since guitar players are known to be such experts on wildlife I've got some little critter making holes in my front lawn. Noticed it a month ago when I mowed my lawn for the last time of the season. Since then, it has made about 8 little excavations. These do not look like something digging from the surface, but rather from below. I've seen mole (voles?) tracks before, you can see them like veins across the turf. There are none of those, just these mounds of rich black earth with little holes in the middle. very hard to get pictures but I can try to see if I can get some with my mom's ipad.
