Abstract

Pink-headed Fruit-dove Ptilinopus porphyreus is a little-known, restricted-range species, endemic to the mountains of the Indonesian islands of Sumatra, Java and Bali. In the period 1981¿2002 we conducted surveys throughout its range and compiled data on its presence and absence on 32 isolated mountain complexes. The fruit-dove appeared to be restricted to <12,000 km2 of forest, scattered over 20 major mountain complexes on the three islands, i.e. three on Sumatra, 16 on Java and one on Bali. It occurred exclusively on mountains of > 2,000 m in altitude, where, depending on the size of the mountain, it reached its lower altitudinal limit between 500 and 1,000 m. The species was found mostly in singles or as pairs but occasionally in flocks of up to 17 individuals. It occurred almost exclusively in forest, feeding on figs and small berries in the upper-canopy. We documented three cases of breeding in the wild. From captive birds it is known that a single egg is laid which is incubated for 20 days, with fledging occurring after another 15¿16 days. Based on a study of 104 skins, the breeding season peak in West Java is at the beginning of the dry season. Although Pink-headed Fruit-dove is found in scattered, ever-shrinking forest blocks of mostly <200 km2, the scarcity of recent field records is more than likely due to its inconspicuous behaviour, and a threatened status is unwarranted as yet
