Tahquitz Valley

Phil Unitt, curator of the department of birds and mammals at the San Diego Natural History Museum, sets up a mist net to catch avian specimens in Tahquitz Valley. Biologists from the museum are conducting a centennial re-survey of the San Jacinto wilderness. The original expedition in 1908 by UC Berkeley's Museum of Vetebrate Zoology established a benchmark for gauging changes in Southern California’s biological landscape.Myung J. Chun / Los Angeles Times
