Wallace's fruit dove

Wallace's fruit dove was described as Ptilonopus Wallacii by the English ornithologist George Robert Gray in 1858 on the basis of specimens from the Aru Islands acquired by the British naturalist Alfred Russel Wallace. The species' generic name comes from the Ancient Greek ptilon (feather) and pous (foot), while the specific name wallacii is in honour of Alfred Wallace. Wallace's fruit dove is the official common name designated by the International Ornithologists' Union. Other common names for the species include Wallace's fruit pigeon, Wallace's green fruit dove, golden-fronted fruit dove, yellow-fronted fruit dove, golden-shouldered fruit dove, and crimson-capped fruit dove. It has no subspecies. == Description ==

Wallace's fruit dove is a large, long-tailed fruit dove with a length of . It has been described as "one of the most beautiful" fruit doves. The forehead and are dull crimson, sometimes extending to the back of the neck, and the lower face and throat are white. The rest of the head, neck, breast, and upper are pale bluish-grey, separated from the orange belly patch by a white band. The shoulder patch is golden-bronze, while the mantle and inner are bluish-grey with yellow edges that give a scaled appearance. The and are dark shiny green, the latter having narrow yellow edges, while the back, , and are yellowish-green. The and are mixed pale yellow and green. The central tail feathers green with a whitish band at the end, while the outer ones are darker with a greyish band. The iris is light red with a yellow to green inner ring, the orbital skin is bluish, and the feet are purplish to pinkish. The bill is yellow-greenish yellow with a paler tip. Females are similar to males, but have a greenish tinge to the grey on the neck and breast and a less intense orange belly patch. Juveniles have green edging on the crown, yellow-tipped green feathers on the mantle and wing coverts, and a green wash on the breast and mantle. The beautiful fruit dove (P. pulchellus) looks similar, but is smaller, more compact, and has a shorter tail, with a purple instead of white band, less extensive red on the head, and orange-yellow undertail coverts. The are unmarked deep green. The rose-crowned fruit dove (P. regina) is also similar, but is smaller and more compact with a less extensive pink or pale greyish-purple crown patch bordered with yellow, a pale purple patch separating the breast and belly, rusty-orange undertail coverts, and a well-marked yellow band on the tail. The species is usually silent, but has been recorded giving a loud, melancholy oooo... ooo ooo ooo, with the longest pause between the first and second note. A short woo is also made in excitement. A pigeon on Tanimbar presumed to be from this species was recorded making a repeated hooooow-huwuu, hoooow-huwuu, with the second note slightly shorter and higher-pitched. == Distribution and habitat ==

Wallace's fruit dove is found on the Babar Islands and Tanimbar Islands in the Moluccas, on the Banda Islands, Kur, Manggur, Taam, Komeer, Bacar, Tual, and Kai Kecil in the Lesser Sundas, and the Aru Islands. On New Guinea, individuals have infrequently been recorded in the southwest from the Mimika River to the Noord River, but these are thought to have been vagrants from the Aru Islands. == Behaviour and ecology ==

Wallace's fruit dove is frequently seen alone or in pairs, although it is a social fruit dove and forms flocks of 5–26 birds. On Tanimbar, it is easily noticeable, often flying over roads and clearings or perching in open trees. == Status ==

Wallace's fruit dove is listed as being of least concern by the International Union for Conservation of Nature (IUCN) on the IUCN Red List due to its sufficiently large range and lack of significant population decline. It is fairly common on Tanimbar and the Aru Islands and moderately common on the Kai Islands. It was not seen on the Banda Islands and Taam, where it was formerly common, in 1971. Its survival on highly populated islands indicates an ability to adjust to disturbed habitats. == References ==
