The greater prairie chicken is a rare bird species native to the grasslands of North America. It was once abundant, with millions of birds in Illinois alone in the 1800s, but its population has declined significantly due to hunting, egg collecting, habitat destruction, and other factors. Today, the greater prairie chicken is considered threatened or vulnerable, with small populations scattered across the Great Plains from Canada to the Mexican Gulf Coast. Conservation efforts are underway to protect and restore their habitat and prevent their extinction. While the exact number of greater prairie chickens is unknown, it is estimated that their population has dropped to approximately 500,000 individuals across North America.

What You'll Learn
The greater prairie chicken population in the 1800s
The greater prairie chicken, now a rare bird, was once abundant across the prairies of North America. In the 1800s, these birds numbered in the millions in Illinois alone, with approximately 10 million recorded in 1860. A steamboat captain in 1840 recalled seeing "millions" of prairie chickens at Bird's Point. They were widespread across the oak savanna and tall grass prairie ecosystem.
The greater prairie chicken is a non-migratory bird, spending its entire life within the few remaining tallgrass prairie habitats. They are strong flyers and may travel up to 30 miles in search of wintering grounds. They are distinguished by their brown and white-barred feathers, with males having orange neck sacs and long black neck feathers.
The population of the greater prairie chicken has declined dramatically over the past century, primarily due to hunting and habitat loss. In Illinois, by the early 1990s, their numbers had dwindled to around 40 birds, and they were nearly extirpated from the state. Hunting and egg-collecting, as well as habitat destruction, were the main causes of their decline. The species is also threatened by loss of genetic diversity due to the isolation of small populations.
Today, the greater prairie chicken is considered endangered in Illinois and vulnerable on the IUCN Red List of Threatened Species. While they were once common in states like Iowa, Missouri, Indiana, and Kentucky, they have now disappeared from these areas. The current population across North America is estimated to be around 500,000 individuals, with small populations scattered throughout the Great Plains and into Canada.

Current population estimates
The greater prairie chicken was almost driven to extinction in the 1930s due to hunting and habitat loss. In Illinois, their numbers dropped from millions in the 1800s to just around 200 in 2019. The species is now considered vulnerable on the IUCN Red List of Threatened Species and is threatened in several states. While it is not federally listed as endangered, it is considered threatened across its range.
The greater prairie chicken population has declined severely across North America, with estimates placing their numbers at approximately 500,000 individuals. In Iowa and Missouri, which once had thriving populations estimated to be in the hundreds of thousands, numbers have dropped to about 500. Central Wisconsin is home to approximately 600 individuals, a significant decrease from the 55,000 recorded when hunting was prohibited in 1954. Kansas, Nebraska, and South Dakota are currently home to the largest remaining populations.
In Illinois, wildlife management has included the "genetic rescue" of small and potentially inbred populations by introducing birds from other areas. The Missouri Department of Conservation has also initiated a program to import prairie chickens from Kansas and Nebraska, aiming to increase their population to 3,000. Over 30,000 acres of land in Wisconsin are managed by the Wisconsin Department of Natural Resources as greater prairie chicken habitat.
The greater prairie chicken prefers undisturbed prairie and was originally found in tallgrass prairies. They can tolerate agricultural land interspersed with prairie, but populations are sparser in areas with higher levels of agriculture. Their preferred habitat is now threatened by wind energy development, which requires large, open expanses of grass without trees or other tall objects that could serve as perches for potential predators.

Population distribution
The greater prairie chicken was once widespread across the oak savanna and tall grass prairie ecosystem. However, their population has declined severely over the past century, primarily due to habitat loss as native prairies were converted into agricultural farmland. Hunting, egg collecting, and the introduction of ring-necked pheasants have also contributed to their near-extinction in the 1930s. While the current population across North America is estimated to be around 500,000 individuals, this represents a significant decrease from historical numbers.
In Illinois, for example, there were approximately 10 million prairie chickens in 1860, but by the early 1990s, their numbers had dwindled to around 40 birds. While the population recovered to about 200 individuals by 2019, the species remains endangered in the state. Similarly, in Iowa and Missouri, which once had thriving populations estimated in the hundreds of thousands, the total numbers have dropped to approximately 500 birds in recent years. Central Wisconsin has also witnessed a drastic decline, with only 600 individuals remaining, compared to 55,000 when hunting was prohibited in 1954.
Despite these concerning trends, there are some success stories. In Colorado, the greater prairie chicken was once listed as endangered, with population levels dipping to as low as 600 birds in 1973. However, through recovery efforts, including cooperative habitat projects with landowners, their numbers have increased, and they are now flourishing in the grasslands of the state's northeast corner.
The greater prairie chicken prefers undisturbed prairie habitats and can be found in small populations throughout the Great Plains, ranging from Canada to the Mexican Gulf Coast. The largest remaining populations are in Kansas, Nebraska, and South Dakota. While they can tolerate agricultural land mixed with prairie, sparser population densities are observed in more agricultural areas.

Threats to population
The greater prairie chicken was almost driven to extinction in the 1930s due to a combination of hunting pressure, egg collecting, and habitat loss. While it is not federally listed under the Endangered Species Act, it is considered threatened in several states and vulnerable on the IUCN Red List of Threatened Species. The species is still at risk, with the primary threat to remaining populations being further habitat loss.
Greater prairie chickens prefer undisturbed prairie and were originally found in tallgrass prairies. They can tolerate agricultural land mixed with prairie, but only to a point—sparser population densities are found in areas that are more agricultural. Wind energy development is a new and significant cause of habitat loss, as prairie chickens require large, open expanses of grass without trees or other tall objects that could provide a perch for a predator. If they can see a structure, such as a wind turbine, they won't stay in an area.
The species is also threatened by the loss of genetic variance resulting from the isolation of populations with no natural corridors between groups. In Illinois, wildlife management has included the "genetic rescue" of small and potentially inbred populations by introducing birds from other areas.
In addition, greater prairie chickens face threats from pesticides and collisions with manmade structures.

Population management
The greater prairie chicken was once abundant across the tallgrass prairies of North America, but its population has declined severely over the past century, primarily due to hunting and habitat loss. In Illinois, their numbers dropped from millions in the 1800s to near extinction in the 1930s. Today, they are considered "Threatened" in several states and "Vulnerable" on the IUCN Red List of Threatened Species.
Habitat Improvement: Most management efforts focus on habitat improvement, as the loss of native prairie to agriculture and development is the single greatest threat to the greater prairie chicken. Organisations like The Nature Conservancy are working to restore tallgrass prairies and manage land specifically for the species' habitat requirements. This includes preserving and restoring large tracts of native grassland, which is vital for the greater prairie chicken's survival, as they require expansive, undisturbed areas of grass without trees or other structures that could provide perches for predators.
Genetic Diversity Preservation: Greater prairie chickens also face the threat of genetic variance loss due to isolated populations with no natural corridors between them. To address this, wildlife managers have implemented "genetic rescue" programs, where birds from other areas are introduced to small, inbred populations to increase genetic diversity and improve offspring survival. This has been done in Illinois, where greater prairie chickens were trapped in Midwestern states with healthier populations and released into sanctuaries.
Population Reintroduction: Population reintroduction may be necessary to bolster severely depleted populations and prevent local extinctions. For example, the Missouri Department of Conservation has initiated a program to import prairie chickens from Kansas and Nebraska, aiming to increase their numbers in the state.
Sustainable Land Management: Working with ranchers and landowners to implement sustainable grazing practices on grasslands can benefit both grassland birds and other species, such as monarch butterflies. Additionally, addressing threats like pesticides and collisions with manmade structures can further support greater prairie chicken populations.
Predator and Competition Management: Introduced species, such as the ring-necked pheasant, can negatively impact greater prairie chicken populations. Managing these invasive species and their predators can help reduce competition and predation risks for the greater prairie chicken.
