Cool Facts
- Like many other grouse species, the Greater Sage-Grouse
male plays no role in the raising of the young. Males display
on dancing grounds known as leks. Females visit the leks
to obtain matings, and then go off to raise their brood
by themselves.
- Traditional lekking grounds may be used for years.
- Although many male Greater Sage-Grouse may display
at a lek, only one or two males get picked by a majority
of the females for mating.
