Eurasian Collared Dove

The Eurasian collared dove has been extensively studied due to its amazing ability to rapidly colonize new territories. The Eurasian collared dove is considered an invasive species in much of its territory. With a global population estimated between 60 and 110 million individuals worldwide, and the ability to disperse hundreds of miles in each generation, this dove is an incredibly effective colonizer.

This collared dove, Streptopelia decaocto, is similar to several other doves with collars or rings on their necks. The European turtle dove, Streptopelia turtur, and the Barbary dove, Streptopelia risoria, are in the same genus.

The expansion of the Eurasian collared dove is concerning because it is an aggressive competitor and highly territorial. After being introduced in the Bahamas in 1970, the dove took up residence all over the Caribbean and throughout much of North America and Central America. As of 2026, the Eurasian collared dove has reached Trinidad and Tobago and is being monitored for potential expansion into South America.

Incredible Eurasian Collared Dove Facts

• This dove spread from the Caribbean across most of the United States and into Canada in just a few short decades.
• The expansion of this species in Europe has been described as exponential.
• The name of the Eurasian collared dove’s genus means “collared dove” and includes several species, all with dark rings or collars on their necks.
• These doves are aggressive and territorial. They will attack other birds, ripping out feathers and pecking them viciously. They will even attack much larger crows in defense of their nests.
• Eurasian collared doves mate for life and work together to raise their young. Their offspring are driven by an urge to fly as far as possible before finding mates of their own.
• Mutations cause at least two variant colorations of the species: the Ino mutation results in a white to blond bird, and a less common mutation causes brown plumage.

Where to Find Eurasian Collared Doves

The Eurasian collared dove originated in what is now Bulgaria. This dove was first described by the Hungarian naturalist, Imre Frivaldszky, in 1838. It is not known how or when precisely the bird first arrived in the Balkans. It remained there for some time before beginning a rapid dispersal across Europe and Asia.

This determined dove made it all the way to Africa on its own. It now has populations in Morocco and Egypt, and perhaps other countries in the northern portion of the continent.

The journey to North and Central America required a bit of human assistance. It began in 1970, when a pet supplier in the Bahamas imported a few breeding pairs from the Netherlands. In 1974 several of the birds were accidentally released during a robbery, and the supplier subsequently turned the rest of his stock loose. An estimated 50 or more Eurasian collared doves were then free and breeding in the Bahamas.

In an almost frightening display of expansion, the birds took only a few short years to spread from one island to another throughout the Caribbean. By the early 1980s, the doves had taken hold in Florida.

Today, the Eurasian collared dove has spread to dozens of countries, including those in Europe and Asia. Its range now covers most of the United States, into Canada, throughout the Caribbean, and into Mexico. In 2020, the species was officially listed as present in Trinidad and Tobago. Researchers are watching carefully for the expansion of the species into South America from there.

Classification and Scientific Name

The scientific name of the Eurasian collared dove is Streptopelia decaocto. The word “streptopelia” translates to “collared dove.” It is the name of the genus which includes Eurasian and other species of collared doves, including Streptopelia risoria, the Barbary dove, and Streptopelia turtur, the European turtle dove, among many others.

The name “decaocto” was given to the bird in reference to its call. The name is based on an ancient Greek myth about a young servant woman who called out the word in complaint about her poor wages. She was turned into a dove by Zeus so that she could escape her master.

Appearance

The Eurasian collared dove, unsurprisingly, has a mark around its neck. In fact, it was named for the collar and belongs to a genus filled with species of doves with such markings.

The crescent-shaped black collar is rimmed in white, and it stands out against the light gray plumage of the bird. This gray is tinged with pink around the head and breast. The doves are about 12 to 14 inches long and weigh less than half a pound. Both the males and females look essentially the same.

This dove has a tail that distinguishes it from some similar species in that it is squared off rather than pointed. The underside of the tail is white. Adults have red eyes while juveniles have brown. Adults have a black beak and short, pinkish legs and feet. Juveniles look similar, with darker legs and just a bit of reddish color to their feathers. The juveniles also have a less defined collar until they mature.

Two known color aberrations exist within the Streptopelia decaocto species. One is the Ino mutation, which results in a white to blond color. This mutation is also present in Streptopelia risoria. Another rare mutation causes the Eurasian collared doves to exhibit brown plumage.

Behavior

Perhaps the most defining characteristic of the Eurasian collared dove is the process by which the newly independent juveniles disperse from their parents. These birds are known to fly as far as 600 km, or nearly 375 miles, to start their adult lives. This urge to travel so far from their nest of origin is what drives the expansion of the species.

Much like a wildfire, the dispersal of the Eurasian collared dove follows a sort of jump and backfill pattern. Like smoldering embers carried on the wind far ahead of a fire, so are the individual doves making their way as far from home as they can. New territories are claimed, far in advance of the existing population’s range, and the area in between quickly fills in as other members of the species take flight.

The Eurasian collared dove is an aggressive competitor wherever it goes. It will attack other birds and chase them from food sources. It has been observed pulling feathers from rival birds, jumping on their backs, and pecking at them violently. The dove will even attack crows that try to pilfer eggs from its nest.

This dove tends to live close to humans, even nesting on buildings and other artificial structures. They are often found perched high in trees or on utility lines, and they roost together in large colonies.

Diet

Like many other doves, commercial bird feed is a favorite part of the Eurasian collared dove’s diet. They eat grains primarily in the wild, and they have adapted easily to eating from bird feeders.

These doves also tend to live near agricultural areas, feasting on the grain that is spilled or left in the fields. They will eat wild grains, berries, and even small insects.

These doves can eat a large amount of food and store it in their crop. That means they are free to sit on a high perch and avoid predators while they take their time digesting what they have consumed.

Reproduction

These doves reach sexual maturity around the first spring after they become independent. The exact age of the birds at that time can vary because the Eurasian collared dove has multiple broods throughout the year.

The doves are monogamous and mate for life. Each of their broods is typically just 1 to 2 eggs, but they can have 3 to 6 broods each year. Both the male and the female take turns watching over the nest and incubating the eggs. Incubation takes about 14 to 19 days.

Although the Eurasian collared doves are attentive parents, their nests are not well-formed. They are a simple pile of twigs, at least 10 feet off the ground, sometimes in trees or on artificial structures. Eggs and hatchlings often fall from the nests. This may be one reason the birds have so many broods each year.

After hatchlings emerge, the parents feed them with a white fluid they produce in their crops. This fluid is called crop milk. Within another 18 days, the offspring, known as either squabs or chicks, are ready to fledge. They are fully independent about 30 to 40 days after hatching, at which time they tend to disperse far from the nest and begin the cycle again.   

Predators

The greatest predatory threats to Eurasian collared doves are owls, hawks, and domestic cats. These doves feed on grains and are likely to be found around bird feeders put out by humans. They are most vulnerable when they come to the ground to feed.

Crows have been known to take eggs from the doves’ nests. Snakes would also be likely predators if the eggs were left unattended too long.

Eurasian collared doves have a few advantages that would help them to either avoid predators or challenge them. First, the pairs of doves mate for life and work together to incubate eggs. This means they are rarely unattended. The birds are also highly aggressive and territorial, and will defend their young even against much larger birds like crows. Finally, the adult doves can avoid exposure for long periods due to their efficient feeding habits, thus reducing the risk of being attacked.

Lifespan

The longest recorded lifespan of a Eurasian collared dove in the wild is 17 years, 8 months. This specimen, a banded bird in Europe, was found dead. The longest living captive specimen lived around the same amount of time, 17 years, 9 months. The average life span is much shorter, with relatively few of these birds making it past about 5 or 6 years of age.

Concerns over the spread of Eurasian Collared Doves

One of the main concerns regarding the spread of these doves is that they may take up habitat and resources from native birds. Their aggressive nature gives them an advantage at feeders, and their willingness to fight can drive songbirds and even other doves away

Eurasian collared doves are listed as a species of least concern on the IUCN Red List. Their population is estimated at up to 75 million mature birds, and up to 100 million overall. The population is relatively stable in Europe, but is increasing at a rapid pace in other parts of the world, including across the United States.

Another concern is disease. Eurasian collared doves were recently recognized as carriers of West Nile Virus, a disease that can be deadly to humans.

They are also known to carry a parasite called Trichomonas gallinae, a protozoan that causes lesions in the mouth and sometimes the brain and liver of an infected bird. The resulting disease, trichomonosis, can cause a bird to lose weight and eventually die. Sanitation of bird feeders and water sources is necessary to help stop the spread of the disease.

Because Eurasian collared doves are not a protected species, they can be hunted in accordance with local laws. Extra care should be taken, though, to prevent shooting similar-looking native birds, which may be protected species.
