Irvine Ranch Natural Landmarks

Birds are often hidden from sight and yet can still be identified by their calls and songs. Knowing how to identify birds by ear is an important step in becoming a better birder. Join other birders as we search for birds by both ear and eye in the beautiful arroyo canyon of Agua Chinon, part of OC Parks’ Irvine Ranch Open Space. Restoration of this sensitive habitat has recently been completed, and we are watching to see if bird populations increase over time. Please wear sturdy shoes suitable for hiking, along with sun protection such as a hat and sunscreen.
