Eurasian Collared Dove coming to a town near you

The book says: "During the 1600s this Indian species began to expand its range until today it occurs in all of Europe and most of Asia. After introductions in the Bahamas in 1974 and Guadeloupe in 1976 it soon expanded throughout the Caribbean and reached Florida by 1980. It is now expanding into other parts of N. America, reaching New Mexico, Colorado, and Montana by 1997; Oregon in 1998; and Washington in 2000."

This evening there were two "cooing" outside my house here in Yamhill Co. I have now seen them in about six different towns in Oregon. I hope they don't begin competing in some way with our native Mourning Doves, but if they compete with the (also non-native) Rock Pigeon, maybe that will be a good thing.
