Eurasian Collared-Doves are found throughout much of North America in urban and suburban settings with access to bird feeders and other seed sources. In agricultural areas they seek open sites where grain is available, including farmyards, fields, and areas around silos. Though evidence is mixed, they appear to avoid areas with heavy forest cover or extremely cold temperatures, which may help explain their absence from the Northeast.Back to top
Eurasian Collared-Doves eat mainly seed and cereal grain such as millet, sunflower, milo, wheat, and corn. They also eat some berries and green parts of plants, as well as invertebrates.Back to top
Males show females potential nest sites in trees and on buildings, giving a low- pitched, slow koo-KOO-kook call at each site. Nests are usually built 10 or more feet above the ground. In warmer regions, Eurasian Collared-Doves can nest year-round, which may help explain their success as colonizers.
The male dove brings the female twigs, grasses, roots and other nesting materials, which he sometimes pushes directly under her. Over 1 to 3 days she builds a simple platform nest, which may include feathers, wool, string and wire. A pair often uses the same nest for multiple broods during the year, and may renovate old nests.

Eurasian Collared-Doves roost on utility poles, wires, and tall trees in open areas near feeding sites. Mainly ground foragers, they peck at grain and seeds scattered beneath backyard feeders and on feeding platforms, or spilled at farmyards. Flocks of 10 to several hundred doves may gather at prime spots. Although they can feed peacefully in mixed flocks, Eurasian Collared-Doves will also chase off other birds, including Mourning Doves, cardinals, and Blue Jays. The male advertises for a mate with an insistent koo-KOO-kook call from a high perch, repeating the call up to a dozen times in a bout, sometimes starting before dawn and continuing into the night. Calls are followed by a flight display in which the male flies steeply upward, clapping his wings, then descends with tail spread, often spiraling down to the same or a nearby perch. Once a pair has formed, males show females potential nest sites, usually in tall trees but occasionally on buildings. In between these “site visits” the pair vigorously preen each other. Male doves bring females sticks and other material for the simple nest, and aggressively chase away other collared-doves, as well as predators—venture too close and you risk getting hit by a flapping wing. The monogamous pair may raise up to six broods a year; the female can lay a new clutch while young are still in a previous nest.Back to top
Since their introduction into Florida in the early 1980s, Eurasian Collared-Doves have spread rapidly and their population has grown over 13% per year, according to the North American Breeding Bird Survey. They now occur throughout much of the U.S., especially in areas converted to agriculture and urban uses. Partners in Flight estimates a global breeding population of 85 million and rates them 4 out of 20 on the Continental Concern Score, indicating a species of low conservation concern. Both intentional and accidental introductions in North America have likely hastened the species' spread. Studies on interactions between collared-doves and other species have not yet shown a negative impact on populations of native birds, including Mourning Doves. As an introduced species, Eurasian Collared-Doves are not protected from hunting and have become popular game birds in rural areas of the Southeast and Texas.Back to top
