MDBA Field Trip -- Putah Creek at Pedrick Road
2025-05-02 07:30 - 14:00 (America/Los_Angeles) | Putah Creek Parking Lot, Putah Creek Parking Lot, Davis, CA, 95616
This delightful, fairly short stretch of Putah Creek (~3/4 miles), can be very productive during Spring migration. It’s a fairly easy walk through lovely riparian right down in the creek bed. And the occasional sandy stretch will often host several species of birds bathing in the shallows.
Expect to find a nice selection of warblers: Yellow, Black-throated Gray, Orange-crowned, Wilson’s, MacGillivray’s, Hermit, Townsend’s, and perhaps a Nashville. And, of course, Pacific Slope Flycatcher, Western Wood Pewee, Western Tanager, and keep an eye overhead for a Swainson’s Hawk. Vagrants pop up from time to time (I found a Tennessee Warbler a couple years ago), so don’t discount the prospect of a nice surprise.
Bring water and snacks. Facilities are limited to a porta-potty at the parking lot.
Trail Rating: Category 1, an easy walk.
Leader: Tracy Farrington. 925-788-6223

MDBA Field Trip -- Outer Point Reyes
2025-05-31 08:30 - 15:00 | Kenneth C. Patrick Visitor Center, 1 Drake Beach Rd, Inverness, CA, 94937, United States
Point Reyes is one of the premiere birding locations in Northern California, a great spot to find rarities during migration—like the Prairie Warbler pictured above (image by Beth Branthaver). MDBA tries to visit at least twice a year. On our spring trip we hope to see northbound migrants as well as resident birds in their best plumage. The exact itinerary will depend on weather, but after checking Drake’s Beach and the lagoon behind it we’ll probably visit the lighthouse area, and the ‘fish docks.’ After a lunch break (BYO) we may walk down the Avenue of Cypresses to the old RCA building.
Bring water and lunch, as this area is remote. Weather is highly changeable—bring one more warm layer than you think you’ll need, and sun protection too!
Rating: Category 2 — some walking through grass under trees, and on paved roads with some significant grade.
Elevation change: 100 ft
Leader: Matt Tarlach, mdbafieldtrips@gmail.com

Bay Area Wildlife: An Irreverent Guide
Jeff Miller

Mount Diablo Bird Alliance will meet Thursday, June 5 in the Camellia Room at the Gardens at Heather Farm, 1540 Marchbanks Drive, Walnut Creek, CA 94598.

6:30 PM Doors Open

7:30 PM Main Program: Bay Area Wildlife: An Irreverent Guide
*as a conservation organization we encourage you to bring your own mug for coffee or tea
Conservationist Jeff Miller will talk about his new book Bay Area Wildlife: An Irreverent Guide, which invites Bay Area denizens to embrace their local fauna. Bay Area Wildlife casts a spotlight on the whereabouts and personalities of the Bay Area’s furred, feathered, and fork-tongued neighbors. Meet “screaming death parrots” (aka peregrine falcons), “disco slugs dressed for a P-Funk concert” (nudibranchs), and “rototillers with fur” (badgers), among many others. Jeff’s colorful descriptions offer a compilation of each species’ natural history and fun facts—did you know beavers have vanilla-scented butts, elephant seals have the loudest recorded burps (at 130 decibels), only Usain Bolt can run faster than a roadrunner, or that pooping whales might possibly save the world? Each section also includes tips on when, where, and how to best find and observe each animal. This irreverent and quirky guide to the coolest animal neighbors in the Bay Area will have you gawking at elk, whooping with cranes, and crowning yourself a crossing guard for newts before you know it. Mount Diablo critters featured in the book include gray foxes, bobcats, long-tailed weasels, golden eagles, peregrine falcons, Alameda whipsnakes, western rattlesnakes, tarantulas, and convergent ladybugs. Jeff will discuss iconic and ecologically essential wildlife species that are returning to our region, such as beavers, steelhead trout, condors, and black bears.
Jeff Miller is an amateur naturalist, professional conservationist, and passionate advocate for wildlife. Jeff is the founder of the nonprofit Alameda Creek Alliance and has served as its executive director since 1997, working to restore steelhead trout and salmon to Alameda Creek and protect the Bay Area’s largest local watershed. He’s a senior conservation advocate with the Center for Biological Diversity, spearheading biodiversity protection campaigns throughout the Bay Area and California, preparing endangered species listing petitions, writing press releases, and doing public outreach and organizing around wildlife protection issues. Over the last quarter century, he has been involved in conservation efforts for dozens of the most iconic imperiled wildlife species in the Bay Area, the most recent being securing state protections for burrowing owls. Jeff says that loving nature is as important as fighting for it and grieving ecological destruction. People tend to care more about animals and places that they have a direct experience with, so he wrote Bay Area Wildlife: An Irreverent Guide to try to connect readers with our regional fauna and inspire them to make a pilgrimage to witness the Bay Area’s spectacular natural phenomena.

2025-07-08 10:00 - 13:30 | Pt. Pinole Regional Shoreline, 5551 Giant Highway, San Pablo, 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.

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.

7:30 PM Main Program: So Many Ways To Be a Bird
*as a conservation organization we encourage you to bring your own mug for coffee or tea
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.
