Indicators are solid for an upturn when Minnesota's grouse season opens

Brainerd – Many hunters consider ruffed grouse to be the king of game birds. That means Saturday is a big day: the 2017 Minnesota hunting season on grouse commences a half-hour before sunrise.

Ruffed grouse populations peak every 10 years, then fall dramatically before beginning a steady upturn. The last ruffed grouse population peak happened in 2009. Biologists don't understand the reason grouse populations cycle up and down despite years of extensive research.

The Minnesota Department of Natural Resources each spring conducts ruffed grouse drumming counts. The good news is this spring the statewide counts were up 57 percent. Males produce a drumming sound as they flap their wings as part of their display to attract females. Drumming counts are a marker of the breeding population.

The 2017 drumming surveys appear to verify the 10-year population upturn is nearing its peak.

Will the positive drumming counts result in more grouse flushes for hunters? We'll see. I have not seen a brood of grouse all summer in central Minnesota. Neither have most of my friends. However, in northeast Minnesota, anecdotal information suggests grouse numbers are high, with many sightings of a number of hens with chicks. One person told me, "Grouse are everywhere."

Still, a wet June in central Minnesota may have been tough on young grouse. The tiny balls of fluff are vulnerable to cold, rainy weather during their first week of life, and can easily succumb to hypothermia.

Those willing to stomp the forests Saturday should flush at least a few birds. Despite a grouse population that fluctuates, Minnesota is the nation's top producer of ruffed grouse, even during low population cycles.

Throughout most of the forested regions of Minnesota, the favorite fall food of ruffed grouse is the fruit of gray dogwood. This head-high shrub produces small, white or light green berries that ruffs find irresistible. Gray dogwood grows in damp areas and is prevalent in the transition zone where alder lowlands rise and meet an aspen forest. Also look for gray dogwood along creeks, especially those with an open canopy. Ruffed grouse may be found feeding on dogwood fruit throughout the day, but the best time to hunt around food sources is during late afternoon because grouse will fill before going to roost.

Opening day grouse hunters can also find birds along logging trails, or the edges of meadows and other forest openings. Ruffed grouse like to feed on sun-loving plants. Openings in the forest allow certain plant species to prosper that would otherwise be unable to compete.

Dogwood, chokecherry, hazel, high-bush cranberry, clover, wild strawberry and other grouse favorites grow along logging roads or on the edges of openings.

Here are a few more tips for the early grouse hunter:

• If you flush a grouse and don't get a shot (or miss) it is usually a good idea to walk in the direction the grouse flew. Birds early in the season typically don't fly more than about 150 yards before landing.

• A good dog is invaluable to finding grouse, especially during early season before the leaves have fallen.

• The daily limit on ruffed grouse is five, with 10 in possession.
