''Gracula'' is a genus of mynas, tropical members of the starling family of birds. Until recently only two species were recognised, ''G. religiosa'' and ''G. ptilogenys''; earlier still all ''Gracula'' were considered to belong to a very variable species commonly called hill myna. But three additional subspecies of ''G. religiosa'' are increasingly being considered distinct species. This genus has representatives in tropical southern Asia from India, Bangladesh and Sri Lanka east to Indonesia, and the common hill myna, a popular cage bird, has been introduced to the USA. The hill mynas are resident breeders typically found in forest and cultivation. The nest is built in a hole and the usual clutch is two or three eggs. These 25–30 cm long birds have glossy black plumage and large white wing patches which are obvious in flight. The bill and strong legs are bright yellow or orange, and there are yellow wattles on the head, the shape and position of which vary with species. The sexes are similar, but juveniles have a duller bill. Like most starlings, the hill mynas are fairly omnivorous, eating fruit, nectar and insects. Hill mynahs are renowned for their ability to mimic the human voice. It has been claimed that the hill mynah is the best talking bird and the best mimic in the world. ==Species== Traditionally, the Sri Lanka hill myna was considered a subspecies of the common hill myna, but today all major authorities recognise them as separate. Comparably, the Enggano, Nias and Southern hill mynas have traditionally been treated as subspecies of the common hill myna; a treatment still preferred by some authorities. *Common hill myna, ''Gracula religiosa'' *Southern hill myna, ''Gracula indica'' *Enggano hill myna, ''Gracula enganensis''. *Nias hill myna, ''Gracula robusta'' *Sri Lanka hill myna, ''Gracula ptilogenys'' 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「gracula」の詳細全文を読む スポンサード リンク
