MDBA Field Trip -- Pt. Pinole: Shorebirds in the Shade
2025-07-08 10:00 - 13:30 (America/Los_Angeles) | Point Pinole Regional Shoreline (Giant Hwy parking lot), 5551 Giant Highway, Richmond, CA, 94806
We’ll search for shorebirds in the shade of the fragrant eucalyptus groves that line the shores of Pt. Pinole Regional Park. July marks the beginning of shorebird migration: peeps, plovers, and more are starting to trickle back in from the north. We’ll scan the beach as the tide rises for shorebirds and marine ducks. The park can also yield surprises, like the Bobolink that lingered there last fall.
The trail is narrow, dusty, and rocky at points. There are not many places to sit and rest along the way. There is a bathroom and water fountain at the trailhead. Bring plenty of water and sunscreen. Please factor in the potential for westbound traffic when planning your departure.
Trail Rating: 2

MDBA Field Trip -- Lafayette Lakeside Loop
2025-07-21 18:30 - 21:00 | Lafayette Reservoir, 3849 Mount Diablo Blvd, Lafayette, CA, 94563
Unwind after a hard day’s work at the beautiful Lafayette Reservoir. Tucked into the hills between the coast and interior Contra Costa County, the reservoir’s forested hills are home to many pine-oak residents like Spotted Towhees, Red-shouldered Hawks, and Band-tailed Pigeons. The iconic 100-year-old, 170-foot-tall outlet tower in the center of the reservoir attracts many cormorants and the marshes around the edge often harbor herons. We may even get lucky enough to see a flock of American White Pelicans.
We’ll walk the 3-mile, paved Lafayette Reservoir Trail that circles the reservoir to see what’s out there. Parking is $2/hr or $7/day. Please factor in northbound and eastbound traffic when planning your departure.
Trail Rating: 2 – Over 2 miles walking with a couple of short steep climbs.

7:30 PM Main Program: Lime Ridge Open Space
*as a conservation organization we encourage you to bring your own mug for coffee or tea
Ron Graydon’s program on Lime Ridge Open Space will focus on the Northern Concord section of the Lime Ridge Open Space. It will include the geologic formation of the Diablo Range, and specifically Lime Ridge. The program will also include the human history of the Diablo Valley, including Lime Ridge, human impact, natural history and ecology. Finally, Ron will discuss the Friends of Lime Ridge, and their efforts toward ecological restoration.
Ron Graydon has over fifty years experience in environmental education and activism. Ron has a B.S. degree in Conservation of Natural Resources, an interdisciplinary environmental major, from U.C. Berkeley, with an emphasis in environmental education and impact analysis.
Upon retirement Ron hiked almost daily near his home at Lime Ridge Open Space in Concord. He was consequently inspired to form the Friends of Lime Ridge, which is a volunteer group involved with the ecological restoration of the park. They have planted about seventy-five Oak and Buckeye trees, developed three native plant gardens, installed four Bluebird nesting boxes, and conducted park clean ups, nature walks, and invasive plant removals.

MDBA Field Trip -- Coyote Hills, Fremont
2025-09-21 08:30 - 12:30 | Coyote Hills Regional Park, 8000 Patterson Ranch Road, Fremont, CA, 94555
Ducks & Peeps!
This morning walk will take us on multiple trails within the beloved Coyote Hills Regional Park complex to search for southbound, migrating shorebirds and inbound, wintering waterfowl. We’ll first check out the reedy margins of the marshes on Chochenyo and Muskrat trails, keeping an eye out for chatty Common Yellowthroats and Marsh Wrens, and maybe even a secretive rail. Then, we’ll cross the scrubby hills of Lizard Rock Trail, where White-tailed Kites are not uncommon, on our way to Bayview Trail. The trail is only a few yards away from the salt marsh evaporation ponds–the perfect place to search for flocks of migrating shorebirds. Some luck and a bit of scoping may even yield rarer species such as Snowy Plovers.
Shorebird ID can be both challenging and rewarding. This walk is especially good for intermediate birders looking to gain more experience with this tricky taxon, but as always, all skill levels are welcome!
Scopes are useful here. Carpooling is encouraged.
The trail is mostly unpaved and there is only one restroom at the trailhead. At this time of year it can be cool and windy, or hot by mid-day. Please bring plenty of water, sunscreen, an extra layer (it can be cold and windy), a snack, and any other equipment you need for hiking.

Paul’s program is based upon his new book, “Woodpecker: A Year in the Life of North American Woodpeckers”. In both, award-winning photographer Paul Bannick uses his intimate yet dramatic images, up-to-date science and first hand narratives to explore the lives of North American Woodpeckers through four seasons including: courtship, mating, and nesting in spring; fledging and feeding of young in summer; dispersal and learning independence in fall; and, finally winter movements and survival. His exploration of these impactful birds and their habitats includes the species from the Arctic through southern Mexico, including those of the Caribbean Islands.
Bannick’s startling images reflect their shared behaviors as well as some surprising exceptions and adaptations. More than just a backdrop, the varied habitats—reveal wildly rich stories of their own.“Woodpecker: A Year in the Live of North American Woodpeckers” is a stunning follow-up to Bannick’s award-winning title, “Owl: A Year in the Lives of North American Owls”, giving bird lovers yet another gorgeous photographic tribute, engaging natural history, and a compelling call to preserve the habitats that sustain these most iconic of birds.Paul Bannick is an award-winning author and photographer who makes images to inspire education and conservation.

*as a conservation organization we encourage you to bring your own mug for coffee or tea
Veronica Cornett of the Pacific Flyway Fund will share information about the development of the new Pacific Flyway Center, which will be located in the Suisun Marsh in Fairfield, California. The Pacific Flyway is one of four bird migration routes in North America. The Pacific Flyway Center will be front and center for this significant stopover on the north-south migration path for birds that stretches from Alaska to Patagonia. The Center will sit in the middle of this migratory corridor, allowing every visitor an opportunity to see a great number of waterfowl and shorebirds, as well as other wetland-dependent species.
Fifteen newly created wetlands and surrounded by grasslands will serve as the Center’s primary classroom, providing a vivid and engaging education environment that is home to hundreds of species of native plants and animals. In the future the Education Center will complement the experience with interactive displays that highlight the importance of biodiversity and ecosystems. The Center will stand as an example of wildlife and wetland stewardship, preserving this ecological wonder for generations to come, and fulfilling Ken Hofmann’s vision to do something good for the Planet.

**Sorry, this event has been CANCELLED by MVSD.**
This field trip is very suitable for beginning birders! Binoculars are available for borrowing, just let the leader know in advance to bring an extra pair.
Moorhen Marsh, maintained by the Mt. View Sanitary District in Martinez is of the first water treatment facilities in the US that was designed to offer quality habitat for migrating birds. The marsh is usually only open for visits by appointment, Monday thru Friday, so this is an unusual chance to visit on a Saturday. We hope to see resident and overwintering ducks geese, herons, and passerines.
Just across the freeway, McNabney Marsh, a.k.a Waterbird Regional Preserve, hosts many more waterbirds and shorebirds as well. Marsh passerines and raptors might also be present.
We’ll meet at the observation deck near the south end of McNabney Marsh, off Arthur Road, and scan with our scopes. After that we’ll move the cars a short distance and take a walk around the artificial marshes operated by Mt. View Sanitary District.
Hike Rating: 1 – Easy. Under 1 mile on flat terrain. Paths are unpaved paths and potentially muddy, if it’s rained recently.

2025-11-30 08:30 - 13:00 | Los Vaqueros Reservoir, 121 Walnut Blvd, Brentwood, CA, 94513
Los Vaqueros Reservoir is a relatively remote area overseen by the Contra Costa Water District. The open savannah surrounding the reservoir is one of the best places to observe grassland species such as American Kestrels, Meadowlarks, Horned Larks, and Prairie Falcons. Rarities like Mountain Bluebird, Lewis’ Woodpeckers, and Burrowing Owl occasionally show up there as well. We’ll explore Kit Fox Trail and, if time permits, maybe the dam area, too.
This trip requires more hiking than most of our outings. The trail is mostly unpaved and there is only one restroom at the trailhead. Please bring lots of water, sunscreen (there is little shade on the trail), an extra layer (it will almost certainly be cold and possibly windy), a snack, and any other equipment you need to hike. Plan accordingly.
Scopes are helpful here. The trip leader will have one to share, and if you have one of your own feel free to bring it.

Bring your inner child to the December program as Constance Anderson discusses her newest book, So Many Ways To Be a Bird. As an award finalist for children’s non-fiction, this book explores the surprising world of bird adaptation, where each egg, beak, and wing has a unique story.
The book reveals how birds have brilliantly adapted to a changing environment over time, resulting in an incredible variety of sizes, colors, wings, nests, eggs, beaks, feet, and feathers. Constance’s vibrant collage illustrations help readers identify birds and inspire a desire to protect them.
So Many Ways To Be a Bird follows Constance’s previous titles: A Stick Until, a picture book and science journal about animal tool use; and Smelling Sunshine, which celebrates the connection between people of diverse backgrounds through the simple act of hanging laundry with a loved one.
Join us as author, illustrator, and naturalist Constance Anderson shares her love of birds and her desire to connect people to one another and the environment.

The Importance of Islands to Avian Evolution

7:30 PM Main Program: The Importance of Islands to Avian Evolution
*as a conservation organization we encourage you to bring your own mug for coffee or tea

Islands play a pivotal role in both the evolution of new avian species and the extinction of others. Because islands are isolated landmasses, species that arrive there evolve separately from their parent groups, eventually becoming unique through genetic drift. However, because island species are restricted to small areas with limited populations, they are highly susceptible to natural disasters—such as hurricanes, volcanic eruptions, tsunamis, and rising sea levels—as well as human-caused pressures. This talk focuses on the issues unique to islands and how we might protect these vulnerable species.

Bob has taught birding classes in the Bay Area for over 25 years and is an avid traveler, specifically seeking out islands in search of birds. He is a board member of the Farallon Islands Foundation, an organization dedicated to fostering life on islands. He has visited many of the world’s major biodiversity hotspots, including Madagascar, Borneo, Hawaii, Indonesia, New Guinea, New Zealand, and Cuba.

MDBA Field Trip -- Woodbridge Road & Sandhill Crane Fly-In
2026-01-25 15:30 - 18:00 | Woodbridge Ecological Reserve, 7730 W Woodbridge Rd, Lodi, CA, 95242
This outing is especially suitable for people with mobility issues.
A very special trip arranged with the California Department of Fish and Wildlife. At 3:45 PM we’ll meet their volunteer docents at the South Unit of the Woodbridge Ecological Reserve, near Lodi, where they will introduce us to the many waterfowl and shorebirds that winter in the area.
About 90 minutes before sunset, we will move over to the blinds that overlook the roosting area for Sandhill Cranes. We’ll be able to sit and watch as hundreds of cranes fly in for the evening. It’s a spectacular event!
This trip is open to all MDBA members of any birding level of experience, and especially suitable for those with mobility issues. The platform overlooking the ponds at the South Unit—our first stop—is about 40 yards from the handicapped parking spots, up a short, accessible ramp. The blinds where we’ll sit and watch the cranes fly in are also just a short walk over level ground from the parking spots. There are toilets at the South Unit (and I think at the North Unit too, though I’m not sure.)
MDBA trip coordinator Matt Tarlach plans to drive a carpool to accommodate any member who doesn’t want to drive this distance (Woodbridge Reserve is a little over an hour from Heather Farm), or drive back after dark. If you would like to ride with this group, please email ASAP after signing up, so he knows how many would like to join the carpool. We may rent a minivan or other vehicle, depending on what’s needed.
Leader: Matt Tarlach, MDBAFieldtrips@gmail.com
Hike Rating: 0. A few very short walks over flat terrain.
Meet: Carpool will meet at Heather Farm. If driving on your own, meet at 3:45 at the South Unit of Woodbridge Ecological Reserve
GPS for the meeting point: 38.15775478150474, -121.44355433233056
Trip goes rain or shine. The blinds are open and unheated, so dress to sit outdoors until after sunset, about 90 minutes.
There is room in the blinds for about 25 people but parking for only about 14 cars. Plan to drive with a friend, or to share a casual carpool with another member.
Due to the capacity limit and expected strong interest, this trip is for MDBA members only. Members may bring a guest; if you’d like to bring more than one guest please email the leader before booking. If you may bring children, please consider the need to sit quietly outdoors, on a cool evening, for over an hour.
There is no charge by MDBA for this event—including for the carpool, if needed. However, every attendee must have a Lands Pass from the CA DFW: https://wildlife.ca.gov/Licensing/Lands-Pass
Sign up at the link below. And if the outing is ‘Sold Out’, please join the waitlist! There are usually some cancellations from the early bookings:

7:30 PM Main Program: Alcatraz Island – A Climate Refuge for Seabirds
*as a conservation organization we encourage you to bring your own mug for coffee or tea

Alcatraz Island’s Brandt’s Cormorants moved into San Francisco Bay in the early 1990s during a coastward population shift. Alcatraz is now one of the largest Brandt’s Cormorant breeding colonies, and one of only two estuarine colonies. Alcatraz seabirds, including Pigeon Guillemots and Western Gulls, have been outperforming their ocean counterparts despite a high level of human disturbance in this urban setting. The bay hosts a large anchovy population and demersal fish nursery, with strong tidal currents and the river plume into the ocean concentrating prey for seabirds and other predators. We are working to mitigate anthropogenic stressors to support this important colony and increase seabird resilience to climate change.

Julie Thayer has worked in the California Current marine ecosystem for three decades, with a brief hiatus on the north coast of Brazil. She studied at the University of California at Santa Cruz/Long Marine Lab and UC Davis in Marine Biology and Ecology. Thayer has done field research on Alcatraz seabirds, studying population changes, diet, productivity, and human disturbance since 1997.
