Actually, my first thought was that it was a chickaree, but I convinced myself that it might be one of the two owls mentioned in this thread. Thanks for the additional information. I am not surprised that they compete with birds for food, but I was unaware of squirrel predation on bird nests. I was not aware of the taxonomic/geographical parallel either.
I don't think it is possible to add non-birds to an eBird list, but I agree that it would be helpful to have a category for other animals that are sometimes mistaken for birds.

Tamiasciurus douglasi. The Chickaree or "Douglas"squirrel for those with a weakness for eponymics. They start clucking like this furtively in July and become more insistent as the cone cutting season progresses. I encourage everyone to put these arboreal mammals(all squirrels, not just Chickarees) on their eBird lists.      They share with humans and BIRDS a remarkably high brain/body mass ratio , especially when compared to all the other native mammals. They eat the eggs and nestlings of birds at every opportunity. Gray squirrels and red squirrels compete with crossbills for the seeds of cones. In any given ecosystem squirrels surely have more impact on some bird species than many species of bird in that avian community.        Our native red squirrels also demonstrate the same taxonomic/geographical relationship as birds: Chickaree in the Cascades/Coast Range, Spruce Squirrel in the Blue Mountains; Sooty Grouse in the Cascades/Coast Range, Dusky Grouse in the Blue Mountains, etc..

My phone app thinks this is a Pied-billed Grebe, but I presume that's unlikely, considering it was in the forest canopy and there wasn't a body of water nearby. (The Willamette was about 1/2 mile away.) I have gotten a couple of thoughts from others, but I'd like to know what you all think, if you care to share. Thanks.
