Almost a million of them once roamed the coastal prairie of Texas and Louisiana. So they took down the screens and allowed a few scuffles among the males.

Conclusion As of November, , our primary conservation goals have been achieved. In , the yearly count of the birds by the federal Fish and Wildlife Service , which runs the refuge, dipped to 40, an all-time low. A study recorded about 8, Attwater's prairie chickens remaining in four Texas counties. The keepers solved the problem by removing the blinders, allowing the birds to see each other and better simulate the competition of the lek. But several years later, they checked one of the acclimation pens and found that the young chicks inside had been decapitated. Only about 3 in 10 eggs hatch and the others are lost to predators. A tame, captive-raised Greater Prairie-Chicken allows close inspection of her nest. Morrow inspects them like a commander surveying the troops. A captive male Greater Prairie-Chicken courts a female in a naturally vegetated enclosure. From to , 1, prairie chickens hatched in captivity were released. So he decided to test the theory. Rossignol said the chicks may have stuck their heads up through the netting, only to have them lopped off by the owl. Their routines proceed according to clearly delineated steps: an aggressive cackle, a rapid, thumping tap dance, and then the boom —neck sacks inflating, pinnae feathers standing tall as rabbit ears. Morrow doubts there is enough habitat for half that. What happened?
This area is called a lek or "booming ground. Today, only about of these endangered birds remain in the wild on just two remnant prairie fragments in eastern Texas and on experimental release sites on private ranches in the Refugio-Goliad region of south Texas.
Byonly a few dozen chickens remained. Fish and Wildlife Service. Last year, hopes at the refuge ran high, as a group of chicks passed the two-week mark and appeared to be thriving.
Females choose the showiest and most impressive mates—one reason prairie-chickens are so ridiculous looking—and they tend to select carefully.
These endangered birds are found in small numbers in southeast Texas.

They have the potential to drop dramatically from one year to another. These breeders are carefully managed genetically, and their offspring are released annually in at the Attwater Prairie Chicken National Wildlife Refuge in Texas. The barriers were taken down, and the males responded, spending more time strutting and booming and pecking at each other through the fencing. A main objective in the APC Recovery Plan is to increase propagation and release efforts to boost wild populations to self-sustaining levels. The fertility of both sexes is intricately tied to this ritual. As grasslands were consumed by human settlements, industries, agriculture, brushy vegetation, and possibly pesticide use on rice crops, the estimated population of close to one million birds about a century ago plummeted precipitously. The only birds they could find—19 in all—were started in an emergency breeding program.
Today it is considered one of the most endangered birds in North America. Endangered species around the world now number in the tens of thousands: The International Union for Conservation of Nature lists almost 23, plants and animals as threatened with extinction, from charismatic mega-fauna like giant pandas and polar bears to insects and plants that few people have ever heard of.
