• Greater sage-grouse strut display

    256,676 views 7 years ago
    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.
    Filmed with a Sony HDR-FX1 HDV Digital Camcorder.
