The gray-fronted pompadour pigeon ( Treron affinis ) is a short-tailed species of pigeon birds. It is widespread in western India. It has long been considered a subspecies of the Sri Lankan Pompadour Pigeon , but the differences to this species are so pronounced that it is consistently recognized as an independent species.

The stock situation of the gray-forehead pompadour pigeon was classified in the IUCN Red List of Threatened Species as “ Least Concern (LC) ” = “not endangered”.

The gray-fronted pompadour pigeon reaches a body length of 26 centimeters. It is a medium-sized, compactly built pigeon with a powerful beak that is slightly smaller than a laughing pigeon .

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.

Distribution area

The distribution area of ​​the gray-forehead pompadour pigeon is the west of India from Bombay to Kerala. The distribution area are the Western Ghats , a mountain range in western India, which runs on the edge of the Dekkan Plateau and separates it from the narrow strip of the coastal plain and the Arabian Sea. The distribution area also includes the Nilgiri Mountains , a side chain of the Western Ghats in northwestern Tamil Nadu.

The habitat are moist evergreen forests. It occurs in both primary and secondary forests and prefers the lower altitudes.

Way of life

The gray-fronted pompadour pigeon occurs predominantly in small groups 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. 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.
