Description of the Bird
Several very large male grouse displaying. Large white collar ruff and yellow sacs identify them as Sage-Grouse. The much denser and longer filoplumes at the back of the head identify them as Gunnison Sage-Grouse and not Greater Sage-Grouse. Two females approached the lek towards the end of viewing, but didn't seem too interested.
Similar Species Discussion
Greater Sage-Grouse eliminated by the denser and longer filoplumes. All other Colorado grouse eliminated by the very large size.
Previous Experience
First time seeing this species, but had seen Greater Sage-Grouse twice before.
