Overview
The lesser prairie-chicken is a medium-sized grouse of the southern Great Plains — a bird of sand sagebrush flats and shortgrass expanses whose spring lekking display is one of the more dramatic wildlife spectacles remaining on the Great Plains, if you know where to look and are willing to be there before the sun clears the horizon.
In Colorado, you need to be in the southeastern corner of the state to have any chance of finding one. Baca, Prowers, and Kiowa counties hold what remains of the state’s lesser prairie-chicken population — a small, declining group of birds at the northwestern geographic edge of the species’ range. The core of the range lies to the south and east, across the Oklahoma and Texas panhandles and into Kansas and New Mexico. Colorado’s birds are a fringe population, genetically and geographically distinct, occupying the northern margins of the sand sagebrush prairie that characterizes the best lesser prairie-chicken habitat across the range.
The species was listed as federally threatened effective November 2022, following a complex listing history that included a previous listing vacated by courts in 2015. That decade-long regulatory gap, during which the species had no federal protection, allowed habitat loss and population decline to continue without the consultation requirements and formal jeopardy analysis that ESA listing triggers. The species has lost more than 85% of its historical range and fewer than 30,000 birds are now estimated to exist across all five range states.
Natural History
The lesser prairie-chicken is a grouse, a family defined by its adaptation to open country and its elaborate communal lekking behavior. Males are 38–43 centimeters in length, mottled brown and buff with dark barring that provides effective camouflage against the pale, sandy soils of their preferred habitat. The defining display features are the orange-red esophageal air sacs on either side of the neck, which are inflated and used in the booming, cackling vocalizations of spring lek display. Reddish-orange combs above the eyes are also visible in displaying males. Long pinnate feathers on the neck are erected during display.
Leks — traditional communal display grounds — are used by males every spring, typically on bare or short-grass patches with good visibility in all directions. Females attend leks to evaluate males and mate with dominant individuals. After mating, females disperse to nest in nearby vegetation.
Diet includes insects, seeds, forbs, and the leaves and buds of sand sagebrush and other shrubs. Chicks are heavily dependent on insects for protein in their first weeks. The species shows moderate elevation tolerance but is essentially constrained to the plains — it does not inhabit mountain or foothill landscapes.
Habitat in Colorado
The southeastern Colorado population is associated with the sand sagebrush prairie and short mixed-grass prairie that characterizes the Baca, Prowers, and Kiowa county landscape — a region of sandy soils, scattered sand sagebrush (Artemisia filifolia), blue grama, buffalo grass, and shinnery oak in the sandier areas. This is a distinctive landscape, different in feel and structure from the shortgrass plains north and west of the Arkansas River.
The Colorado population is considered the northwestern edge of the range. Critical habitat has been designated across parts of the range in Colorado and the adjacent range states, covering sand sagebrush prairie that supports the most important remaining populations.
Conservation ranching programs, particularly through the NRCS’s Lesser Prairie-Chicken Initiative, have worked with private landowners across the range — including in Colorado’s southeastern counties — to improve habitat management and reduce disturbance to leks. This type of voluntary, incentive-based landowner engagement is considered a key recovery tool given that most lesser prairie-chicken habitat is on private land.
Threats
Habitat loss and fragmentation has removed or degraded more than 85% of the species’ historical range. Conversion of native prairie to cropland, development, and transformation of sand sagebrush prairie to annual grasslands has fragmented the connected landscape blocks the species requires.
Oil and gas development introduced vertical structure — well pads, roads, tanks, compressors — into otherwise open grassland, providing perching and nesting opportunities for ravens and raptors that prey on prairie-chickens and increasing predation pressure at leks.
Wind energy infrastructure presents similar issues with vertical structures and adds direct mortality risk from turbine collisions and the avoidance behavior that restricts habitat use near wind facilities.
Invasive eastern red cedar (Juniperus virginiana) encroaches into open grasslands across the southern Great Plains, providing perch sites for raptors and altering the open structure that prairie-chickens require.
Drought and climate change drive population fluctuations and are projected to reduce the extent of suitable habitat across the southern Great Plains as temperatures increase and precipitation patterns shift.
Recovery & Conservation
USFWS listed the lesser prairie-chicken as threatened effective November 2022. A recovery plan provides guidance for managing populations across the five range states. The recovery strategy emphasizes maintaining large, connected blocks of native prairie; managing for open structure without vertical elements; and engaging private landowners through NRCS programs, state wildlife agencies, and conservation organizations.
The Candidate Conservation Agreement with Assurances (CCAA) program, developed during the period when the bird lacked federal listing, enrolled substantial acreage of private land in lesser prairie-chicken-friendly management practices. Those agreements continue to provide habitat benefit alongside the current listed status.
What You Can Do
- Report sightings in Baca, Prowers, and Kiowa counties to CPW and eBird. Lek counts and breeding season records from Colorado are valuable for monitoring the state population.
- Support conservation ranching programs and organizations working with private landowners in southeastern Colorado. Native prairie management on private ranch land is the single most important factor in the Colorado population’s persistence.
- Avoid disturbing leks during March through May. Leks are on private land throughout most of the Colorado range; if you learn the location of an active lek, observe from a distance that does not disturb displaying birds.
- Support native prairie protection efforts in the southeastern corner of the state through land trusts and conservation organizations working in the Arkansas River valley and beyond.
