Bird-Watching

More than 250 bird species have been spotted in the park, including the sage sparrow, pygmy owl, blue grouse, and mountain bluebird. Park rangers lead free bird-watching walks in Yosemite Valley a few days each week in summer; check at a visitor center or information station for times and locations. Binoculars sometimes are available for loan.
