And I noted three different Wilson's Warblers reported in eBird this week, quite an unusual occurrence to go along with the Western Tanagers that are wintering.

We've had multiple (often two at once) Townsend's Warblers coming to our suet, bark butter, and even seeds for quite a few winters now, since at least 97-98 (we moved in in 1991).

I tacked Townsend's Warbler on to illustrate that some short-distance migrants that summer in the PNW are now staying in the PNW in winter in larger numbers. This is described in the text. So I agree with your point.
