The emerald-spotted wood dove (''Turtur chalcospilos'') is a pigeon which is a widespread and often abundant resident breeding bird in eastern Africa from Ethiopia to South Africa. It also occurs in a belt from northern Botswana west to northern Namibia, and in a narrow coastal strip through Angola to Gabon. This is a species of open drier deciduous woodland and second growth. It is absent from evergreen rainforests and semidesert areas. ==Description== Emerald-spotted wood dove is a small plump pigeon, typically 20 cm in length. Its back, hindneck, wings and tail are pale grey brown, and the folded wings have green metallic patches. There are blackish bands on the lower back and tail. The forehead, crown and nape are bluish grey, fading to pinkish grey on the throat. The underparts are mauve-pink, becoming whiter on the belly. The bill of this dove is blackish with a red base. The sexes are similar, but the female may be slightly duller than the male. The immature has duller green spots and buff fringes to the feathers. When flying, black-billed wood dove is told from this species by its bright chestnut underwings. The call is in three parts: two soft long coos, followed by a series of slow descending coos lasting 10 seconds, and concluding with 4 seconds of rapid coos, which decrease in volume. This species shows some geographical variation in plumage, but differences are clinal, and emerald-spotted wood dove is now considered to be monotypic. 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「Emerald-spotted wood dove」の詳細全文を読む スポンサード リンク
