Emerald-spotted Wood-Dove
Turtur chalcospilos
A small, dainty, pinkish-fawn, ground-dwelling dove with an all-dark bill and two rows of iridescent green spots on the wing. In flight it reveals bright rufous wings and three gray bands: two across the back and one across the tail. A common but inconspicuous resident of drier savanna and thickets. Melancholic song is similar to that of other wood-doves. The similar Blue-spotted Wood-Dove differs by having a reddish bill with yellow tip, by having iridescent blue spots on the wing, and by preferring moister wooded habitats.
识别特征
The 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.<p>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, the black-billed wood dove is told from this species by its bright chestnut underwings.<p>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.<p>This species shows some geographical variation in plumage, but differences are clinal, and emerald-spotted wood dove is now considered to be monotypic.

行为
The emerald-spotted wood dove builds a flimsy stick nest in a tree or shrub, and lays two cream-coloured eggs. Both sexes incubate for 13–17 days to hatching, and feed the squabs for 13–17 days to fledging. Many young birds are taken by mongooses and shrikes.<p>The emerald-spotted wood dove is not gregarious, but flocks may form at waterholes. This species usually forages on the ground for grass and other small seeds.
