Fall Pot-luck

This year's Fall Pot-luck is taking a slightly different form, and we hope you enjoy it. In an effort to get to know our YAMS youngsters better, we are planning a combined event: Geezers and Fledglings together. So join us for a Fall Pot-luck and Pizza Party featuring the Ancient Murrelets vs. Young Ancient Murrelets Bird-a-thon around Spring Lake, Saturday, September 13, 2:30 to 5 PM. Here's the plan: We'll gather at the picnic tables at Lower Oak Knolls Picnic area (38.4496804, -122.6507955). Take the Newanga Avenue entrance and follow signs to Lower Oak Knolls. From parking lot, look for brightly colored table cloths and signs locating our tables. RROS members please bring a pot-luck plate - salad, main or dessert, to share, to accompany marvelous Mary's Pizzas. Its useful to bring your own utensils, beverages, and camping chairs. Lisa and Liz will organize the teams (old geezers and young bucks) which will circumnavigate the lake in different directions and return to the tables for a tally, prizes, pizza and more. A very short business meeting will follow as this event replaces our usual Sugarloaf pot-luck event. Start the new birding year off right, and join the fun.

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 Ruth Rudesill by email at ruthier@sonic.net or text at (707) 337-6516.

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

Wednesday Wanderings

This is a new opportunity to bird with RROS starting this year. One of our members will take us on a relaxed bird walk at their local patch or favorite place. These will be at a more casual pace, social, and perfect for new birders.

YAMS Field Trips

These outings are for the young members of YAMS and their guardians only. All field trips meet at 8:30am at the site unless otherwise denoted. Many are half-day excursions ending at 12:30pm with a group lunch and field trip bird list compilation.  Some are all-day excursions. As always, bring binoculars, water, snacks, lunch, plenty of layered clothing, and field guides.
