What is this bird?

This time I'll try to let everyone respond before posting the correct answer.

What's with the purple tips? Is this an Oregon bird?

My guess is that the purple tips are a prismatic effect (akin to hummingbird gorgets). It is an Oregon bird.
 
I see the purple tips as the strong sun shining through dark brown feathers...that said I can'd think of a single bird with under tail coverts like that apart from B&W warbler...and wouldn't that show white tail spots?
 
Mangrove Cuckoo? In Oregon? Hmm...

Whatever the case, can't remember Mangrove, Black-billed or Yellow-billed Cuckoo ever showing undertail coverts mottled in black and white. Not completely sure about juv. Black-billed though...

Looking at the photo again... Could be, that it isn't even undertail coverts, but actually still growing tail-feathers...?

It seems my hint has led you farther astray. I mean I would love to see a "Mangrove Cuckoo" in Oregon, but that is not happening anytime soon. I meant to convey that the mystery bird is closer in size to a Cuckoo than a Warbler. And just about the opposite of a Mangrove Cuckoo in terms of being rare in Oregon.
