s and pigeons.

Names

Both the names Oriental Turtle Dove or Rufous Turtle Dove have been used for this species. It has been suggested that the name Rufous Turtle Dove should be used for the western form meena, and Oriental Turtle Dove for the nominate orientalis.

Taxonomy

Oriental Turtle Dove has two distinct migratory northern races, S. o. orientalis in the central Siberia

Comprising the central and eastern portion of the Russian Federation, it was part of the Soviet Union from its beginning, as its predecessor states, the Tsardom of Russia and the Russian Empire, conquered it during the 16th...

s of Turtle Dove are replaced with a browner hue, and darker centres. The tail is wedge shaped, like the Turtle Dove. The flight is more relaxed and direct than that of its relative.

Differences between the forms orientalis and meena

Differences in the pattern of the tail in the forms S. o. orientalis and S. o. meena have been widely reported (orientalis having a grey tip to the tail and more black in the outer web of the outer tail-feathers, meena having a white tip to its tail like 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.

Vocalisations

The call is quite different from the purr of the Turtle Dove. It is a four-syllable her-her-oo-oo.

Status and distribution

The westernmost race, meena, breeds just into the Western Palearctic region.

Southernmost populations are resident, but most other birds migrate
Bird migration

listed around 30 records, mostly in autumn and winter. Prior to this, it had been suggested that European records referred to escapes from captivity, because of their tameness, the distance from the species' normal breeding range, the suburban habitat of many of the records, and their winter timing; Hirschfeld presented counter-arguments to all these points, and today it is generally accepted that most if not all Rufous Turtle Doves in Europe are wild birds.

 reviewed the British records of this species and concluded that three of the eight accepted records should no longer stand. Oriental Turtle Dove has occurred a number of times since, including a well-watched bird in Oxfordshire in February 2011, which was found in a birdwatcher's garden. The house owner used the opportunity to charge a £5 fee to view the bird from his kitchen window and up to 500 people queued to see the bird.
