About the Ruffed Grouse

The Ruffed Grouse is the drummer of Michigan's north woods. In April and May, males stand on favorite logs and beat their wings in an accelerating thump that sounds like an old tractor starting deep in the forest — a sound felt in the chest as much as heard. The bird itself is a masterpiece of camouflage: mottled brown or gray with a fanned, banded tail and the black neck ruffs that give it its name.

Grouse thrive in young, regrowing forest — aspen stands above all — which makes northern Michigan some of the best grouse range in the country. In winter they grow comb-like fringes on their toes for snowshoeing and will dive headlong into powder snow to roost warm beneath it.


Diet

BudsLeavesBerriesInsects

Buds and catkins — especially aspen — are the winter staple, clipped from treetops at dusk. The rest of the year brings leaves, berries, clover, and insects, which dominate the diet of young chicks.

Questions birders ask

What's the thumping sound in the spring woods?

A male Ruffed Grouse drumming — rotating his wings against the air (not the log) in an accelerating roll to claim territory and attract hens. Follow it quietly and you may spot him on his drumming log.

Why did a grouse explode from under my feet?

Camouflage is their first defense — they hold tight until the last second, then flush in a heart-stopping burst of wings. It's the classic grouse encounter.

Where are grouse found in Michigan?

Young aspen and mixed forest across the northern Lower Peninsula and Upper Peninsula, with smaller numbers in southern Michigan's larger forests. Ten-to-twenty-year-old regrowth holds the most birds.

Can I see Ruffed Grouse in Michigan in winter?

Yes, in any month. Numbers stay fairly steady from month to month. Winter is often the easiest time to find them, with bare branches, open sightlines, and snow cover concentrating birds at reliable food.

What are young Ruffed Grouse called?

Chicks, and they can make short flights at about five days old — one of the fastest developments of any Michigan bird. Broods stay with the hen into early fall before dispersing.

What do you call a group of Ruffed Grouse?

A covey, though Ruffed Grouse are far less social than the term implies and are usually met singly. What they do have is the drumming log, where a male beats his wings to make a low thumping that carries through the woods each spring.
