RROS Field Trips

You do not need to be a member to attend our trips. We’d love you to join RROS (we could use the money), but come out with us anyway.

There are no reservations required, though you are encouraged to RSVP for all trips. If you RSVP you will automatically be shared on the group eBird list. To RSVP, contact Garrett Pierce by email at garrettallenpierce@gmail.com or text at (415) 260-7406.

Some field trips will be limited due to vehicle accessibility or physical constraints.
