Thanks for doing this again!
This is a rabbit I saw north of Seattle, Whidbey Island area a few weeks ago. Actually, I saw about 5 of these guys hopping around Langley but they have a distinct yellowish fur on the body with black fur under the mouth, wondering what they're called as they seem pretty unique.
It's almost certainly some variety of domesticated rabbit that escaped and became established in the area. It doesn't look like any of the two native species or the other invasive species, and it's definitely not a hare (jackrabbit).
