My understanding is that Eurasian doves are not migratory ....They are kind of like pidgeons, only cuter.
I found a map showing the range/distribution when I was looking around at them on the internet (can't find it now) that showed them as year round in much of the southern U.S., a fairly large area in S.W. Cal. and even a spot or two in W. Washington. Even showed some in Alaska.
In much of the north, including E. Washington, it showed them as resident only during the warmer months.
Other range/distribution maps show wide variations in where they are and when, probably because they're expanding so quickly.
Guess I'll just have to look when I get there
