The greater sage-grouse (Centrocercus urophasianus) puts on a bold display during mating season. To help prevent collisions with aircraft, park officials at Grand Teton National Park have deployed papier-mâché sage-grouse in a field south of the airport’s runway. NPS teamed up with the Teton Raptor Center, Jackson Hole Middle School art students, and local artist Lori Solem to create the four hand-crafted papier-mâché birds. NallThe greater sage-grouse can be found in the western United States and Canada. The North American Breeding Bird Survey estimates that since the 1960s, greater sage-grouse populations have declined steadily by an average of 2.3 percent each year.
