Oriental turtle dove
|Oriental turtle dove|
|S. o. erythrocephala from southern India with no grey on forehead|
The oriental turtle dove or rufous turtle dove (Streptopelia orientalis) is a member of the bird family Columbidae. The species has a wide native distribution range from Europe, east across Asia to Japan. The populations show variations in the patterning of plumage and have been designated into at least six named subspecies. Populations in the higher latitudes tend to migrate south in winter while those closer to the tropics are sedentary. Vagrants have been recorded in North America. The species is predominantly granivorous and forages on the ground.

The species has a wide distribution with geographical variation in plumage that has led to at least six subspecies being designated. The distributions of many are not disjunct and gradation exists except in some island populations. Some of the populations of Streptopelia turtur that occur on the eastern edge can be very similar in appearance to S. orientalis and in the past the two species have been lumped together.
- S. o. meena (Sykes, 1832) – Eastern Asia, central Asia south to the Himalayas from Kashmir to central Nepal. Winters in India as far south as Sri Lanka.
- S. o. orientalis (Latham, 1790) – From central Siberia to Japan and Korea south to the Himalayas from Assam to Yunnan and northern Vietnam. Winters in South and Southeast Asia. (Includes S. baicalensis Buturlin.)
- S. o. stimpsoni (Stejneger, 1887) – An insular form from the Ryukyu Islands.
- S. o. orii Yamashina, 1932 – Taiwan.
- S. o. erythrocephala (Bonaparte, 1855) – south peninsular India. This form has reddish brown on the head with no grey on the forehead or crown unlike in other forms. The undertail coverts and terminal tail band are slaty grey.
- S. o. agricola (Tickell, 1833) – from Orissa and Bengal to the north east of India and into Myanmar south to Hainan.
The Oriental turtle dove has two distinct migratory northern races, S. o. orientalis in the central Siberian taiga, and S. o. meena in open woodland of central Asia. The differences in the tail patterns of the forms S. o. orientalis and S. o. meena help separate identification in their wintering grounds. The nominate form is described as having a grey tip to the tail and more black in the outer web of the outer tail-feathers, while the meena has a white tip to its tail like the turtle dove and less black in the outer web of the outer tail-feathers. However, these are not consistent differences: both forms can have white or grey tail-bands, and orientalis can have little black in the outer webs of the outer tail-feathers.
This small species is very similar in plumage to its European counterpart, the turtle dove. It is a little larger than that species, particularly in the case of orientalis, about the same size as a collared dove. It shares the black and white striped patch on the side of its neck made of silver-tipped feathers, but the breast is less pink, and the orange-brown wing feathers of the turtle dove are replaced with a browner hue, and darker centres giving a scaly appearance. The tail is wedge shaped, like the turtle dove. The flight is more relaxed and direct than that of its relative.
The calls are different from the purr of the turtle dove. It is a four-syllable her-her-oo-oo. There are significant call differences within the populations as well.
Distribution and habitat
The westernmost race, meena, breeds in the Western Palearctic region. The southernmost populations are resident, but most other birds migrate south to winter in India, the Maldives, and southern Japan. They disperse widely and are known from islands such as the Lakshadweep in winter. S. o. orientalis occurs as a rarity in western Alaska and British Columbia. It is also a vagrant to northern and western Europe and occurrences in Britain tend to gather much attention from twitchers.
The habitat varies but it breeds in well-wooded but open habitats and winters in more open habitats but usually with good tree cover.
The summer breeding season in the temperate zone can be protracted. In southern India, the breeding season is in winter. In display, the male flaps its wing noisily and shoots up before gliding down with outspread tail. Nests take about two days to build with the male gathering material and the female placing it. The nest is more substantial than in some other doves and is placed at mid-canopy height. In Japan, nests built at a greater height tended to be prone to predation. Males were found to incubate in the day and the female by night. Two white eggs, as for all pigeons and doves, are laid in a twig nest in a tree. Incubation begins immediately after the first egg is laid. The eggs hatch in 15 to 16 days and the chicks take about 15 to 17 days to fledge (in Japan). Both parents feed the chicks with crop milk. Multiple broods may be raised and nests built by the pair or by others may be reused.Nest reuse may possibly increase the chances of predation. In Japan the principal predators of nestlings and eggs were crows and magpies and to a lesser extent by cats and snakes.
Parasites and diseases
On Hongdo Island, Korea, migratory doves were found to carry seeds of the exotic ''Achyranthes japonica'' attached to their plumage.
