Why did the prairie chicken go extinct?
Greater Prairie-Chicken populations declined to near-extinction over the past century, mainly due to habitat loss as native prairie was converted to farmland. Loss of genetic diversity, pesticides, and collisions with manmade structures also pose threats. Which Prairie-Chicken?
Are prairie chickens endangered in Texas?
Attwater's prairie chickens are found only on the coastal prairies of Texas. Prairie chickens are endangered because the tallgrass prairie has been plowed for farmland and covered by cities. Habitat has also been lost because of heavy grazing by cattle, although some cattle ranches maintain good grassland habitat suitable for prairie chickens.
Why is the greater prairie chicken population decreasing?
Due to their now small populations and habitat fragmentation the greater prairie chickens often undergo inbreeding causing observable inbreeding depression: with fewer offspring and a decreased survival rate within these limited offspring further aiding their population decrease.

How many greater prairie chickens are left?
They now only live on small parcels of managed prairie land. Throughout North America, it is thought that their current population has declined severely, to approximately 500,000 individuals.
What is the main threat to the greater prairie chicken today?
Aside from habitat loss, the greater prairie chicken is also threatened by loss of genetic variance resulting from the isolation of populations with no natural corridors between groups. Most management focuses on habitat improvement, but population reintroduction may eventually be necessary to ensure genetic diversity.

What is a boomer chicken?
The greater prairie chicken or pinnated grouse ( Tympanuchus cupido ), sometimes called a boomer, is a large bird in the grouse family.
How long does it take for a prairie chicken to hatch?
Hens lay between 5 and 17 eggs per clutch and the eggs take between 23 and 24 days to hatch. There are between five and 10 young per brood. (INRIN, 2005). The young are raised by the female and fledge in one to four weeks, are completely independent by the tenth to twelfth week, and reach sexual maturity by age one (Ammann, 1957). A study of female greater prairie chickens in Kansas found that their survival rates were 1.6 to 2.0 times higher during the non-breeding season compared to the breeding season; this was due to heavy predation during nesting and brood-rearing. One problem facing prairie chickens is competition with the ring-necked pheasants. Pheasants lay their eggs in prairie-chicken nests. The pheasant eggs hatch first; this causes the prairie chickens to leave the nest thinking that the young have hatched. In reality the eggs did not hatch and the young usually die because the mother is not there to incubate the eggs.
What do prairie chickens eat?

Taberville Prairie is a remnant of the prairie ecosystem that once covered more than one-quarter of Missouri.
Why are prairie birds declining?
Loss of suitable habitat is one of the largest reasons for this species’ decline. Without substantial increases in suitable habitat, the species, which once numbered in the hundreds of thousands in our state, will likely soon be extirpated. Prairie conservation is the key to their survival.
What color are Greater Prairie Chickens?
Adult greater prairie-chickens are barred with brown, tan, and rust colors throughout and are similar in size to a small domestic chicken. The tail is short and rounded at the tip. There are tufts of long feathers on the sides of the neck; these tufts are longer in males.

Length: 17 inches (tip of bill to tip of tail).
What is the Prairie Chicken Conservation Plan?
A rangewide prairie-chicken conservation plan administered by WAFWA includes a mitigation program in which oil and gas companies can pay landowners to improve habitat on their property to offset any loss of habitat the companies cause. But Greenwald and others say the 2013 plan —created, according to its introduction, to avoid a listing “while facilitating continued and uninterrupted economic activity”—is too soft on industry. The Permian Basin Petroleum Association was among the interests that helped create the rangewide plan—the same group that later got the threatened listing overturned by pointing to the protections in the plan.
How many prairie chickens are left?
Today, however, only around 34,000 Lesser Prairie-Chickens remain, spread across parts of Colorado, Kansas, New Mexico, Oklahoma, and Texas. They’ve lost 84 percent of their original habitat, much of it converted to croplands, oil and gas fields, wind farms, and other types of development. What remains is largely unprotected—95 percent of it is private land—and is expected to become intolerably hot and dry due to climate change, increasing the likelihood of nest failures like what Grisham witnessed. “My fear,” he says, “is that we’re getting to the breaking point of where the species can’t keep up with our actions.”
What happens if the government lists chickens?
If the government lists the chicken, it won’t be for the first time —the FWS deemed it threatened in 2014. But the following year a federal judge overturned the listing, siding with the Permian Basin Petroleum Association and some oil-producing New Mexico counties. Their lawsuit argued that the agency had overlooked existing conservation programs that obviated the need for invoking the Act. Environmental groups petitioned again in 2016 for the bird to be listed and later sued over what they described as inaction by the Trump administration. That led to a settlement with the FWS in 2019 that requires the agency to make a new listing decision this month.

Who is the executive director of Audubon Southwest?
The energy industry played “an outsize role in those negotiations,” says Jon Hayes , executive director of Audubon Southwest, resulting in “a plan that probably didn’t do enough for the bird.”
How many prairie chickens were released in 2007?
Still, for a long time, it seemed that whatever the recovery team did, the chicks’ survival rate in the wild remained dismally low. From 1995 to 2007, 1,185 prairie chickens hatched in captivity were released.
How long did Attwater chicks stay in the wild?
In 1995, the recovery team tried releasing a group of Attwater’s chicks bred in captivity into the wild, keeping them at first for 14 days in an outdoor pen, so that they could acclimate to their new environment, and then sending them out on their own into the prairie grasses. But right away there were problems.
What did Bailey say about endangered species?
Bailey said that in working with endangered species, “you tend not to hear a lot about it until you get the good stories. You don’t necessarily always hear about the 15 years of pain before you got the successful releases or the nesting in the wild.”. Mr. Rossignol, for one, has not given up.
How long do prairie chickens live?
In the wild, the prairie chicken, a relatively small grouse with brown and tan feathers and a turkeylike tail, has a brief life span: An adult bird, if it is lucky, might live two years. Very young chicks can easily succumb to heavy rain or unusual heat, their bodies unable to regulate temperature until they are older.
What happened to the birds when they died in a release pen?
When a bird died in a release pen, it spread botulism to the other chickens that had pecked at the carcass, killing many of them. Even getting the birds to breed in captivity was far from easy.
How much does it cost to get rid of Attwater chickens?
The plan estimates that the recovery would cost about $192 million over 50 years.
What animal swooped in and frightened the chicks?
But several years later, they checked one of the acclimation pens and found that the young chicks inside had been decapitated. A great horned owl had apparently swooped in and frightened the chicks. Mr. Rossignol said the chicks may have stuck their heads up through the netting, only to have them lopped off by the owl.
How many Attwater chickens were there in 1994?
Their population has declined dramatically since 1993, when an estimated 456 Attwater prairie chickens existed in the wild. In 1994, that estimate dropped to 158 birds, and by 1996, only 42 of these rare birds were left.
Why are prairie chickens endangered?
Prairie chickens are endangered because the tallgrass prairie has been plowed for farmland and covered by cities. Habitat has also been lost because of heavy grazing by cattle, although some cattle ranches maintain good grassland habitat suitable for prairie chickens.
How big is an Attwater's Prairie Chicken?
The Attwater's prairie chicken is a small, brown bird about 17 inches long, with short, rounded, dark tail. Males have large orange air sacs on the sides of their necks. During mating season, males make a "booming" sound, amplified by inflating the air sacs on their necks, that can be heard 1/2 mile away.
Where do Attwater chickens live?
Attwater's prairie chickens live on coastal prairie grasslands with tall grasses such as little bluestem, Indian grass, and switchgrass. The birds like a variety of tall and short grasses in their habitat. They gather to choose a mate in an area of bare ground or short grass where the males can be easily seen by the females. This is called a "booming groundor lek." The males dance and make a booming noise to attract the females. Hens build their nest in tallgrass and usually lay 12 eggs during nesting season. The eggs hatch in April or May. Small green leaves, seeds, and insects form the diet of the Attwater's prairie chicken. Attwater's prairie chickens live about 2-3 years in the wild.
When do hens lay eggs in Attwater?

Characteristics
- Prairie-chickens are distinguished from other grouse such as Greater Sage-Grouse by the male prairie-chicken's long neck feathers, called pinnae, which flare and resemble horns during their elaborate courting displays. Greater Prairie-Chickens can be distinguished from Lesser by their vocalization (booming rather than gobbling), larger size, and darker brown color, as well as yello…
Behavior
- Greater Prairie-Chickens are non-migratory and spend their entire lives within the few remaining remnants of tallgrass prairie habitat, particularly places where native prairie is interspersed with agricultural fields. During its elaborate display, the male dances and struts with his head low and wings held stiffly at his sides, pinnae flared and gular sacs inflated. He may jump into the air wit…
Diet
- These birds are strong flyers and may commute up to 30 miles in search of wintering grounds with a reliable food source. They consume leaves of prairie plants, seeds, buds, and insects.
Reproduction
- The prairie-chicken breeding season begins in early spring and continues until June. Males establish a communal booming ground in a flat, raised territory with short grass, where eight to 20 males display together and boom to attract females. Males fight among themselves for territories on the lek; these territories may be as small as 20 or 30 feet across, and one or two males usuall…
Breeding
- Male prairie-chickens stay on their display grounds for almost two months; after mating, they have no further role in nest-building or chick rearing. Females disperse from the lek and build their nests on the ground in thick grass, laying between four and 15 eggs per clutch and incubating them for around 26 days. The hatching period peaks from late May to early June, when insect po…
Conservation status
- After decades of decline, the Greater Prairie-Chicken has disappeared from a number of states, including Indiana and Kentucky, where it was once common. Although remaining populations appear stable, the species is still at risk, particularly from genetic isolation resulting from its highly fragmented habitat: In-breeding among a small population reduces fitness and fertility, and was …
Projects
- ABC is working with partners at the state and local level on projects that benefit both grassland birds and monarch butterfiies, as well as with ranchers to implement sustainable grazing practices on grasslands. This work can benefit prairie-chickens and other birds found in similar habitat such as Common Nighthawk and Long-billed Curlew.
Overview
The greater prairie chicken or pinnated grouse (Tympanuchus cupido), sometimes called a boomer, is a large bird in the grouse family. This North American species was once abundant, but has become extremely rare and extirpated over much of its range due to habitat loss. Conservation measures are underway to ensure the sustainability of existing small populations. One o…

Subspecies
There are three subspecies;
• The heath hen, Tympanuchus cupido cupido, which was historically found along the Atlantic coast, is extinct. It was possibly a distinct species; in this case the two other forms would be T. pinnatus pinnatus and T. p. attwateri.
• Attwater's prairie chicken, T. c. attwateri is endangered and restricted to coastal Texas.
Population and habitat
Greater prairie chickens prefer undisturbed prairie and were originally found in tallgrass prairies. They can tolerate agricultural land mixed with prairie, but fewer prairie chickens are found in areas that are more agricultural. Their diet consists primarily of seeds and fruit, but during the summer they also eat green plants and insects such as grasshoppers, crickets, and beetles. These birds were once widespread all across the oak savanna and tall grass prairie ecosystem.
Threats
Greater prairie chickens are not threatened by severe winter weather. When the snow is thick they "dive" into the snow to keep warm. A greater threat to the prairie chickens comes in the form of spring rains. These sometimes drenching rains can wreak havoc on their chicks. Another major natural threat is drought. A drought can destroy food and make it difficult for the chicks.
Human interactions are by far the greatest threat. The conversion of native prairie to cropland is …
Sexual behavior
Greater prairie chickens do not migrate. They are territorial birds and often defend their booming grounds. These booming grounds are the area in which they perform their displays in hopes of attracting females. Their displays consist of inflating air sacs located on the side of their neck and snapping their tails. These booming grounds usually have very short or no vegetation. The male pr…
