Waterfowl and gulls are the main menu here in winter and you will find many! Located in Campbell, this park includes six percolation ponds to explore. It is flat, excellent for walking (as well as for bikes and strollers), and it is partially accessible for people with mobility issues.
Pearson-Arastradero Preserve (Spring)
Pearson-Arastradero Preserve is located in Palo Alto and is a great place to go birding if you live in Mountain View, Los Altos, Palo Alto, or San Mateo. The park features a range of habitats from grasslands to oak woodland, and a small lake, all of which are home to a wide variety of birds throughout the year. In the spring, many birds arrive from the tropics and make this their home for a few months when they build their nests and raise their young before heading back south in the fall.
Alum Rock Park (Summer): Creekside Birding
Penitencia Creek Trail in east San José is a beautiful, shaded creek side trail with easy level walking where wildlife and birds abound. While it can be crowded after 10 a.m. on weekends, early mornings offer solitude and silence and increase the chance for wildlife and bird encounters. Deer (and their fawns) are especially common, and bobcats, snakes, and other creatures are sometimes seen. The creek hosts numerous Steelhead Trout, and in the past may have supported Coho Salmon.
Palo Alto Flood Control Basin (Spring/Summer): A Noisy California Gull Colony
If you are not sure if you are a larophobe or a larophile then come along the Adobe Creek Loop Trail between the Palo Alto Flood Control Basin and Charleston Slough in Mountain View and watch the antics of the California Gulls in their colony. We find these noisy birds so fun and hope you do too.
Parkway Lakes and the Coyote Creek Trail in South San Jose (Spring/Summer)
Lined with tule, cattails, willows, and cottonwoods, Parkway Lakes is a part of the Coyote Creek Parkway located in South County. You will travel south along the Coyote Creek riparian corridor looking and listening for breeding songbirds, water birds, and raptors.
Alviso Marina and Salt Pond A12 (Winter)
This Alviso park can be good as a quick stop or a day-long adventure, with views of all different kinds of waterfowl, marsh dwellers and shorebirds. Walk along the boardwalks to listen to the noisy song birds and rails, stand at the boat dock to scan the slough for grebes and other waterfowl, or head out to the salt pond for mesmerizing murmurations of shorebirds and an impressive number of ducks.
Sunnyvale Water Pollution Control Plant (Fall/Winter): Ducks for Days
You wouldn’t think that sewage treatment would be a travel-worthy destination, but Sunnyvale Water Pollution Control Plant’s large variety of waterfowl and passerines is well worth a trip. Whether you’re looking for a 100-yard stroll from the car or a 4-mile hike, this spot provides excellent views of a large variety of bird species, all in a beautiful bay-front environment.
Coyote Valley (Late Winter/Early Spring): Love & Raptors in the Air
The agricultural fields of the Coyote Valley floor in South San Jose/Morgan Hill are excellent birding for raptors and grassland specialties. A popular stop is Laguna Ave, where with luck you can watch courting Red-tailed Hawks, Golden Eagles, Peregrine Falcons, and more! This trip is best done by car or by bike as it involves scanning long sections of fields along roads.
Pond A4 (Winter/Early Spring): A Wintertime South Bay Birding Sampler
Walk or bike around Pond A4 in Sunnyvale for a broad birding sample of southern San Francisco Bay in winter. Diving ducks blanket the pond, terns and pelicans fly overhead, marsh birds lurk in the surrounding channels, raptors perch on utility towers, and—as a reminder of the human footprint on the landscape—crows and blackbirds scavenge around the adjacent landfill.
Martial Cottle Park (Winter): The Valley of Heart's Delight
Enjoy your visit to this vintage farm in the middle of suburban sprawl in South San Jose, a throw-back to the days when Santa Clara Valley was known as “The Valley of the Heart’s Delight” long before it became known as “Silicon Valley”.
Palo Alto Baylands (Winter): Charleston Slough and Adobe Creek
Watching shorebirds and water birds up close is fun at Charleston Slough and Adobe Creek. On a short or long walk you can take the time to study their behaviors and laugh at their antics: coots swim-chase each other, egrets dash after one another with plumes flying, dabbling ducks tip over with their tail feathers in the air…
San Tomás Aquino Creek Trail (Winter): Birds, 49ers, and Great America
When I worked in the City of Santa Clara, I would take lunchtime bird walks along the portion of San Tomás Aquino Creek Trail that runs between US-101, Great American and Levi’s Stadium. Now I walk the trail to see the wintering Wilson’s Snipes and a nice variety of birds. This unglamorous trail offers flat walking, glimpses of nature, and some fun birds amid the office parks and neighborhoods, and often yields over 30 species in a 1-mile outing.
Calero Creek Trail (Fall/Winter)
Looking for an easy, flat walk that encompasses a variety of birding habitats? The Calero Creek Trail at the end of San Jose’s Almaden Valley encompasses an old orchard, riparian areas, chaparral hillside and suburban plantings that attract a wide variety of smaller perching birds and raptors.
Palo Alto Baylands (Winter): Marsh Birds and Wintering Waterfowl on the San Francisquito Creek Trail
Wondering how many Green-winged Teal and Northern Pintail can pack themselves into a small area? Pining for a glimpse of a rare Swamp Sparrow? Read on to start planning your winter trip to the Palo Alto Baylands via the San Francisquito Creek Trail!
Pond A16 (Summer): Terns and Black Skimmers
Summer is a fun time to visit Pond A16 at Don Edwards San Francisco Bay National Wildlife Refuge in Alviso. Noisy and active terns and skimmers have arrived to nest on the man-made islands in the salt pond. Come back often to see the birds in different breeding stages, from courtship to nesting to feeding their young.
Ogier Ponds (Winter): Birding by Bike or Walk-in
Ogier Ponds is a quiet, birdy, freshwater haven located in Morgan Hill along the Coyote Creek Trail. It is the perfect spot to visit during fall and winter to look for wintering waterfowl, gulls, and sparrows.
Los Capitancillos Ponds (Winter): Going on a Snipe Hunt
Wilson’s Snipe really do exist and Los Capitancillos Ponds in San José is my favorite place to hunt for them. Besides finding the elusive snipe, visit these ponds in the winter for ducks, geese, and gulls. The wide gravel travel is uncrowded making it easy to social distance.
Pearson-Arastradero Preserve (Fall/Winter)
Pearson-Arastradero Preserve is an open space preserve on the foothills of the Santa Cruz Mountains. The preserve is located in Palo Alto and is a great place to go birding if you live in Mountain View, Los Altos, Palo Alto, or San Mateo.
Pond A2E and Crittenden Marsh (Summer): Totally Terns and Snowy Plovers Too
Summer is the time to visit Salt Pond A2E in Mountain View. You will have an opportunity to spot up to 6 species of terns plus the Snowy Plovers that are “next door” in Crittenden Marsh (Stevens Creek Nature Study Area). While the parking lot can be crowded at times on the weekends, once you are out on the trails, the crowds disperse.
Los Capitancillos Ponds (Spring/Summer): Swifts and Swallows
During the spring and summer months, swifts and swallows decorate these ponds, which are located near Almaden Lake in San José. It is a great location to bird on the weekends because it is relatively quiet and uncrowded compared with better known parks nearby.
