Fourteen species of woodpeckers have been observed in the Sierra Nevada region, and up to 7 species might be encountered in a single forest. We will explore the lives of Sierra woodpeckers in terms of their physical features that permit them to create holes in trees, their natural history, regional status, and distribution. Holes created by woodpeckers also host an amazing diversity of secondary hole-nesters such as wood ducks, hooded mergansers, small owls, nuthatches, chickadees, creepers, bluebirds, and the introduced European starlings and house sparrows. An optional morning field trip sponsored by Sierra Foothills Audubon will be led by the instructor the Saturday following the class. Materials: $35 optional at class for book.
