〕 }} The ashy drongo (''Dicrurus leucophaeus'') is a species of bird in the drongo family Dicruridae. It is found widely distributed across South and Southeast Asia with several populations that vary in the shade of grey, migration patterns and in the size or presence of a white patch around the eye. ==Description== The adult ashy drongo is mainly dark grey, and the tail is long and deeply forked, There are a number of subspecies varying in the shade of the grey plumage. Some subspecies have white markings on the head. Young birds are dull brownish grey. Subspecies ''longicaudatus'' of India (which includes ''beavani'' of the Himalayas that winters on the peninsula, with one breeding population in central India that Vaurie separates as ''longicaudatus'' in the restricted sense) is very dark and almost like the black drongo although this bird is slimmer and has a somewhat longer and less-splayed tail. It is found in more tall forest habitat, has dark grey underside lacking the sheen of black drongo. The iris is crimson and there is no white rictal spot. Subspecies ''leucogenis'' and ''salangensis'' have a white eye-patch as do several of the island forms that breed further south. The calls are a little more nasal and twangy than that of the black drongo. 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「Ashy drongo」の詳細全文を読む スポンサード リンク
