Welcome to Central Sierra Audubon Society, which covers both Tuolumne and Calaveras counties. We are a chapter of the National Audubon Society and affiliated with Audubon of California. Central Sierra Audubon supports the mission of the National Audubon Society which is: to conserve and restore natural ecosystems, focusing on birds, other wildlife and their habitats, for the benefit of humanity and the Earth’s biodiversity.
All CSAS trips are open to the public, and all levels of experience are welcome. Beginning birders are encouraged as it’s the best way to learn. Bring drinking water, a lunch and/or snacks. Suggested apparel: sturdy shoes, a sun hat, muted colors. Dress in layers, particularly in winter months. Sunscreen, and insect repellent are advisable for all trips. Bring binoculars, spotting scopes and birding field guides if you have them.

Calaveras and Tuolumne Counties have unique birding opportunities in California due in part to an elevation range of 200 feet to more than 8,000 feet across both counties. Hotspots include everything from low valley / foothill grasslands to towering mountain peaks. The two counties share a border through New Melones Reservoir, the fourth largest in California. Numerous ranch ponds along county roads provide opportunities for wetland birds viewable from the road. U.S. Forest Service land and Calaveras Big Trees State Park are excellent areas to explore.
