At first glance, the Eurasian collared-dove looks like a chunky, pale gray mourning dove. The overall color is a chalky or grayish tan, with whitish patches at the end of the tail. The primary wing feathers are dark, contrasting with the lighter-colored inner part of the wing; even at rest, the dark wingtips are noticeable. The undertail coverts are gray, and the tail is square-tipped. There is a black crescent “collar” on the upper back (not a complete "ring"). The song is a three-parted “coo-coo-cook” or “cuh-COO-coo,” often repeated incessantly; the call is a raspy, nasal, descending “heeeewww.”
Length: 11½–12 inches. Larger and stouter than a mourning dove.
Statewide.
Habitat and Conservation
Look (and listen) for Eurasian collared-doves in high trees and on telephone poles and power lines in cities and suburbs, and in agricultural settings where they can feed on grain. They visit birdfeeders, too, where they often drive other birds (including mourning doves and even blue jays) away.
As an introduced species, they are not protected from hunting.
Food
Forages on the ground for seeds and grains, including sunflower, millet, milo, corn, and wheat, at backyard feeders and as spilled grain in stockyards and around silos and in other in agricultural areas. The diet is rounded out with berries and small invertebrates. Hatchling doves consume “crop milk,” a protein-rich, whitish fluid created in their parents’ crops.
Status
Permanent resident; the 398th species to be added to Audubon Society of Missouri’s bird checklist. A Eurasian native, it was introduced to the Bahamas in the 1970s. It expanded to Florida in the 1980s, and it has rapidly expanded its range northwest into North America as far as California and Alaska. Originally native to southern China through India to Turkey, it expanded throughout Europe during the twentieth century.
Life Cycle
Platform nests made of twigs, grasses, and other miscellaneous materials are built in trees or on buildings, usually at least 10 feet above the ground. The male brings materials to the female, and she builds the nest. Though clutches only contain 1 or 2 eggs, there can be 3–6 broods annually, often reusing the same nest. Incubation lasts 14–19 days, and the young fledge after about 17 days.
Human Connections
Previous generations of Missourians witnessed rapid expansions of other introduced, invasive birds, such as the European starling and English sparrow. Our generation witnesses the arrival of this species, which may eventually become just as common as the others.
Ecosystem Connections
The parasitic disease trichomonosis (a bird disease caused by the protozoan Trichomonas gallinae) can have severe respiratory and digestive effects in raptors. Healthy doves and pigeons, including Eurasian collared-doves, rock pigeons, and mourning doves, can be carriers. Raptors can become infected with the parasite when they prey upon the doves.
Biologists are tracking the impacts the Eurasian collared-dove is having on our native species. Some have hypothesized it may eventually assume the niche that formerly belonged to the passenger pigeon, which was hunted to extinction a hundred years ago.
Where to See Species
About 350 species of birds are likely to be seen in Missouri, though nearly 400 have been recorded within our borders. Most people know a bird when they see one — it has feathers, wings, and a bill. Birds are warm-blooded, and most species can fly. Many migrate hundreds or thousands of miles. Birds lay hard-shelled eggs (often in a nest), and the parents care for the young. Many communicate with songs and calls.
