Sage grouse struts his stuff
Like gyms or bars, lekking grounds are social performance spaces, where males spread their tail-feathers, inflate their impressive chests, and strut about, calling amorously to the lady birds. Ecologist Gail Patricelli of UC Davis captured this video of a lek near Hudson, Wyoming. US Fish and Wildlife Service named the grouse’s habitat, the Great Plains sage-steppe, one of the most imperiled ecosystems in America.
