Considered an exotic, non-game species in Texas. Supposedly came from escaped birds in Bahamas to Florida and moving west. They are larger than the native Morning and White Wing doves, almost 2-3 times in size. Some reports state that in high populations they are territorially crowding or chasing out the natives. They do not appear to migrate. Similar residual habits to pigeons.
Observed as aggressive to natives at feeders or feeding areas. Can produce 2-4 clutches per year. Sloppy nest builders. Easily identified by sight, very light tan all over, appears light grey at a distance versus two colored native doves, along with the black collar around the neck.
If you don't see them, you will definitely hear them. Native doves have a two note coo, collards have a three note coo - same as natives first two notes, followed by a third down note. The other unmistakable sound trait is when landing, they emit a grating, screeching sound. Where as native doves will have that single whistling sound, the collards screech.

I've had just one of these birds come to my backyard for a couple years now. At first, I thought it was an albino mourning dove - until Resin clued me in. They're a little bigger than a mourning dove & have a black half-ring around their necks. This bird is aggressive & beats up on the mourning doves. It will chase them & knock them off the wires. I give it a negative rating because it's mean & it's also a non-native bird.

We've seen them in our yard, never at the feeders though, the last two Marches. I've heard they were territorial during breeding season booting out the natives, so hoped they would move on. But an article on Project Feeder Watch's blog seemed to dispute this. They were seeing numbers of Mourning Doves increase in the same areas Eurasian Collared Doves were found. Interesting. Their numbers were based on Florida only. I'd be interested in seeing how it is across North America.
A friend has them come to her feeders and they feed at the same time as Mourning Doves, no fighting has been seen. We hear them coo-ing at another friend's home.
From my experience, thus far, I don't see them as a "good" or a "bad" bird. As I have been learning in my birding journey, one person's experience with a bird species may not be the same as another person's. Like individuals are different, I suspect the same is true for individual birds. I am hoping to give these birds the benefit of the doubt and that maybe the doves who chase other birds off the feeders, will not necessarily do it at all feeders.
