Female sage-grouse walking in the sagebrush

The greater sage-grouse (hereafter sage-grouse) are a large ground dwelling bird.  They can be up to 30 inches long and two feet tall, weighing from two to seven pounds. Females are mottled brown, black, and white which serves as camouflage from predators. Males are larger and more colorful than females with white feathers around the neck and bright yellow air sacs on their breast, which they inflate during their mating display. The birds occur at elevations ranging from 4,000 to over 9,000 feet and are dependent on sagebrush for cover and food.  

Counting sage-grouse at leks

Research in the Bi-State has set the stage for some of the research that has occurred rangewide for the greater sage-grouse. 

Much of the research has been led by the United States Geological Survey (USGS) at the Western Ecological Research Center. 

A summary of research through 2012 can be found in the BSAP on page 9. Below is a list of relevant research completed in the Bi-State and links to the papers where available.
