What kind of rabbit is this?

I couldn't get a good picture of it because of the distance and low light (I had to brighten that picture a lot in Photoshop just to see anything).

It doesn't look like an Eastern Cottontail, since it doesn't have a mottled color or white tail - https://i.natgeofe.com/k/58df97a7-5c47-44b8-97c1-cddecd7d4a4f/full-body-cottontail_4x3.jpg

It's a mostly solid dark gray or brown color, and it's quite brazen too. It's been hanging around my house and some of the neighbors' houses for the past week or so, eating grass right out in the open in broad daylight. You can get fairly close to it before it will decide to move, and when it does, it doesn't bolt away like a typical wild animal, it just lazily hops a little ways away and starts eating grass again.

I've lived here my whole life (except from 1992 to 1998), which is a residential street in a small town in Maine, and I've seen skunks, raccoons, woodchucks, squirrels, chipmunks, and moles outside, but this is the first rabbit I've ever seen out there. They don't normally venture into town. Maybe it's not even wild, but rather, an escaped pet.
