Minnesota’s ruffed grouse spring drumming counts were significantly higher than last year across most of the bird’s range, according to a survey conducted by the Minnesota Department of Natural Resources.
“Ruffed grouse drums increased 34 percent from the previous year, with the increase happening in the northern part of the state,” said Charlotte Roy, DNR grouse project leader. “This may signal the start of an upswing in the grouse cycle that since 2009 has been in the declining phase.”
The increase is consistent with changes typical of the 10-year grouse cycle. The most recent peak in drum counts occurred in 2009. The cycle is less pronounced in the more southern regions of the state, near the edge of the ruffed grouse range.
