Western Burrowing Owls (Athene cunicularia hypugaea) have undergone substantial long-term declines in coastal Southern California, and breeding populations are now considered ecologically extirpated in Orange County. In October 2024, the California Fish and Game Commission advanced the subspecies to candidate status under the California Endangered Species Act (CESA), reflecting heightened concern over statewide trends and threats. Against this backdrop, we report eight years of winter monitoring at Fairview Park (Costa Mesa, CA) documenting recurring use by non-breeding Burrowing Owls. Color-banding and resight data indicate winter site fidelity by at least one individual across successive winters, consistent with local observations and agency communications about the park’s overwintering owls. In 2024 we deployed GSM transmitters on two overwintering owls; one individual’s northbound movement was tracked to a summer residency near Brogan, Oregon, providing a concrete link between Orange County wintering habitat and interior Northwest breeding grounds. These findings clarify the functional role of Fairview Park as winter habitat in a county without a resident breeding population, and they highlight management priorities: protect and enhance winter roost/foraging structure, integrate cultural stewardship and trail management, and coordinate across jurisdictions to conserve connected breeding landscapes. We discuss monitoring design (band-resight, GSM duty cycles), data limitations, and policy implications under CESA candidacy for conserving a small but persistent winter assemblage.
