The California Naturalist






David Wimpfheimer, is a biologist, professional naturalist and guide with a passion for birds and the natural history of the West. Since the mid-1980s, David has shared a great deal of information about all aspects of the natural world with hundreds of groups.
From birding classes to whale watching expeditions to natural history hikes, David takes great pleasure in guiding people on tours of discovery and exploration. David's seasoned focus and knowledge, make for an enjoyable and educational outing. Along with the intended, nature's unpredictability might present you with the unexpected excitement of a unique bird behavior; or a mammalian critter, such as a hunting bobcat or meandering coyote. Lizards, butterflies, trees, lichen, fungi and even paw prints may be in your path. With David's patient guidance, you will receive many views and explanations for all these outdoor wonders.
David's nature excursions are from a generalist's point of view. Even though David is most passionate about birds and the majority of his excursions are geared toward teaching and interpreting the language of the avian world; he is just as comfortable and enthusiastic teaching about all the wonders of nature.
