I couldn't find a suitable binary group for birds, so I posted 'which
owl?' to alt.binaries.pictures.gardens. A friend sent me photos of
owls in her back yard. What a treat!

Looks like an immature Great Horned Owl to me.

They've got some other pictures of bubo virginianus, but they don't look
anything like the one in the link. They've got some mp3s of owl noises, if
that helps.
