Groundhogs are bad at predicting weather, but they’re valuable animal engineers

Whether you call him groundhog, woodchuck, or whistle-pig, or use the full genus and species name, Marmota monax, the nation’s premier animal weather forecaster has been making headlines as Punxsutawney Phil for decades.

The largest ground squirrel in its range, groundhogs like Phil are found throughout the midwestern United States, most of Canada, and into southern Alaska. M. monax is the most widespread marmot, while the Vancouver Island marmot (M. vancouverensis) is found only on one island in British Columbia.
