Looked like he had a chunk taken out of him at some point. Seems to be fine now.
Pictures aren't great because I didn't want to get too close (skunk in middle of photo). It was definitely a skunk and it looks like there is only 1 skunk species in Idaho.
It didn't seem to notice us, though we were being pretty quiet. When I heard it at first I thought it was a grouse or something. Nope.
Saw the bird fly out of pine needles on the ground and started chirping furiously at me. Turns out it had flown out of a nest. Tiny baby birds!
