Which rodent matches the following description: also known as groundhogs or whistle pigs; 16 to 20 inches long; brownish grey; chisel-like teeth; damaging to crops; can be controlled without a permit.

• A. Woodchuck
• B. Meadow Vole
• C. Eastern Chipmunk
• D. Porcupine

Answer: (A)

This description points to the woodchuck, the groundhog. They grow about 16 to 20 inches long, have brownish-gray fur, and possess strong chisel-like incisor teeth used for gnawing and burrowing. They’re well known as crop pests, feeding on crops and garden plants and tunneling underground. In many pest-control contexts, woodchucks on private property can be controlled without a special permit, though local regulations may vary. The other animals are much smaller (meadow voles and eastern chipmunks) or, like porcupines, have distinct features (larger size with quills) that don’t match this description.
