I think the eastern form is a likely vagrant to Oregon, so it would be good for us to brush up on how to tell them apart. According to the Dunn and Garrett warbler guide, eastern bird have greener backs, and underparts not so bright yellow but more extensive (western have more white around the vent). Songs are distinguishable, but we may be likely to get non-singing migrants.

I recall rumblings of the Nashville Warbler split about ten years ago. Gabrielson and Jewett had the subspecies "Calaveras Warbler" in Birds of Oregon. I believe the Mark Twain short story was titled "The Celebrated Jumping Frog of Calavereas County."
