Audubon Canyon Ranch protects our natural and human communities through land preservation, nature education, and conservation science.

Features and News

We were thrilled to welcome the ABC7News team on our search for mountain lions in the hills of Sonoma. WATCH VIDEO and learn about the fourth mountain lion to be collared in four months.
We humans have come up with some poetic collective nouns for animals. A murder of crows. A parliament of owls. So it seems we missed the proverbial lily pad when we describe the millions of frogs that welcome spring with their delightful chorus.
ACR staff and volunteers conducted the second of four annual waterbird counts on Tomales Bay in mid-January and were surprised by sighting of Caspian terns and one black scoter.
