| History
Originally an Asian species, the ring-necked pheasant
was successfully introduced into North America in 1881 and into Iowa about
1900. Iowa’s first ring-necks were introduced accidentally when a
severe windstorm wrecked the pens of game breeder William Benton of Cedar
Falls releasing approximately 2,000 birds. Benton’s birds spread
north and west and constitute Iowa’s founding stock. The DNR began
stocking pheasants around 1910 with most regions of Iowa receiving large
stockings of ring-necks by 1930. The ring-neck has since become the
most important gamebird in Iowa with an estimated statewide population
of 4 to 6 million birds. Pheasants are found on rich farmlands throughout
the state, but they are most numerous on land that has a good mixture of
agriculture, hay, idle grassland, and wetlands. Early on, 1930-40’s,
northwest and northcentral Iowa boosted Iowa’s best pheasant numbers, but
as row crop agriculture intensified, eliminating wetlands and haylands,
Iowa’s best pheasant range has shifted to southern Iowa in the 1970’s.
However, the idling of farmland under the Conservation Reserve Program
in 1985 has shifted pheasant numbers back to northern and eastern Iowa.
The DNR uses an August Roadside Survey to monitor pheasant populations.
The survey is conducted in early August with over 6,000 miles of
gravel roads driven annually to estimate population trends. Iowa’s
abundant interspersion of grasslands and croplands make her one of the
top pheasant harvest states in the nation with an average annual harvest
of 1.2 to 1.4 million roosters. Many local retailers and chamber
of commerce refer to Iowa as the pheasant capitol of the world.
Identification
Pheasants are long-tailed, seed-eating, chicken-like
gamebirds. Male pheasants, “roosters or cocks” are brilliantly colored
with a combination of russet, copper, brown, gray and black on the body,
iridescent dark green on the neck, and bright red wattles on the head.
A white neck ring is present on most males. In contrast, females
or “hens” are light brown with black flecking on each feather. Newly
hatched chicks are covered with soft buff-colored down with dark markings
on the head and back, and weigh about a half an ounce. Juveniles
of both sexes, up to 10 weeks old, resemble females in color, and by 16
weeks of age, they are almost indistinguishable from adults. Adult males
weigh about 2 ¾ pounds and females about 2 pounds. Cock pheasants
have spurs on their legs that increase in length, as they grow older
The spurs on juvenile males are generally less than 3/8 of an inch in length;
spurs on old males may be almost an inch long. |
| Reproduction
Increasing day length triggers reproductive activity
among pheasants. Cock pheasants begin crowing, fighting, and establishing
breeding territories to attract hens in early March. Pheasants are
polygamous, meaning one male will breed many hens. Pheasants do not
form pair bonds. Pen studies indicate hens can continue to lay fertile
eggs for three weeks after a single mating, and one cock is capable of
mating with 50 hens with no loss of fertility. Nesting can begin
as early as March in southern Iowa, but egg laying usually begins in mid
to late April, peak incubation occurs in May, and peak hatch is usually
early to mid June. Only the hen takes part in nesting and incubation. |

 |
Hens conceal their nests in
dense, erect grassy vegetation at least 8 to 10 inches tall. The
nest bowl consists of a shallow, scratched-out depression in the ground
that is lined with grass or leaves. Hens lay about an egg a day and
first nests usually have 10 to 12 eggs. The eggs hatch in about 23
days. A complete nesting cycle from laying to hatch takes about 37
days. The young chicks hatch covered in down (precoccial) and can
leave the nest and follow the hen within a few hours of hatching.
Young can make short flights at 12-14 days of age and resemble adults by
16 weeks of age. Pheasant hens are persistent renesters, meaning
they will initiate new nests if their existing nest is destroyed.
This is why many people report seeing different age broods during the summer.
This is also why many people think pheasants produce more that one brood
per year. However, research has shown that hen’s only hatch one nest
per year; older broods are from first nests and younger broods are
from renests. Because of the hen’s persistence and large clutch size,
pheasant populations in Iowa can double or triple in a single season given
proper weather and spring habitat. |
| Food Habits
Because of their rapid growth rate, the diet of young
chicks is comprised almost entirely of protein from insects, spiders, slugs
and other invertebrates until six weeks of age. Seeds and other plant
materials become more important in the diet of, older birds. Corn
and soybeans are very important fall, winter and spring foods. Weed
seeds, berries and green vegetation also are consumed, but pheasants are
seldom found in areas where they do not have easy access to agricultural
crops. Pheasants can meet their daily water requirements through
daily feeding activities, thus water is not required.
Limiting Factors
Lack of adequate nesting and winter habitats are the
biggest limiting pheasant numbers in Iowa. Changes in land use and intensive
row-crop farming have reduced the availability of suitable nesting and
winter habitat in Iowa since 1940. A comparison of 1939 and 1972
aerial photographs from 27 counties in north-central Iowa (Iowa's traditional
pheasant range) revealed a 76 percent decline in good quality pheasant
nesting cover and a 33 percent decline in winter cover. A shortage
of suitable nesting and brood-rearing habitat has resulted from the elimination
of many pastures, idle areas, hay and small grain fields. Increased
herbicide use with cleaner and larger crop fields have also contributed
to the loss of pheasant habitat. Research in Iowa has shown that
narrow, linear strips and small patches of nesting habitat , less than
40 acres, are death traps for nesting hens because predators can search
these small habitats very effectively. Pheasant populations have
improved in areas where blocks of cropland have been enrolled in the Conservation
Reserve Program. The Conservation Reserve Program provides larger
blocks of idle grasslands for nesting and wintering pheasants. In
spite of this program, however, much of Iowa still lacks adequate pheasant
habitat.
Waste grain is a widely available and readily accepted
food source, and lack of food rarely becomes a limiting factor to Iowa
ring-necks. However, fall plowing and deep snow can certainly reduce available
food supplies. Fall plowing has been reported to reduce the amount of available
waste grain in a picked cornfield from more than 200 pounds per acre to
about 15 pounds per acre. Predation, hunting, severe weather, accidents
and other factors obviously contribute to pheasant mortality, but given
suitable habitat, pheasant production can equal or exceed annual losses.
Habitat Needs
Hayfields, oat fields, pastures, idle grassland areas,
wetlands and Conservation Reserve Program lands provide good pheasant nesting
cover. Hens seek out herbaceous, grassy areas (fields with a mixture of
grasses and forbs) for nesting because diverse fields provide abundant
insects for newly hatch chicks and the forbs reduce the density of the
grasses making it easier for the chicks to move around. Mowing hayfields
and grassy areas in June and July results in severe nest losses, and chick
and hen mortality. Delaying hay mowing until the pheasant-nesting season
is over is impractical for the farmer. However, the use of native
prairie grasses for hay and pasture greatly reduces nest disturbance in
June. Researchers have found pheasants prefer tall, herbaceous grassy
habitats for nighttime roosting cover, while areas with tall weeds or shrubby/brushy
habitats and a minimum of ground cover are usually selected for loafing.
Dense ground cover may help roosting birds retain body heat at night while
open brushy areas provide safety from predators while allowing the birds
an opportunity to sun themselves on clear winter days. Tall, lush stands
of cattail, bulrush or switchgrass about 20 to 40 acres in size are good
examples of winter roost habitat.
During blizzard conditions, tall, dense vegetation
that effectively stops snow drift and greatly reduces wind-chill is essential
to pheasant survival. Large, multi-row conifer windbreaks with dense, low-hanging
branches, and tall, dense cattail or bulrush marshes provide safe refuges
for pheasants during blizzards. Unfortunately, farmers often remove these
cover types to make way for larger cropfields. Research indicates four
good wintering areas (each 20 acres or larger in size) per township are
sufficient to support a good pheasant population. Smaller wintering areas
tend to drift full of snow and become death traps for pheasants during
severe blizzards. Food plots should be situated adjacent to winter habitat
as pheasants seldom travel more than ¼ mile from winter habitat
to feed.
Pheasant stocking, predator control, winter-feeding
and reduced hunting pressure do not automatically result in greater pheasant
populations. Severe weather can result in dramatic, short-term fluctuations
in pheasant populations, but long-term trends in pheasant numbers reflect
the quality and quantity of the habitat. |
| Hunting
Pheasant hunting in Iowa begins the last Saturday in
October and runs through 10 January. Harvest is limited to cocks only.
The majority of the hunting activity for Iowa's 140,000 resident and 40,000
non-resident pheasant hunters occurs on Iowa's 34 million acres of private
land during the first three weeks of the season. It is absolutely essential
for everyone to respect private property and obtain permission from the
landowner prior to hunting.
If you are unable to locate a hunting spot on private
lands, the Iowa Department of Natural Resources maintains 300 public hunting
areas, which total 300,000 acres. Public hunting areas often provide very
good hunting late in the season after cold weather has concentrated the
birds in heavy cover.
Equipment needed for successful pheasant hunting is
minimal compared to other shooting sports. Warm clothing, good walking
boots and a shotgun are about all you really need. There is a lot of personal
preference involved with selecting a pheasant gun. Many hunters use 12-gauge,
full-choke shotguns and number #4 or #5 shot. Such hardware may be essential
for long shots late in the season, but other hunters prefer an open-bore,
20-gauge with #6 to #7-1/2 loads for early-season roosters.
A wide variety of techniques can be used when hunting
pheasants. This is probably one of the reason pheasant hunting appeals
to so many people. A lone hunter can usually hunt field edges, fencerows
and small weed patches. Many enjoy the solitude and easy pace of this type
of hunting. Larger blocks of cover such as standing cornfields, cattail
marshes, shelterbelts and large waterways may be difficult for one hunter
to cover. Several hunters working together not only find more birds, but
sharing the outdoor experience with good friends can be a very important
part of the hunt. Larger hunting parties have found that they can bag more
birds if they post "blockers" at the far end of the field, particularly
if the birds seem prone to running or flushing wild. For many hunters,
it just isn't a pheasant hunt unless you have a good bird dog along. A
well-trained dog is a tremendous help in locating and retrieving crafty
ring-necks. Selecting a good bird dog is again a matter of personal preference.
English setters, Brittany spaniels, German shorthair/wirehair pointers
and Labrador retrievers seem to be some of the most popular breeds among
Iowa pheasant hunters.
Once the bird has been bagged, it is essential to take
good care of the meat, particularly if the weather is warm. Perhaps the
best way is to dress and cool the meat immediately after the hunt. Almost
any recipe calling for chicken will also work on pheasants.
During some years, Iowa hunters harvest as much as
80 percent of all the available roosters. In biological terms this is not
excessive. Due to their polygamous breeding habits, only a small percentage
of the males are actually needed for reproduction the following spring.
Iowa's comparatively long; cock-only season is really quite conservative
because the hen segment of the population is always protected from legal
hunting losses. Shortening or closing a cocks-only pheasant season during
population lows does not result in increased pheasant production in the
future, because hens are protected and the lack of breeding males has never
been a limiting factor for Iowa pheasants.
Economics
Pheasant hunters outnumber all other Iowa hunters.
Revenue from licenses, wildlife habitat stamps and excise taxes on sporting
arms and ammunition provides money needed for many Iowa DNR programs, including
land acquisition, habitat development, wildlife management and wildlife
research. These activities ultimately result in better habitat conditions
for a wide variety of upland wildlife species.
Iowa pheasant hunting is also important to the economy.
Owners of restaurants, service stations, discount centers, motels, and
grocery, hardware, dry goods and sporting goods stores all benefit from
money spent by the Iowa pheasant hunter. Many hotels/motels in Iowa have
no vacancies during the first few weekends of Iowa’s pheasant season.
According to the most recent survey, Iowa residents and non- residents
spend $85 million annually, exclusive of license fees, to hunt pheasants
in Iowa. Through multiplier effects, spending by retailers and wholesalers
as result of the hunter’s original purchase, pheasant hunting generates
an additional $154 million of additional spending annually. Taken
together pheasant hunting’s impact on the Iowa economy approaches almost
a quarter billion dollars annually. |
