Dusky grouse There it is, a soft, low thumping in the distance. It may not be entirely clear whether you are feeling it or hearing it, rather like a heartbeat in the forest. It can be hard to pinpoint as well, as the sound has a ventriloquist effect that seems to come from different directions. Listen and wander around through, and eventually you are likely to find its source, a hooting male dusky grouse. Dusky grouse, often called blue grouse, inhabit the pine and fir forests of western Montana
