I would add Lesser Goldfinch and Great-tailed Grackle. Starling if you go back to the 50s. Euro-trash Doves probably exceed everything but the latter.

Others to consider are RS Hawk and Anna’s Hummingbird, for which there is good data. Older examples include cowbird and maybe House Finch (I don’t have that info with me).

Would you say that Black Phoebes as a native North American species have had the fastest breeding range expansion into Oregon? The only other one I can think of is Barred Owl. Any more off the top of your head?
