ST. PAUL — A long winter followed by a cold, wet spring contributed to a significant decrease in Minnesota’s pheasant count, which declined 29 percent from 2012, according to Minnesota DNR officials.

“Minnesota’s results reflect what we’re seeing in other states,” said Rachel Curtis, DNR wildlife research biologist. “South Dakota had a 64 percent decrease in its brood survey. North Dakota’s most-recent rooster crowing count is down 11 percent from last year. And Iowa reported a 19 percent decrease in its August roadside count.”

Minnesota’s 2013 pheasant index is 64 percent below the 10-year average and 72 percent below the long-term average.

Pheasant hunters still are expected to harvest about 246,000 roosters this fall. That’s down 44,000 from last year’s estimate and is less than half the number of pheasants taken during the 2005-2008 seasons when hunting was exceptionally good.

The highest pheasant counts were in the southwest region, where observers reported 51 birds per 100 miles of survey driven. Hunters should find good harvest opportunities in west-central, east-central and south-central Minnesota.

“Pheasant populations respond to habitat abundance and changes in weather,” Curtis said. “The steady downward trend in Minnesota’s pheasant population during the past several years is primarily due to habitat loss. Weather has caused minor fluctuations.”

High spring precipitation and below average temperatures hurt nesting this year. This year’s average hatch date was delayed to June 20, which is 11 days later than the 10-year average of June 9.

Although fewer broods were seen, brood size was larger than last year and comparable to the long-term average. Actual reproduction rates may be higher than the survey suggests. Hens that were successful nesting later in the season tend to be underrepresented in roadside data and it is possible that hens were still nesting or in heavier cover with young chicks during the survey period.

The pheasant population estimate is part of the DNR’s annual August roadside wildlife survey, which began in 1955. DNR conservation officers and wildlife managers in the farmland region of Minnesota conduct the survey during the first half of August. This year’s survey consisted of 171 routes, each 25 miles long, with 152 routes located in the ring-necked pheasant range.

Observers drive each route in early morning and record the number and species of wildlife they see. The data provide an index of relative abundance and are used to monitor annual changes and long-term population trends of pheasants, gray (Hungarian) partridge, cottontail rabbits, white-tailed jackrabbits, mourning doves and other wildlife.

The gray partridge index also decreased from last year and remained below the 10-year average. The cottontail rabbit index increased from last year but stayed below the 10-year and long-term average. The jackrabbit index was 87 percent below the long-term average. Finally, the mourning dove index was 20 percent below last year and lower than the 10-year and long-term averages.
