ALDEN TOWNSHIP, Minn. — In the woods northwest of Two Harbors, in a thicket of young aspen and alder, Bailey Petersen bent down to inspect a small patch of disturbed dirt.
"Another dusting bowl. And this one has a turd in it!" Petersen exclaimed. "And look, there's another grouse turd ... they are everywhere around here!"
Those little green chunks of feces were of course a good sign to grouse hunters looking for their creators. But they are especially interesting to Petersen, whose day job is wildlife biologist for the Minnesota Department of Natural Resources.
