What to Watch for:

Size:

20-25 inches long; tail 15 inches long

Coloration:

Prominent orange teeth, dark brown fur, and a flat, paddle-shaped tail

Where to Watch:

  • Streams, rivers, or ponds bordered by woodlands or small marshes.
  • Near active beaver dams - look for the lodge, a dome-shaped structure 5-6 feet tall and 20-30 feet wide.
  • Look for tree cuttings and "chips" of wood near the shoreline.

What to Listen for:

Tail slaps on the water.

When to Watch:

Beavers are active year-round and most likely to be seen early in the morning or at dusk. You may also see one at night with moonlight. In the winter, look for large holes in the ice on ponds that the beavers use to access the underwater entrance to their lodge. Approach carefully and stay hidden-beaver are shy. Be patient-it may take a long time before you finally see a beaver.
