I think the collared dove is quite a different kettle of fish. Their
explosive expansion across the US in a generally northwesterly direction
since first detected in Florida in the mid-1980s closely parallels a
comparable expansion north and west in Europe from their original stronghold
in the eastern Mediterranean. Collared doves have quite amazing powers for
colonization. They managed to locate and settle isolated desert oases in
Arizona and California and, I understand, have landed on boats offshore of
the West Coast. Though it is presumed they originated in the New World from
introductions in the Bahamas, it seems to me that they could just as well
given their explosive expansion across Europe have colonized "naturally,"
much as did Cattle Egrets. If that is the case, they are not an "introduced"
invasive species, but rather a species that for whatever reason has
undergone an explosive expansion under their own power. Perhaps the Barred
Owl is a better analog.

I feel the same way about Mute Swans and also about Eurasian Collared Doves.

Hi all, I was hoping that those with knowledge could please regale me with
all the "records" of "valid" Mute Swans which have occurred in Washington
State. I assume that these "valid" records would all be from the British
Columbia "forever established" population. I have seen at least 14 Mute
Swans in Washington State, both east and west of the cascades, none of which
I would ever feel good about counting as anything, let alone a state bird.
Why would a Mute Swan seen in a county close to British Columbia be any more
"valid" than the dozens and dozens seen further afield? When close to BC,
how do you decide which is from the "forever countable" BC population and
which is just like all the other uncountables in the rest of Washington
State. You can't, period. I hate when I enter Mute Swan on e-Bird "just for
the record" and I get credit for a state bird. I might as well mention now,
that all the places I have seen "countable" Bobwhites in Washington State,
I've also seen hunters actually hand releasing live Bobwhites to train their
dogs. Yes, some of you have counted a state bird, perhaps a lifebird, that
was not much more than a recent release; perhaps as little as a day in the
wild in its entire life. Even in the more "remote" places that Bobwhites
"self-sustain" in our state, just how many are actually self-sustaining and
not being propped up by yearly releases and their offspring infiltrating
from every side?
