Field Trips
Marin Audubon Society is providing a full schedule of free field trips for the 2024 season.
Advance registration is required for most of our trips, nearly all which have size limits to prevent overcrowding. Registration on the MAS website’s Field Trips page will open ten days before the trip date.
Trips can fill up quickly. Please register early to make sure you get a spot. If you won’t be able to attend a trip that you have registered for, please cancel using the “contact organizer” button on Ticketbud so that the spot may be opened up for someone else.
Attention: Recently Ticketbud has not opened for trip signups precisely at 8:00AM. This has led to confusion among would be participants who assumed the message “There are no tickets available at this time” means the trip is already sold out, but it doesn’t, so please try to sign up again a minute or two later. Ticketbud is working on the problem.
Our field trips are free to our members and the public, but we greatly appreciate your donations to support our programs and conservation projects! A donation of $35 or more qualifies you for an annual membership at Marin Audubon Society! **New Members Only

The Ponds at Las Gallinas Sanitary District – MAY
Thursday, May 2, 2023 8:30 AM to 12:00 PM Birding with Sande and Bob Chilvers All participants are welcome to join this trip. No registration required. Beginning birders are especially welcome on the first Thursday of each month for a leisurely walk around the Las Gallinas ponds. Join our friendly leaders as we search for waterfowl, waders, songbirds, raptors, and shorebirds. Bird enthusiasts of all levels help each other to find and identify the birds, and there are usually several experienced birders to assist. You don’t even have to arrive on time because we spend the first 30 – 60 minutes studying the birds around the first pond and the group is easy to find. Heavy rain cancels. DIRECTIONS: From Hwy 101, exit at Smith Ranch Rd. Drive east on Smith Ranch Rd toward McInnis Park. Turn left immediately 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 an outhouse in the parking area for public use.

Big Rock and Las Gallinas – Birding in Marin Series

8:30 AM to mid-afternoon
Birding with Jim White and Bob Battagin
Register HERE for this Field Trip
Registration required for this trip. Registration opens on May 22 at 8:00 AM.
Trails at Big Rock, rather steep, allow us to view some of the expansive grasslands and forested ravines in Marin. Some of the grassland nesting birds we will be looking for include Lazuli Bunting, Grasshopper Sparrow, Horned Lark, and Ash-throated Flycatcher. We will also have a vast amount of sky visible so swallows, swifts, and raptors may appear with a chance for a Golden Eagle.
At midday we expect to drive Lucas Valley Road to Las Gallinas where we will be looking for American and Least Bitterns, Green Heron, Cinnamon Teal, Common Gallinule, and Great-tailed Grackle.
