I know the image quality isn't the greatest, but this is one of
the owls I've seen inhabiting the trees in our back yard. Based on the
identifier tool on this site, my best guess would be a northern screech
owl. Though I'm not 100% certain. It has yellow eyes, vertical barbed
type stripes on the front, and is multiple shades of brown and
white/grey. The stripes are either dark brown or black.

This is the other one I've seen. It appears to be quite a bit different than the other, as it's stripes are soft, horizontal and brown rather than black, it's somewhat smaller, and the face is less defined. I have no clue what this one is.
As far as the calls they have, I am not certain. Though I believe the second one has a mid to high pitched single tone repeating cooing type call - Similar to the second mentioned voice text of the western screech owl. http://identify.whatbird.com/obj/14/overview/Western_Screech-Owl.aspx ("cr-r-oo-oo-oo") but I don't think that's what it is.
I live in Washington state.
Hopefully this is enough information to make a correct ID.
