WALNUT CREEK, CA—On August 18, 2024, seven California condors flew north into Alameda and Contra Costa counties on a circuitous aerial tour.
The three-hour flight began shortly after noon, when they left their previous evening’s roost site south of Ohlone Regional Wilderness.
They soared over Pleasanton and Sunol, near the intersection of Highways 580 and 680 and the furthest west the birds have flown in the East Bay. They flew over Dublin and Tassajara.
They ventured north over Mount Diablo’s Pine Canyon near Castle Rock—a possible future nesting site and where Save Mount Diablo previously helped reestablish endangered peregrine falcons—and as far north as Lime Ridge Open Space west of Clayton before veering east—the furthest north the birds have flown in Contra Costa County.
