Upland Game Birds Minnesota’s upland game birds include
ruffed, spruce, and sharp-tailed grouse, ring-necked pheasant, turkey, woodcock, and the gray partridge.
3
The ruffed grouse – mixed forests
4
The sharp tailed grouse and the prairie chicken in the open grasslands in summer and brush/woodlots in winter

Spruce Grouse - northern conifer forests

bobwhite quail – southeastern MN

Bobwhite quail are no longer hunted in MN

Upland Game Birds
The gray partridge (Hungarian partridge or Huns) and the Pheasant were both introduced.

– The wild turkey has been reintroduced

Woodcock – Alder forests

Upland Game Birds
Ruffed Grouse– The ruffed grouse gets its name from the
ruffs on the sides of its neck.– Ruffs are present on both sexes but are
larger in the male than the female.– Ruffed grouse are mistakenly called
“ruffled grouse”
13
Upland Game Birds
– Of 1000 chicks hatched in a year• 45% survive one year• 19% survive two years• 8% survive three years• 4% survive four years• 1% will survive five years
– Up to 55% of the fall population die during 1st winter
– Hunters take a portion of this 55%.
14
Upland Game Birds
Characteristics– The ruffed grouse is about half the size of
a pheasant.– Weighing between 1 and 1 1/2 pounds.– The grouse is noted for its fan shaped tail
marked by a broad, dark band.
15
Upland Game Birds– Camouflage is its best protection against
predators– Uses patterns and mixtures of browns, blacks,
whites, and grays
16
Upland Game Birds
– During winter grouse rely on snow roosts to survive from the cold.
17
Upland Game Birds
– Grouse dive or burrow into deep fluffy snow
– Temps can be 20-30 degrees warmer than the air temperature
– Also protected from the wind– Winters with little/no snow are hard on
grouse survival rates

Upland Game Birds
– Grouse wings are short and wide, and cup shaped
– Allows them to be a very fast flier, but only for short distances.
– Grouses bill is adapted for eating buds, twigs, berries, seeds, and leaves.

Upland Game Birds
Color Phases– Many species of wildlife have various color
phases.– Red fox can be red, black, or crossed.– black bear can be black or brown.– Grouse also have color phases – There is a red phase, a gray phase, and a
mixture phase.
21
Upland Game Birds
– An individuals bird’s color phase is partly controlled by genetics
– Gray more common in northern part of the range.
– Red in southern end

Determining Male/Female The sex of a ruffed grouse can be
determined by looking at the tail feathers.– Check the band on the two middle tail
feathers– Complete band = male– Incomplete band = female

Male or Female?

– Another method is to pluck feathers from the lower back of the grouse. Count the number of white dots.
– Females one dot while – Males have two or more.

Upland Game Birds
Determining Age– Ruffed grouse are separated into three age
classes.• Chicks, juveniles, and adults
– Chicks hatch in May or June and are noticeably smaller that the adults until they are about 10 or 12 weeks old.
– Ruffed grouse are capable of breeding at one year of age; then considered adults.
31
Upland Game Birds
– Outermost flight feathers are a key to determining age.
– Grouse have 10 major flight feathers, called primaries, on each wing.
32
Upland Game Birds
Habitat– Aspen-birch hardwood forest is typical
grouse habitat in MN, – Alder and patches of gray dogwood are
used by grouse in summer and fall.
33
Upland Game Birds Management
– Aspen buds are primarily winter food for grouse and young aspen are important cover for broods
– To benefit grouse it is important to maintain aspen forest of three ages
• Stands of suckers less than 10 years old for brood cover
• Trees 10-25 years old for wintering and breeding cover.
• Older aspen for food, wintering, and nesting cover.
34
Upland Game Birds
– IDEAL HABITAT can produce 1 bird every 1.25 acres
– Average habitat will have 1 every 4 acres– Poor habitat will have 1 every10 acres

36
Upland Game Birds History
– Ruffed grouse are solitary.– A male grouse normally occupies a territory by
October of his first fall.– Territory area covers about 60 acres.– Usually each hen will range over territories of
two or three males
37
Upland Game Birds
– Drumming can be heard at all times of the year
– In mid April, drumming becomes more active.
– Males advertise their location to interest hens, and their territory to other males.
– Drumming reaches a peak about the last week in April

Upland Game Birds
Brood– After mating, hens disperse to find a
nesting site, which may be ½ mile from where they mated
– Nests are in an open forest near mature male aspen
– Hen will lay 10 – 14 eggs at a rate of about 2 every 3 days
40
Upland Game Birds– The eggs hatch after about 23 days of
incubation.– Males play no role in nesting or caring for the
brood.– For the first couple of weeks the chicks feed
almost entirely on insects and then eat plant material
41
Upland Game Birds
– It takes 16 weeks to become fully grown.– Toward the end of Sept broods break up
and the young scatter– Early season hunters may find broods
together before dispersal, or fall shuffle.
42
Upland Game Birds
– Winter food consists primarily of the male catkins or flower buds of several species, aspen being most important.
– Sharp Shinned, Cooper’s Hawk and great horned owls are probably their biggest predators.
43
Upland Game Birds
– Whether hunted or not hunted the grouse population usually drops about 55% though winter.
– About every 10 years they become very abundant and then decline sharply over a period of two or three years
– Over the past ½ century peak populations have usually occurred in years ending in 1, 2, 3 and the bottom of the cycle in years ending in 5, 6, 7.
44
Upland Game Birds
– Reasons for grouse in population cycles have not been determined.
– In good habitat, fluctuation is less – Hunting does not seem to affect grouse
population cycles.
