For what it's worth...
I worked on Old Growth research in the central part of the Oregon Coast Range in 1985-86. We had plots in sort of a rough rectangle bounded by Rice Hill and Roseburg on I-5 and inland 20 mi from the ocean from Coos Bay to Reedsport, We had plots in various ages of timber.
I just went back to my notes of the birds that I recorded on the days that I worked, representing various stands of timber on different days. I pulled data from April 19 - June 30 for both years.
1986 (37 days afield) 19 Black-throated Gray Warbler 293 Hermit Warbler 2 Townsend's Warbler (April 19 & June 19, 1986)
That's all the Townsends I recorded.

Here around Newport Townsend's are uncommon wintering, and regular at least from September to April. However, they seem to be much less common than in the 1970s. Back then I regularly encountered wintering flocks of 20-30 birds, whereas I now mainly see numbers in single digits.
I suspect they like the Sitka Spruce zone here better than the Doug Fir dominated east side of the Coast Range.

I have lived in the Washington County Coast Range for 25 years and seen Townsend's Warbler at best TWICE in all those years. Even spring records at the peak of migration should be well documented in my opinion. When there are scores on Mt Tabor there are zero at my house. I learned about ten years ago that "heard only" Hermit/Black-throated Gray in my immediate area are best reported that way. I have seen enough Hermits singing B-t G songs on Hayward Rd to make me gunshy everywhere I hear either species now.

Subject: Re: Townsend's Warblers in the Oregon Coast Range Date: Wed Jul 5 2017 10:21 am From: celata AT pacifier.com I would not be so bold as to speak for the entire Coast Range, but I can say that in the last 30 years... that's right, I moved to Astoria in 1987.
..in the last 30 years I have chased many claims of summering Townsend's Warblers between Pacific Co and TillamooK Co. I have never been able to verify any because all the (mostly) Hermit Warblers were making far too much noise and doing so with a reckless disregard for what the tapes, CD's and smartphone apps would have us believe Hermit Warblers are supposed to sound like.
...and if they're not Hermits, they are Black-throated Gray Warblers...
I have done the ground work using tape play-back and/or diligent chasing. No Townsend's.
The last of the Townsend's Warblers usually clear out by the end of May and do not re-appear until August.
Listing Hermit Warbler OR Black-throated Gray OR Hermit/BTYW would be reasonable for ebirders, but throwing Townsend's into the mix muddies the waters unnecessarily. I would argue that if a birder is that unsure about what they are hearing they might want to consider warbler sp. (or just pretend like they didn't hear the thing). --
