Mixed results for ruffed grouse, pheasant and waterfowl
The Wisconsin Department of Natural Resources (DNR) announced the annual spring surveys of Wisconsin ruffed grouse and pheasant showed below-average counts. By contrast, the results of the spring waterfowl breeding survey indicate good numbers and excellent habitat conditions for migratory birds.
DNR wildlife biologists reported a 5 percent decrease statewide in ruffed grouse drumming activity from 2021.
“These results are not surprising. Ruffed grouse typically follow a 10-year population cycle,” said Brian Dhuey, DNR wildlife surveys specialist. “While we don’t have data for 2020 due to COVID-19 restrictions, we know that cycles usually peak in years ending in 9, 0 or 1. We’re likely going to see that abundance begin to wane in the coming years as we enter the ‘down phase’ of the cycle.”
The department also reported a slight increase in pheasant observations compared to 2021 in its annual spring ring-necked pheasant survey. However, the count remained below the most recent five-year average. DNR wildlife managers use a measurement known as an abundance index to assess the state’s wild pheasant population each year. This assessment is a roadside count of crowing males that accounts for the number of breeding males in the area and indicates the abundance of pheasants going into the breeding and nesting season. The abundance index was the highest in the northwestern part of the state, but all three areas had an increase in their abundance index in 2022.
The DNR’s annual breeding waterfowl survey also took place this spring. The survey showed stable to increasing numbers for two of the state’s primary breeding waterfowl: mallards and blue-winged teal. The third primary species, wood ducks, showed a slight decline. The survey team also reported above-average wetland conditions.
Canada goose numbers are up as well compared to 2021, consistent with the stable to increasing population seen over the past 10-15 years.
