Self-guided Birding Locations
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.
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.
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.
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.
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.
July through September are the months to see the small and graceful Wilson’s and Red-necked Phalaropes. These birds are usually found on the East and West Ponds of the Sunnyvale Water Pollution Control Plant. And, if you are lucky, you may even see them spin!
