The Andaman pompadour pigeon ( Treron chloropterus ) is a species of pigeon birds. It occurs on some Southeast Asian islands. It has long been considered a subspecies of the Andaman green pigeon , but the differences to this species are so pronounced that it is consistently recognized as an independent species.
The population of the Andaman Pompadour pigeon is indicated by the IUCN as near threatened , as the population is steadily declining.
Appearance
The Andaman Pompadour Pigeon reaches a body length of 27 centimeters. It is a medium-sized, compactly built pigeon with a powerful beak that is slightly smaller than a laughing pigeon . The gender dimorphism is only slightly pronounced. The main difference between the two sexes is the color of the coat.
The front of the head, the crown and the nape of the neck are gray, the reins and the narrow stripe above the eyes are olive-colored. The rear neck is dark olive, the coat is pale chestnut brown in the males. In the females, however, the coat is green.
The small wing covers are olive colored. The top row of feathers in the middle wing-coverts is dark olive-colored with bright yellow edges. The large elytra are black with sulfur-yellow edges on the outer flags. The arm wings are black and also have yellow edges. The wings are black with narrow yellow or white borders. The back is dark olive, the rump is lime green. The middle control springs are bright olive, the other control springs are olive to gray on the top. A wide pale gray end band runs over the control springs.
The chin, throat and front chest are matte olive in color. The breast then changes to a gray-green. The belly is the same color. The thighs are dark gray-green and usually have broad yellow hems. The under tail ceilings are brick red. The control springs are black on the underside with a wide pale gray end band. The iris is pink with a pale blue outer ring. The narrow orbital ring is blue. The wax skin and the base of the beak are greenish gray, the tip of the beak is bluish horn-colored. The feet are brick red.
Distribution area
The distribution area of the Andaman green doves are the Andamans and Nicobars . The Andaman Islands are located about 300 kilometers south-southwest of Cape Negrais on the western tip of the Irrawaddy Division of Myanmar (Burma). The main islands are North , Middle and South Andaman Island (which are also the main islands of Great Andaman ). The southern end of the island chain is Little Andaman . The total area of the islands is 6,408 square kilometers. The Nicobar Islands are located over 100 km south of the Andaman archipelago, over 600 km west of Malaysia , around 200 km north of the Indonesian island of Sumatra and over 1300 km southeast of the Indian subcontinent .
The Andaman pompadour pigeon is comparatively common in the south of the island chain. On the Nicobar Islands, where it is hunted relatively heavily, it is much rarer. The habitat are moist evergreen forests of the lowlands. It occurs in both primary and secondary forests.
Way of life
The Andaman pompadour pigeon occurs predominantly in small flocks of up to a dozen individuals. Larger groups can also gather on very rich fruit-bearing trees.
The food spectrum includes a very wide range of fruits, berries and buds. Figs, which the pigeons usually peck directly from the branch, play a special role in the diet. This pigeon comes to the ground mainly to drink.
The breeding season in the Andaman Islands falls from February to June. As is typical for pigeons, the nest is a loose platform made of small branches. The clutch consists of two eggs. Both parent birds are involved in the incubation of the eggs. The nestlings hatch 12 to 14 days after the start of breeding.
