San Mateo County Bird Alliance Field Trips

Filoli Field Trip
Pre-registration is required for all field trips!
- Advance registration and field trip size limit: SMCBA is currently requiring RSVPs for all field trips and is limiting the trip size. We are using Eventbrite as our reservation platform. Please no drop-ins.
- Please: Out of respect for our members and community, we ask participants to take sensible precautions for everyone's health when carpooling and sharing spaces. If you're not feeling well, please cancel.
- Participants required to sign liability waivers to participate: SMCBA is now using a electronic Waiver and Photographic Release Form that is sent to participants about a week before the event that is easily signed on your computer, tablet, or smartphone.
- Trip cancellations: If the weather is bad enough that you don't want to go on a field trip that day, chances are your trip leader doesn't want to go either! Field trips will typically be cancelled for heavy rain, but not for light mist.
- Please note that rain or Air Quality Index over 150 cancels, unless otherwise stated. Bring binoculars, water, snacks, sunscreen, and dress in layers as weather can change.
Note: All phone numbers are for Area Code 650, unless otherwise stated.
