The Reintroduction of
Prairie Chickens to Iowa

The group of bird watchers
shivered in the chill of dawn in early April. Braving the chill air
was worth it, however. On a ridge top, a few hundred yards east of
the observation deck were 14 male prairie chickens competing for the affections
of four hens who were also visiting this booming ground. Booming
grounds are communal display areas where male prairie chickens are found
each spring during March, April, and May. The vocalizations that
male prairie chickens make while displaying is called booming. These
sounds the male birds make by releasing air from special brightly colored
air sacks on their necks. For nearly 50 years, the booming of male
prairie chickens has been absent in Iowa. Today, however, the sounds
of prairie chickens once again reverberate across their original Iowa range
thanks to many generous individuals and work of the Iowa Department of
Natural Resources Wildlife Bureau.
At the time of European
settlement in the mid-nineteenth century and until about 1900, prairie
chickens commonly nested throughout the state of Iowa. Their
preferred habitat is an open, treeless expanse of grassland, something
found across the state at that time, but now quite scarce in Iowa.
During
the late nineteenth century, prairie chickens were the most abundant gamebird
on the Iowa prairies and hunting and trapping them was very important to
settlers, both for food and market. As agricultural land use intensified,
populations of prairie chickens started to decline. By the
1950’s the only known nesting prairie chickens were in Appanoose, Wayne,
and Ringgold Counties in southern Iowa . The last verified nesting
prior to later reintroduction attempts was in Appanoose County in 1952
.
In the early 1980’s the
Iowa Conservation Commission, now the Iowa Department of Natural Resources
(DNR), made an unsuccessful attempt to restore prairie chickens in the
loess hills of western Iowa. A second reintroduction program was
initiated by the IA DNR in 1987. This time the release site was on
the Ringgold Wildlife Area located two miles north of the Missouri border
in Ringgold County in south central Iowa. The DNR considered the
region around this site to be the best potential prairie chicken habitat
in Iowa. Recent years had brought some positive changes in the grasslands
of the Area, and it was hoped that these changes would provide suitable
habitat for prairie chickens once again. A major change was restoration,
through management, of around 500 acres of prairie on the Ringgold Wildlife
Area. Other changes were better pasture management by some area farmers,
and the Conservation Reserve Program of the United States Department of
Agriculture which converted thousands of acres of cropland into a
diversity of mostly undisturbed grasslands for at least 10 years.
The
birds for this reintroduction were obtained from Kansas. Crews from
Iowa trapped the prairie chickens on booming grounds in the spring and
immediately hauled the birds to Iowa where they were released. A
total of 254 prairie chickens were moved to the Ringgold Wildlife Area
from Kansas during the years 1987, 1988, and 1989. Another 295 birds
were captured in Kansas and stocked in Ringgold and Adair Counties in 1991,
1992, and 1993.
The program has proven
successful. This spring there are several prairie chicken booming
grounds in Ringgold and Decatur Counties as well as in nearby areas
of Missouri and there have been numerous sightings in Wayne County.
To insure that at least
minimal habitat for prairie chickens and other grassland birds exists in
the future, the DNR and Partners in Flight initiated the Kellerton Bird
Conservation Area. The goal of this project is to have a core area
of 2000 acres of publicly owned and managed grasslands within a 10,000
acre block that contains at least another 2000 acres of privately held
grassland habitat. To date the DNR has acquired 680 acres with the
financial support provided by REAP grants and monies donated by various
conservation groups and individuals. The Kellerton Bird Conservation
Area is being actively managed to provide optimal habitat for the area's
prairie chickens though activities such as tree removal, prairie restoration,
burning, and grazing.
The
Kellerton Bird Conservation area is home to the largest known booming ground
in Iowa, and the DNR and WOODLINK, LTD, a manufacturer of quality birdhouses
and birdfeeders, have constructed a raised viewing platform from which
Iowans can observe the annual spring displays of prairie chickens .
Viewing is best within an hour of sunrise or sunset during the months of
March and April, with some activity on the booming ground until the end
of May. On nice mornings, males can also be seen on the site from
mid October through February. The viewing platform is open to visitors
at all times, and is handicapped accessible. Visitors are asked to
respect the no trespassing signs which have been posted to avoid disturbance
of the booming ground from February through mid-May.
If your computer is equipped
with a sound card and speakers you can hear a 15 second recording of the
chickens booming by clicking the link below. The sound is more like
a "whoo, whoo, whoo, chatter, chatter, whoo, whoo, whoo..." The day
of the recording the wind was blowing which affected the recording quality.
For a better quality sound experience you'll just have to visit the prairie
chickens yourself.
