Kern River Valley Professional Review and Guide
"Kern River Valley must be counted as one of the best birding sites in California because of its diversity. The South Fork of the Kern River supports the largest remaining stand of Great Valley cottonwood-willow riparian forest in California, and has been designated a Globally Important Bird Area, because it is a major migration path for Turkey Vultures (28,000 per year), because of its breeding southwestern Willow Flycatchers (federally endangered species), and because almost the entire world population of Kern Red-winged Blackbird (a subspecies of Redwinged) is located in the valley. A total of 318 species of birds have been recorded in the valley, with 2,000 species of plants (almost a third of the flora of California) and 115 mammals (the highest diversity in the United States) in the immediate area. In 1997 National Audubon Society—California took over the management of the Kern River Preserve from The Nature Conservancy.
