The Minnesota Department of Natural Resources’ latest ruffed grouse counts found Minnesota’s spring 2026 population declined from its peak in 2024. Ruffed grouse drums per stop were 1.7 statewide, which is down slightly from last year. Drumming is a low sound produced by males as they beat their wings rapidly and in increased frequency to signal the location of their territory. Drumming displays also attract females ready to begin breeding.
The DNR and its partners have conducted ruffed grouse surveys for 75 years to monitor the state’s breeding population. Through decades of surveys, DNR researchers have found that ruffed grouse populations tend to rise and fall in a cycle that typically ranges from 8-11 years.
“Drumming counts alone are not an accurate way to predict the birds that will be present during the fall hunting season,” said Charlotte Roy, DNR grouse project leader. “Nesting success and chick survival during the spring and summer are contributing factors that influence the number of birds present in the fall. These factors can be reduced by heavy rain during June, when nests hatch and chicks are young.”
The ruffed grouse populations were surveyed by counting the number of male ruffed grouse drums on established routes throughout the state’s forested regions.
“In a typical year, we have 13 cooperating organizations helping us count grouse drumming,” Roy said. “We are grateful to our federal, Tribal and other partners for their assistance in completing routes.”
