A broken sprinkler

Might depend on where you are but I it’s urban it could be a fox, if rural a fox or a badger.

As /u/[email protected] suggests, that certainly looks like sand that has been washed out by water around the hole, so I don’t know whether that’s relevant.

Either way, the hole itself doesn’t look like a badger snuffle hole or latrine, so I’d say fox is more likely.
