I thought that was an interesting question, so took a stab at
answering it by crunching some ebird bar-chart data that I had
available (one caveat is I only looked at pre-2016 US data). After
playing with the numbers a bit, my definition of "most uniquely
Oregonian" turned out to be what one sees more easily in Oregon than
in any other state.
I first queried which birds appear on Oregon lists more frequently
than on lists from any other US state and came up with:
The number of ebird lists that White-capped Albatross, Red-breasted
Goose, Wandering Albatross or Murphy's Petrel appear on is really low,
so I didn't bother with them anymore.
Similarly, the Tundra Bean-Goose was a one season wonder.
The other species seemed like legitimate contenders, so I thought I
would look at how often they appear on the lists of the other states
where they are most frequently reported and compare the percentage of
lists in Oregon with the percentage of lists of the next closest
state. (That data begins below after the next paragraph).
Of species that breed in Oregon, Hermit Warbler is seen almost twice
as often in Oregon as in any other state. Of species that winter in
Oregon, Cackling Goose is seen 1.71 times as often as in any other
state. And of the residents, Northern Pygmy-Owl appears on 1.60 times
as many lists as any other state. Honorable mention in the breeding
category goes to Vaux's Swift (1.73), and to Red-breasted Sapsucker in
the resident category (1.47).

PS: I just wanted to add that this is purely an academic question,
not a political one – nothing to do with our official state bird.

SUBJECT: The most Oregonian bird?
Greetings… I’m new to this list, and had a question.
The recent story about changing the state bird of Oregon got me
wondering – which bird would be the most “uniquely Oregon”?
Ideally, by my measure that’d be a bird with a full-year range
exactly matching the border of Oregon. Since that doesn’t exist,
which is the closest to it?
I was thinking perhaps a Wrentit, or “Oregon” Dark-eyed Junco,
maybe Red-breasted Sapsucker… White-headed Woodpecker… Anyone have
