Quick answer

Look at the neck and the tail. A Eurasian Collared-Dove is pale gray-buff with a narrow black half-collar on the back of the neck and a squared-off tail with broad white patches. A Mourning Dove is warmer brown with black spots on the wings, no collar, and a long, pointed tail. The calls differ too: the collared-dove gives a three-part koo-KOO-kook, the Mourning Dove a soft, sad coo-OO, oo, oo, oo.

If a pale, chunky dove with a black ring on its neck has started showing up under your feeder, you’re watching one of the fastest bird invasions ever recorded in North America. Forty years ago there were none in the United States. Today they’re in almost every state.

They’re easy to tell from our native Mourning Dove once you know the three things to check.

The three checks

Neck: black half-collar means collared-dove
Tail: square with broad white means collared-dove; long and pointed means Mourning Dove
Wings: black spots mean Mourning Dove
Color: collared-dove is paler and grayer
Build: collared-dove is chunkier and heavier

Side by side

	Eurasian Collared-Dove	Mourning Dove
Color	Chalky light brown to gray-buff	Warm tan-brown, pinkish-buff breast
Neck	Narrow black crescent on the back of the neck	No collar
Wings	Plain, with wingtips darker than the rest	Black spots on the upper wing
Tail	Squared off, with broad white patches	Long and pointed, with black-bordered white tips
Length	About 11½–12 inches	About 9–13 inches, much of it tail
Weight	About 5–6 ounces	About 3–6 ounces
Song	Three-part koo-KOO-kook, repeated	Soft coo-OO, then two or three longer coos
Other sounds	A harsh, nasal hwaah, often on landing	Whistling wings on takeoff

Measurements are from Cornell Lab’s All About Birds. Project FeederWatch puts it simply: the collared-dove has a blunt tail tip, while the Mourning Dove’s long, tapered tail comes to a point. From below, as a bird flies over, that tail shape is often the easiest mark of all.

Listen for them

The Eurasian Collared-Dove’s song is a three-part coo, with the stress in the middle. All About Birds notes it may be repeated up to a dozen times in a row. When excited or alarmed, especially just before landing, it gives a loud, harsh hwaah that sounds nothing like a dove.

The Mourning Dove’s song is the familiar slow, mournful coo: a soft coo-OO followed by two or three louder notes, given mainly by unmated males. Its wings make a loud whistle on takeoff and landing, a sound many people hear before they see the bird.

The free Merlin Bird ID app from the Cornell Lab identifies both by sound.

How the collared-dove got here

The Eurasian Collared-Dove is native to South Asia and spread across Europe in the 1900s. Its arrival in the Americas was accidental. According to Audubon, a few dozen birds escaped from a pet store in the Bahamas after a burglary in 1974, and more were released there afterward.

Early 1980s: reached Florida; breeding was first documented there in 1982
1990s: spread rapidly west and north; reached California by 1992
Today: found across most of North America, with parts of the Northeast still largely uncolonized, according to Audubon

Cornell Lab estimates the population has grown more than 13% a year since the early 1980s, to around 85 million birds. It’s one of the most dramatic range expansions ever tracked, and much of that tracking was done by people counting birds at their feeders through Project FeederWatch and eBird.

Are collared-doves bad for Mourning Doves?

So far, the evidence says no. All About Birds notes collared-doves will chase Mourning Doves, cardinals and Blue Jays away from food, but studies haven’t shown a negative impact.

A 2010 study by Cornell Lab researchers using FeederWatch data from Florida found that where collared-doves became more common, the numbers of four other dove species at feeders rose too, not fell. A 2020 analysis in Biological Invasions found the relationships were either not significant or positive. Cornell’s David Bonter has cautioned that competition could still be a concern where food is scarce in northern winters, so it’s worth continuing to watch.

Legal status

The Mourning Dove is a native species protected under the Migratory Bird Treaty Act, and is also a regulated game bird in most states.

The Eurasian Collared-Dove is on the US Fish & Wildlife Service list of non-native species the Migratory Bird Treaty Act does not apply to. Several states allow year-round hunting of it with a license, including Texas, Florida and South Carolina. For backyard purposes, that means the protections that apply to native birds’ nests don’t apply to collared-doves under federal law, though state and local rules still do.

Other doves that get mixed up

Species	How to tell	Where
White-winged Dove	White stripe along the edge of the folded wing; short, square tail	Southwest, Texas and the coastal Southeast
Inca Dove	Small and slim, scaly-looking, chestnut in the wings; call like “no hope”	Southwest and Texas
Common Ground Dove	Sparrow-sized, rufous wings in flight	Southern states
Rock Pigeon	Bigger and heavier, two black bars on the wing, very variable	Nationwide, cities and farms
African Collared-Dove	Paler, almost ghostly, with white under the tail. Usually an escaped pet (also sold as the Ringed Turtle-Dove)	Anywhere, scattered

Feeding doves

Both species feed mostly on the ground. All About Birds lists millet, sunflower, milo, wheat and corn for collared-doves, taken from the ground or platform feeders. Mourning Doves live almost entirely on seed, which Cornell puts at 99% of their diet. Project FeederWatch notes cracked corn and millet scattered on the ground or on a platform will attract doves.

A low platform feeder with a mesh screen suits doves, juncos and sparrows, and keeps seed off wet ground. Honest drawbacks: it’s open to the weather, so it needs a drainage screen and frequent cleaning; it attracts squirrels, and in some areas rats, raccoons or turkeys; and doves can eat a lot of seed quickly. Offer only what gets eaten in a day. Keeping rodents away.

Common questions

What is the dove with a black ring around its neck?

In the US, almost always a Eurasian Collared-Dove. A very pale one with white under the tail may be an escaped African Collared-Dove.

Are Eurasian Collared-Doves invasive?

They’re non-native and have spread across most of the country since the 1980s. So far, research hasn’t shown them harming native doves.

Which is bigger, a collared-dove or a Mourning Dove?

The collared-dove is heavier and chunkier. The Mourning Dove can look as long, but much of its length is its pointed tail.

How do I tell them apart in flight?

Look at the tail. The collared-dove’s is square with broad white; the Mourning Dove’s is long and pointed. Mourning Dove wings also whistle on takeoff.

Are Eurasian Collared-Doves protected?

Not under the Migratory Bird Treaty Act, which doesn’t apply to them. State rules vary. Mourning Doves are protected.

What do doves eat at feeders?

Millet, cracked corn and sunflower, mostly taken from the ground or a platform feeder.
