The Eurasian Collared Dove (Streptopelia decaocto), called Turkduva in Skåne, most often simply called the Collared Dove, also sometimes hyphenated as Eurasian collared-dove, is a species of dove native to warm temperate and subtropical Asia, and introduced in North America in the 1980s.
In the latter half of the 20th century the species' native range vastly expanded, and it can now be found from Southeast Asia through to Western Europe.
Collared doves are sometimes kept in aviculture, and form strong relationships with each other.
The genus name Streptopelia is from Ancient Greek streptos, "collar" and peleia, "dove". The specific decaocto is a latinisation of the Greek word for "eighteen", from deca, "ten", and octo, "eight". In Greek mythology, a servant complained bitterly about pay of just 18 pieces a year, and the gods changed her to a dove that still cries mournfully.
The collared dove is not migratory, but is strongly dispersive. Over the last century, it has been one of the great colonisers of the bird world, travelling far beyond its native range to colonise colder countries, becoming a permanent resident in several. Its original range at the end of the 19th century was warm temperate and subtropical Asia from Turkey east to southern China and south through India to Sri Lanka.
In 1838 it was reported in Bulgaria, but not until the 20th century did it expand across Europe, appearing in parts of the Balkans between 1900–1920, and then spreading rapidly northwest, reaching Germany in 1945, Great Britain by 1953 (breeding for the first time in 1956), Ireland in 1959, and the Faroe Islands in the early 1970s.
Subsequent spread was 'sideways' from this fast northwest spread, reaching northeast to north of the Arctic Circle in Norway and east to the Ural Mountains in Russia, and southwest to the Canary Islands and northern Africa from Morocco to Egypt, by the end of the 20th century.
In the east of its range, it has also spread northeast to most of central and northern China, and locally (probably introduced) in Japan. It has also reached Iceland as a vagrant (41 records up to 2006), but has not colonised successfully there.

Invasive status in North America
In 1974, fewer than 50 Eurasian Collared Doves escaped captivity in Nassau, New Providence, Bahamas. From the Bahamas, the species spread to Florida, and is now found in nearly every state in the US, as well as in Mexico. In Arkansas (United States), the species was recorded first in 1989 and since then has grown in numbers and is now present in 42 of 75 counties in the state.
It spread from the southeast corner of the state in 1997 to the northwest corner in 5 years, covering a distance of about 500 km at a rate of 100 km per year.
This is more than double the rate of 45 km per year observed in Europe. Interestingly, as of 2012, few negative impacts have been demonstrated in Florida, where the species is most prolific. However, the species is known as an aggressive competitor, and there is concern that as populations continue to grow, native birds will be outcompeted by the invaders.
However, one study found that Eurasian Collared Doves are not more aggressive or competitive than native mourning doves, despite similar dietary preferences.
Population growth has ceased in areas where they’ve been established the longest, such as Florida, and in these regions recent observations suggest the population is in decline. The population is still growing exponentially in areas of more recent introduction.
Carrying capacities appear to be highest in areas with higher temperatures and intermediate levels of development, such as suburban areas and some agricultural areas.
While the spread of disease to native species has not been recorded in a study, Eurasian Collared Doves are known carriers of the parasite Trichomonas gallinae as well as Pigeon Paramyxovirus. Both Trichomonas gallinae and Pigeon Paramyxovirus can spread to native birds via commingling at feeders and by consumption of doves by predators.
Pigeon Paramyxovirus is an emergent disease and has the potential to affect domestic poultry, making the Eurasian Collared Dove a threat to not only native biodiversity, but a possible economic threat as well.

It is a medium-sized dove, distinctly smaller than the wood pigeon, similar in length to a rock pigeon but slimmer and longer-tailed, and slightly larger than the related turtle dove, with an average length of 32 cm from tip of beak to tip of tail, with a wingspan of 47–55 cm, and a weight of 125–240 g.
It is grey-buff to pinkish-grey overall, a little darker above than below, with a blue-grey under wing patch.
• It has a black half-collar edged with white on its nape from which it gets its name.
• The iris is red
• Very similar to the African Collared Dove and other related members of its genus; in much of the range the only likely member to be confused is Barbary Dove, a domesticated form of African Collared Dove
The tail feathers are grey-buff above, and dark grey tipped white below; the outer tail feathers also tipped whitish above. It has a black half-collar edged with white on its nape from which it gets its name. The short legs are red and the bill is black. The iris is red, but from a distance the eyes appear to be black, as the pupil is relatively large and only a narrow rim of reddish-brown iris can be seen around the black pupil.
The eye is surrounded by a small area of bare skin, which is either white or yellow. The two sexes are virtually indistinguishable; juveniles differ in having a poorly developed collar, and a brown iris.
There are two subspecies, Streptopelia decaocto decaocto in most of the range (including all of the 20th century colonisations), and Streptopelia decaocto xanthocyclus in the southeast of the range from Burma east to southern China. The latter differs in having yellow skin around the eye (white in the nominate subspecies).
Two other subspecies formerly sometimes accepted, Streptopelia decaocto stoliczkae from Turkestan in central Asia, and Streptopelia decaocto intercedens from southern India and Sri Lanka, are now considered synonyms of S. d. decaocto.
It is closely related to the island collared dove of southeast Asia and the African collared dove of sub-Saharan Africa, forming a superspecies with these. Identification from African collared dove is very difficult with silent birds, with the African species being marginally smaller and paler, but the calls are very distinct, a soft purring in African collared dove quite unlike the Eurasian Collared Dove's cooing.

Collared doves typically breed close to human habitation wherever food resources are abundant and there are trees for nesting; almost all nests are within 1 km of inhabited buildings. The female lays two white eggs in a stick nest, which she incubates during the night and which the male incubates during the day. Incubation lasts between 14 and 18 days, with the young fledging after 15 to 19 days.
Breeding occurs throughout the year when abundant food is available, though only rarely in winter in areas with cold winters such as northeastern Europe. Three to four broods per year is common, although up to six broods in a year has been recorded. Eurasian Collared Doves are a monogamous species, and share parental duties when caring for young.

The male's mating display is a ritual flight, which, as with many other pigeons, consists of a rapid, near-vertical climb to height followed by a long glide downward in a circle, with the wings held below the body in an inverted "V" shape. At all other times, flight is typically direct using fast and clipped wing beats and without use of gliding.
The collared dove is not wary and often feeds very close to human habitation, including visiting bird tables; the largest populations are typically found around farms where spilt grain is frequent around grain stores or where livestock are fed.
It is a gregarious species and sizeable winter flocks will form where there are food supplies such as grain (its main food) as well as seeds, shoots and insects. Flocks most commonly number between ten and fifty, but flocks of up to ten thousand have been recorded.
The song is a coo-COO-coo. The collared dove also makes a harsh loud screeching call lasting about two seconds, particularly in flight just before landing. A rough way to describe the screeching sound is a hah-hah.
Collared doves cooing in early spring are sometimes mistakenly reported as the calls of early-arriving cuckoos and, as such, a mistaken sign of spring's return.
