• Greater sage-grouse strut display

    Male greater sage-grouse strut displays on a lek near Hudson, Wyoming USA. During the spring, males gather on breeding grounds, called leks. Males perform strut displays to court females and define their display territories on the lek. The "burp" sounds occur when males inhale or exhale air from their vocal sac (they inflate their esophagus with air, which we see protruding through 2 colorful regions on their chest during display). A few attractive males will mate with almost all of the females who visit the lek, and most males will not mate at all. Females raise the young on their own.

    Sage-grouse are sensitive to human disturbance and easily spooked! If you're interested in observing a sage-grouse lek, contact your local wildlife managers (Bureau of Land Management or state wildlife agency) to learn which leks to visit and how to minimize your impact on the birds.
