Summary

In San Mateo County parks and the San Francisco Fish and Game Refuge, feeding, hunting, trapping or disturbing any wild bird or other wildlife is banned under the county's park rules.

City-specific rules exist: Redwood City has its own bird protection rules that differ from San Mateo County's county-level regulations. If you live in Redwood City, check the city-specific page instead.

All County Parks and Recreation Areas and the San Francisco Fish and Game Refuge are sanctuaries for wildlife. No person shall feed, approach, disturb, frighten, hunt, trap, capture, wound, kill, chase, pursue, or disturb the natural habitat of, any wild bird, mammal, reptile, fish, amphibian or invertebrate within a County Park or Recreation Area or within any San Francisco Fish and Game Refuge area located within the County, nor shall any person allow any dog to do so.

Full Breakdown

San Mateo County Ordinance Code § 3.68.080(n) designates every County Park, Recreation Area and the San Francisco Fish and Game Refuge as wildlife sanctuaries. No person may feed, approach, disturb, frighten, hunt, trap, capture, wound, kill, chase or pursue any wild bird, mammal, reptile, fish, amphibian or invertebrate there, and dog owners are equally liable. The Parks and Recreation Department enforces the rule; it applies only inside county park and refuge boundaries, not to birds on private property elsewhere in the unincorporated county.

Violations & Fines

Violating the wildlife protection rule is a misdemeanor under the code's general penalty section, punishable by up to a $500 fine, six months in county jail, or both (§ 1.08.010(a)).
