Hybridization of greater and lesser prairie-chicken is uncommon but well established in the western part of Kansas where their ranges overlap.
Hybrid prairie-chickens have intermediate characteristics of both species in appearance and booming display behaviors. The greater have darker coloration than the lesser, and the hybrids are in-between. Hybrids also have intermediate vocalizations of both greater and lesser prairie-chickens, combining booming and gobbling.
It appears that in most cases, females of both species do not recognize hybrid males as a mate and ignore them on the lek.
