Greater Prairie Chicken - Subspecies

Subspecies

There are three subspecies;

• The Heath Hen, Tympanuchus cupido cupido, which was historically found along the Atlantic coast is extinct. It was possibly a distinct species; in this case the two other forms would be T. pinnatus pinnatus and T. p. attwateri.
• Attwater's Prairie Chicken, T. c. attwateri is endangered and restricted to coastal Texas.
• The Greater Prairie Chicken, T. c. pinnatus, is now restricted to a small section of its former range.
