The grey treepie, also known as the Himalayan treepie, (''Dendrocitta formosae'') is an Asian treepie, a medium-sized and long-tailed member of the crow family. They are widely distributed along the foothills of the Himalayas in the Indian Subcontinent and extending into Indochina, southern mainland China and Taiwan. The populations vary in plumage and several are named as subspecies. Grey treepies are omnivorous birds mostly thriving among dense foliage and in forests. They sometimes take part in mixed species flocks with laughingthrushes, especially the white-throated. Systematically together working through the hill forests, rhododendrons, oaks and other broad leaved trees, especially in the mornings. ==Description== It is the same size as other ''Dendrocitta'' species and is separated from them by the overall grey colour of the body. The races in the western part of the distribution have a greyish rump and some grey in tail while the eastern forms have a white rump and a black tail. The face and throat are dark and black with a diffuse mask. The body is grey on the underside becoming whiter towards the vent. The back and scapulars are brownish. The crown and nape are greyish and the black wing has a prominent white carpal patch. The vent is rufous and the outer tail feathers and tips of the central feathers are black. The species occupies a large geographical range and has several recognised regional forms that differ slightly from one another for instance in colour and tail length. These include ''occidentalis'' of the western Himalayan foothills (identified by its slightly longer tail), ''himalayana'' from the central Himalayas east into Thailand and Vietnam. A disjunct population, said to have a smaller or narrower bill, is found in the Eastern Ghats of peninsular India, ''sarkari'', that is sometimes subsumed into ''himalayana''. The Southeast Asian races include ''assimilis'', ''sapiens'', ''sinica'', ''formosae'' (the nominate race from Taiwan) and ''insulae'' (Hainan Island). It has been suggested that this species forms a superspecies along with ''Dendrocitta occipitalis'' and ''Dendrocitta cinerascens''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「grey treepie」の詳細全文を読む スポンサード リンク
