I had very good looks at what I can only say was a Lucy's Warbler in my backyard in a tree near the feeders - not on a feeder. It was a small, plain gray warbler with a slim dark bill. Overall warbler type of appearance and shape and behavior as it perched for a few seconds checking out the action at my busy feeder packed with birds including many juveniles. There was no eyering and I didn't note any variation of shading overall in the bird - especially around the eye - no eyebrow - no wing-bars. Was definitely not a gnatcatcher. I did not notice a pale eyeline but I was too shocked to note many details over the 5 seconds I looked through my bins out the window. The face was pale but the head was darker on top which may have been the rusty patch but I did not see this color as it was facing me. Nor could I see the rump in this position.
Then, of course, my "yard" crow called, made a landing on my pergola and everyone scattered. (By the way, this crow has taken at least one baby bird from my yard to eat!) I have not seen the warbler since, but I am staying in my backyard to see if it comes back. I don't get many warblers in my immediate backyard trees except and an occasional stop-by like this one or in migration. But they sing and breed in the park forest behind my house. I came outside, where I am now, and also was sure I heard it sing in response to a "call" playback from my phone from those trees. It was a song that matched a Lucy's Warbler on xeno-canto and is one that I have not heard before from my yard. But no further appearance - yet. Dang - wish I had a picture to show but I'm not hopeful of a return unless someone has a suggestion on what might attract it. I already have lots of seed feeders, suet feeders and hummingbird feeders.
In other news, I saw seven dead Common Murres carcasses in one mile of beach walking - mostly days old and well eaten but one fresh that was washing in with the tide. Also three live ones feeding in the Nehalem River and bay. And about 40 mixed shorebirds - mostly Western.
