The Ponds at the Las Gallinas Valley Sanitary District (LGVSD) – San Rafael
Thursday, November 5, 2026 8:30 AM to noon Birding with Mark Clark Registration is not required. All participants are welcome to join this trip. On this trip we especially welcome beginning birders to join Mark Clark, along with bird enthusiasts of all levels, on our monthly walk around the ponds at Las Gallinas. With fall migration underway, we’ll be looking for waterfowl, waders, songbirds, raptors, rails and swallows. We are likely to spot some interesting species, so come assist in our search. The packed dirt paths around the ponds are wide, flat and easy to navigate. Heavy rain cancels. There is a portable restroom in the parking area for public use. DIRECTIONS: From Hwy 101, exit at Smith Ranch Rd. Drive east on Smith Ranch Rd. toward McInnis Park. Turn left after crossing the railroad tracks and drive about 0.5 mile through the LGVSD gates and into the parking lot at the end of the road. Meet the group by the bridge just past the parking lot. There is a portable restroom in the parking area for public use.

Acorn Woodpeckers: Cooperation, Conflict, and Family Drama
Acorn Woodpeckers, best known for their unique habit of storing acorns by the thousands in special structures known as “granaries”, are cooperative breeders that exhibit one of the most complex social systems of any bird. Based
on a long-term study of this species at Hastings Natural History Reservation in Monterey County,
Walt will explain some of the strikingly cooperative and diabolically competitive behaviors of this species that he and his
colleagues have discovered during their 50+ year field study. -
