Not the best picture, but this is the first chaseable Dickcissel in my county in a dozen years. Prior to this bird, there were exactly two photos of this species in the entire county.

Ok, I’m not well versed with Eastern Red-tailed, but this bird had heavy streaking in the breast, and a somewhat straight trailing edge to the wings, and the “hands” show four extend primaries versus five, so I’m retracting my RTHA ID.
FWIW, Yellow-bellied should never really be a default option in CA. They are a significant identification challenge, and are thought to be quite rare in California. They’re almost identical to Western Flycatchers so their real status and distribution is somewhat mysterious in California. Voice is the safest way to identify them to species out west.
I’m not saying I’m correct and I’m not saying this ID is easy. However, there appears to be a clear cut consensus in this thread as to the ID of the bird. Yet, it doesn’t appear that you are convinced, so I’m not sure what exactly would convince you that this is in fact, a Palm Warbler.
Common Greenshank in Del Norte County, CA. This is very close to the Oregon border for anyone who lives up that way.
The photos and videos stink, but this observer, and the other observer referenced in the checklist are very reliable. It's legit.
