Surveying Birds at Eden Landing Ecological Reserve

The freeways might be less crowded at sunrise, but our restoration sites aren’t.

Early morning and late evening are typically the busiest times of day for bird activity. That’s why I’ve been heading out to Eden Landing Ecological Reserve (ELER) at dawn once a week since starting to work with Save The Bay’s restoration team. Save The Bay volunteers and staff have planted thousands of plants in an effort to give native plants the advantage in colonizing this newly reclaimed land. Now it’s time to take a preliminary look at how this habitat is being used—specifically, how birds are using the sites in which Save The Bay has begun work, compared with unrestored sites.

Bird surveys involve observing a certain area for a specified amount of time. Count the birds in this area, observe behavior, note interactions with habitat and other organisms, and take down some details about weather conditions. Translation: soak in the beauty of Eden for 20 un-interruptible minutes at a time. While I marvel in the artistic contrast of dark water-worn mud channels against bright dawn-lit clouds and creeping tidewater, the egrets and sandpipers read the landscape in a concentrated search for food.  With hundreds of shorebirds calling all around me plus the occasional curious jackrabbit, focusing on just the survey area can be a challenge! But my immediate reward might come in the form of catching a Song Sparrow sneaking around with a large beakful of invertebrates, a couple of gulls bullying an American Avocet at the edge of the water, or a House Finch pair pulling silky nesting material from a seeding thistle. I surveyed birds at 4 sites at ELER: 2 sites in which restoration planting is well underway, one future site now just bare ground, and one overrun with invasive plants. All of my survey sites were located in the transition zone, the ground between the highest tide line and the upland, where Save The Bay does restoration work.

There is a lot more to learn, many more questions to ask, but a look at the results of this preliminary study is exciting. I definitely notice more bird activity in the vegetated sites. Songs sparrows pop in and out of the marsh gumplant volunteers planted in the ground two years ago. White-crowned Sparrows line up along the fence bordering the restoration site. A Yellowlegs might wander along between water and vegetation looking for breakfast. Zipping above the plants, Barn Swallows and a lone Black Phoebe catch insects mid-air. In fact, I saw an average of 5-6 birds per survey in the vegetated sites but only 1.5 birds per survey in the un-vegetated site.

Bare soil, by contrast, is less hospitable for many transition zone species.  Song Sparrows, for example, need shrubs and grasses in which to build their nests, and the seeds and fruits of plants comprise a large part of their diet. The transition zone is also an important refuge for small mammals and birds during storms and the highest tides. The site I surveyed without vegetation only turned up 7 species during 6 surveys, most of them aerial foragers who flew over the site.

Species diversity appears to be greater on both of the restored sites compared to the area with mostly invasive plants and the un-vegetated area. I saw total of 11-12 different species of birds in the locations where restoration work has begun, compared with only 5-7 species in the unrestored sites.

Peaceful mornings monitoring birds are interspersed with busy volunteer workdays in my schedule at Save The Bay. As the community comes together to improve tidal marsh transition zone habitat for species like Song Sparrows, it’s exciting to be able to share with them my findings from bird surveys: Yes, your work is making a difference.

If you enjoy bird-watching and are able to identify local birds, you can contribute your findings to inform research! Visit ebird.org to learn more.

San Francisco Bay waters are becoming clearer, but that may mean threats from algae growth
San Francisco Bay is becoming clearer.
Decades of tidal action have finally washed away most of the mess created 150 years ago by Gold Rush miners who blasted apart hillsides in the Sierra Nevada. The result was millions of tons of mud, gravel and sand that made its way downriver and ended up in the bay, clouding its waters and coating the bottom with a level of silt up to 3 feet thick.
Most of the silt, scientists say, has now moved out to the ocean.

Cosco Busan’s ship’s pilot won’t get license back
Capt. John Cota, who crashed the Cosco Busan cargo ship into the Bay Bridge in 2007, causing the worst oil spill in San Francisco Bay in two decades, has lost his battle to restart his sailing career.
On Monday, U.S. District Court Judge Jeffrey White dismissed Cota’s lawsuit against the Coast Guard, rejecting his attempt to force the Coast Guard to return his mariner’s license so he can sail again.

River otter spotted in Richmond marina
Leo Rice, a 57-year-old flight attendant for Virgin America, was on his daily constitutional Monday in Richmond’s Marina Bay when he spotted an eager river otter munching a fish in the clear bay water.
“I was just out there doing a walk and this little guy popped up and I was like WHAT?!,” Rice said. “He was not very shy at all and it was like he was not even bothered I was there.”
Rice snapped about 30 photos and took a video of the otter paddling and trying to gulp down a fish. Rice said he’s been walking Marina Bay since 2009 and has never before spotted an otter.

Bay Bridge park would offer a new gateway to the East Bay shoreline
Forget about a giant Ferris wheel or gondola car ride in the emerging plan for a big new park by the Bay Bridge — a new gateway to the East Bay and its shoreline.
Those ride suggestions have been cut out, but still in the running for the park are a fishing pier, concert meadow, a zip line, rock climbing wall, tide pool viewing areas, kayak and sail board launch sites, a boardwalk, sandy beaches and picnic tables.

Plastic bag ban debate continues
Petaluma is on the verge of throwing out the use of plastic carryout bags by grocers and retailers for good.
City Manager John Brown said the City Council will have two options before them at Monday’s meeting: join the county’s plastic ban or draft legislation specific to Petaluma that outlaws plastic bags.
“There are some cities that have said they want to do it themselves, and other cities that said they want the county to handle it for them,” said Brown. “Now it’s the council’s time to decide.”

Bay Trail Vision at Work at Carquinez Shoreline
A trail project along Carquinez Strait will provide a missing link for the Bay Trail, and with it, a restored route with sensational views for people who walk, hike, bike or run.
The route runs along along an abandoned roadway set into the cliffs west of Martinez that had been closed due to erosion, rockslides and holes, cracks and crevices in the pavement.
Construction crews placed fencing at both ends of a 1.7-mile project along Carquinez Scenic Drive. When work is complete, the route will provide a trail link from Carquinez to Crockett. The trail segment will be closed for about two years for public safety, according to the East Bay Regional Park District.

Save The Bay + GGAS = Birds and Plants

Birding with Golden Gate Audubon
Birding with Golden Gate Audubon

Save The Bay hosted a planting training day for the Golden Gate Audubon (GGAS) in exchange for a birding expedition at the Emeryville cresent.

As a trade off, GGAS led a birding trip for Save The Bay.  We saw White and Brown Pelicans, Coots, Grebes (Eared and Western), Canvasback, Surf Scooter, Ruddy Ducks, Egrets, Herons, Plovers, Shovelers, Cormorants, Avocets, Stilts, Willets, Dunlin, Sandpipers, Terns, Gulls and an amazing White tailed Kite.

Save The Bay demonstrated strategic techniques for the GGAS staff in teaching volunteers to plant natives. We also role played scenarios that are helpful in guiding volunteers.

This year, GGAS will be planting 750 native wetland plants along the Martin Luther King Jr. regional shoreline, all of which were grown at Save The Bay’s native plant nursery on site.

Save The Bay and Golden Gate Audubon are working together to enhance vital bird habitat at MLK Shoreline in Oakland. Both groups are working with other partners at other sites all over the Bay.
