Grand Teton National Park ranger naturalists have begun their early-morning tours to observe strutting sage grouse performing their annual courtship dance on an historic lek located just off the Antelope Flats Road near Mormon Row. Strutting grouse trips are being offered beginning this weekend. Ranger-led excursions offer an exceptional opportunity to witness this unique springtime ritual as sage grouse congregate and perform animated courtship displays. While participants view the antics of strutting grouse, rangers will provide information about their natural history and various conservation efforts underway for sage grouse populations that have declined throughout much of the American West. Sage grouse tours begin from the Craig Thomas Discovery and Visitor Center at 5:30 a.m. and reservations are required.
