It is similar to the closely related greater sage-grouse (Centrocercus urophasianus) in appearance, but about a third smaller in size, with much thicker plumes behind the head; it also has a less elaborate courtship dance.

[7] The description of C. minimus as a separate species is supported by a molecular study of genetic variation, showing that gene flow between the large-bodied and the small-bodied birds is absent.

Groups of females observe these displays and select the most attractive males with which to mate.

Males perform on leks for several hours in the early morning and evening during the spring.
