altitudes between 220 and 2000 meters. The altitude she prefers, however, is between 1000 and 1500 meters.
It is a partly common bird in Sulawesi. It is only rare at the upper and lower end of its range. It is rare on the island of Taliabu, east of Sulawesi, where it was only discovered in the 1990s.
Way of life
The great Celebes fruit pigeon lives solitary or in pairs. If individual trees bear abundant fruit, however, there may occasionally be larger gatherings of this pigeon species. It is most commonly seen when flying above the treetops. If it sits in the treetops, it can hardly be made out due to the color of its body plumage. On their foraging, however, they occasionally come to the edges of the forest, where they then sit in lower trees and are easier to spot.
The reproductive biology of this species has not yet been studied.
Dedication name
The specific epithet Forsten is reminiscent of the late Dutch scientist Eltio Alegondas Forsten (1811–1843), who from 1838 until his death in East Asia mainly collected exhibits of local flora, but also sent zoological exhibits to his clients.
