Possible confusion

There are several other pigeon species in the distribution area of ​​the Rosakopf fruit pigeon, with which it can be confused.

The bronze fruit pigeon is larger and has a monochrome gray head and neck, which contrasts strongly with the otherwise shiny green upper plumage. The slate-back fruit pigeon occurs like the pink-headed fruit pigeon in Timor and weather. It is a mountain-dwelling species with a gray crown and gray ear-covers that stand out against the wine-red breast. The under tail-coverts are pale cinnamon and not darker than the belly. The beak is black, the legs are black-purple. The black-backed fruit pigeon is also a type of mountain forest. It has a gray parting, which stands out strongly with the wine-red ear covers and the wine-red neck. The under tail coverts are the same color as the belly. The tail plumage has a pale gray end band. The white-eyed fruit pigeon is significantly larger and has an ash-gray crown and ash-gray ear-covers, the upper side of the body is metallic blue-green and the under-tail-covers are gray.

Occurrence and habitat

The species is found on most of the Lesser Sunda Islands , the Southern Moluccas, and a few other small islands in the Malay Archipelago . The westernmost point of the distribution is the Karimunjawa Islands , north of Java . The southernmost point is the island of Timor , the easternmost the Kei Islands and the northernmost the island Bacan , the only one of the northern Moluccas . On Wetar , the pink-headed fruit pigeon is the most common pigeon on the island. The species is also common on Jampea , Timor and the Tanimbar Islands . The fruit pigeon is not common on Atauro , but it is widespread in wooded areas at altitudes above 250 m. The relatively large pigeon is repeatedly a victim of hunters, which is why it is considered to be potentially endangered, even if the hunting pressure is not present in the entire distribution area.

The pink-headed fruit pigeon is a resident bird . It lives in forests, bushland, mangroves and fields up to an altitude of 1100  m .

Way of life

The pink-headed fruit pigeon lives solitary or in pairs. Only in fruit-bearing trees can groups of up to six individuals gather. She lives exclusively on fruits.

The reproductive biology of this species has not yet been studied.
