The unanticipated can seem like a monkey wrench into the gears, and yet prove to be a great stroke of luck. This happened to our Birdathon trip last weekend at Pinnacles National Park.
We had planned an hour of riparian birding near the campgrounds till the air warmed up enough for soaring California Condors. But we abruptly cancelled the riparian walk due to the number of people flooding the campground area on this spring weekend.
Instead we scooted up to stop 2, the Bear Gulch headquarters, just in time to have a California Condor alight in a snag next to the parking lot!
This bird gave us several minutes of spectaclar close viewing before dropping down to a deer carcass, a well picked over mountain lion kill easily within view. The morning never really warmed and this was to be our only California Condor — though a condor tracker we met on the trail had a total of 10 electronic “detections” of perched, radio-tagged birds on the mountain sides.

The hike up Condor Gulch trail was wonderful, with spactucular vistas unique to this special place. We had a nice bird list too, including Peregrine Falcon, Blue-gray Gnatcatcher and Calliope Hummingbird. Special thanks to our host, condor-tracking volunteer Richard Neidhardt.
Postscript: It turns out that the mate of “our” condor followed us back to the East Bay this week. The Oakland Zoo recently started a new partnership with the National Park Service where they will treat condors that have been found with high levels of lead in their bodies. Today the zoo received its first condor patient — condor number 444, the mate of number 340, the young male in these photographs. Lead poisoning is a significant threat to condors that eat carcasses containing the residue of lead ammunition. Although California passed legislation banning lead bullets in hunting, the law won’t take effect for several years, so there remains a continuing need to test and treat condors for lead poisoning.

Rusty Scalf, who co-teaches GGBA’ Birds of the Bay Area class, led the Pinnacles field trip on April 26 as part of Birdathon 2014. But you can visit Pinnacles anytime! Spring is a lovely time to look for wildflowers there, as well as the park’s year-round population of 27 free-flying California Condors that have been reintroduced there since 2003.…

Looking at Rita Sklar’s vivid paintings of birds, you’d think she’d been wielding both binoculars and brushes since she was a child.

But it’s been less than two decades for both.

Sklar – a prize-winning Oakland painter who will be exhibiting her work at our Birdathon Awards Celebration on Sunday May 18 – received her first set of paints as a 10-year-old. She took to them with gusto. But then she abandoned painting in junior high and didn’t pick it up again until around 2000, when she took a watercolor class in Spain.

That was soon after she first started paying attention to the birds all around us.

“I’m embarrassed to say I didn’t even notice birds for most of my life,” Sklar said. “Then I was walking around Lake Merritt for exercise and I noticed some ducks, and saw that some looked different from the other ducks, and that led me to start walking around with a (bird) book. I was getting less exercise, but I was getting more fascinated.”

Sklar joined Golden Gate Bird Alliance and started going on field trips with volunteer leaders like Bob Lewis and Rusty Scalf. She began learning about the environmental threats to bird populations.

That launched her on a series of paintings of birds in decline – at-risk species such as Nuttall’s Woodpecker, California Thrasher, Tri-colored Blackbird, and Surf Scoter.

Some of her works are traditional watercolors. But others are experimental or mixed media. Her Surf Scoter painting (shown next to her, above)  is a collage that incorporates fragments of pages from a report about the Cosco Busan oil spill.

“I like trying different things,” Sklar said, taking a break in her cozy Dimond district studio, where the walls are covered with her prints and paintings. “My quail painting is on rice paper, and my Canvasback is on Yupo, which is a kind of plastic that doesn’t absorb the paint.”

Sklar doesn’t typically paint in the field. She works from photographs – either her own or more detailed close-ups by local bird photographers like Bob Lewis. In recent years, she has moved towards combining realistic bird images with abstract backgrounds as in her painting of Black-necked Stilts in flight.

“I did the birds first, then I covered them with a frisket (protective coating) to protect them,” she recounted of the stilt painting.…

The 9.7-acre nesting area for the endangered California Least Terns at Alameda Point received a new layer of sand this year. Sixty dump truck loads of sand were delivered to the site on the old Navy airfield in March, paid for by the U.S. Fish & Wildlife Service (USFWS).

After the sand was moved into place, USFWS and volunteers set up a numbered cinderblock grid system used for recording behavior and also distributed chick shelters and oyster shells for the chicks to use as protection from the elements and predators.

On Sunday April 13, a dozen volunteers showed up for the last work party prior to nesting. The task of the day was distributing oyster shells around the site, which provides a nominal amount of sun protection for chicks and, in theory, helps make it more difficult for avian predators like Red-tailed Hawks and Peregrine Falcons to spot the chicks amongst all the white shells.

From now until the end of the nesting season in mid-August, volunteers will be participating in another program called the Tern Watch Program. Participants monitor behavior and watch for predators from their vehicles outside the nesting area.

Throughout the nesting season, a USFWS biologist makes periodic walks through the site and places numbered plaster markers next to nests so that the number of eggs and success rate can be accurately recorded. If there are three eggs in a nest one week, for example, and one egg the next week with no chicks, it’s an indication that predators have grabbed the eggs.

Each year following the end of the nesting season in August, volunteers at monthly work parties gather up the oyster shells, the wooden A-frames, drain tiles, grid markers, and the hundreds of numbered markers used to identify nests. Clearing the site makes it easier to remove weeds and grade the sand, which can erode during rains. The volunteers pull weeds from inside and around the perimeter of the fenced-in site. The volunteer program during the non-nesting season is organized by the Golden Gate Bird Alliance’s Friends of the Alameda Wildlife Refuge committee, in conjunction with the USFWS biologist in charge of the Alameda Point tern colony.

The effort to protect the Least Terns was begun by the Navy when nesting activities were first noticed in the 1980s.…

This year, we’re celebrating the 150th anniversary of the Yosemite Grant and California State Parks with much festivity.  But  Yosemite Valley and the Mariposa Grove were granted to the State of California in 1864 for “public use, resort, and recreation.”

What was the first area in the U.S. set aside specifically for wildlife? Oakland’s Lake Merritt!

In 1870, the Lake Merritt Wild Duck Refuge was created by the California State Legislature.

Today Lake Merritt looks much different than it did 150 years ago.  The wetlands that once surrounded it are gone. But it is still a wintering spot for thousands of migratory waterfowl and a year-round home to a great variety of resident birds.

Every other Saturday morning from March through early June, GGBA provides docents at Lake Merritt in partnership with S.F. Nature Education. We set up a spotting scope and information table near the artificial islands, along the path just east of the Rotary Nature Center. I love serving as a docent there. Ducks come in close to the walkway and offer us good looks and plenty of chances to see them interacting.  Gulls drop mussels on the path to crack their shells.  Black-crowned Night Herons sit motionless in the trees.  American White Pelicans sail by; in spring, we see the “breeding bumps” on their bills.

The Double-Crested Cormorants are one of the highlights for me.  Forty to fifty pairs nest in trees on the islands.  This time of year, we can actually see their double crests of feathers, and the bare throat skin near their bills — their gular patches — are bright orange-yellow.  We saw a male displaying on a nest on March 8th, and several birds carrying sticks to refurbish nests for the current season on March 8th and 23rd.  The males and females look alike, and both contribute sticks to the nest building.

At the beginning of March, a lot of the wintering ducks were still there: many scaup (mostly Lesser Scaup), about a half dozen Canvasbacks, some Bufflehead, and Pie-billed Grebes.  On March 23, the Canvasbacks were gone and there were fewer scaup.…

On the first day of spring, twenty third-grade students from Oakland Unified School District’s Korematsu Discovery Academy bravely head into the outdoors. They are accompanied by their teacher, several parents, one grandparent, volunteers, and their leaders — Anthony DeCicco and Marissa Ortega-Welch, who work with 700 low-income schoolchildren each year in Golden Gate Bird Alliance’s award-winning Eco-Education program.

Their destination is the Arroyo Viejo Creek, just outside the Oakland Zoo in Knowland Park. Seven years ago this portion of the creek was restored to provide better habitat for wildlife and increase human access. Many institutions collaborated to make it happen, including the California Coastal Conservancy, City of Oakland, Oakland Zoo and Urban Creeks Council. The restoration project also resulted in the perfect outdoor classroom.

This is the students’ second Eco-Ed field trip. In the fall, they visited Arrowhead Marsh where they went birding and planted wetland plants to support endangered Clapper Rails. Today they are here to explore the creek habitat – to see what lives here and understand how the creek is connected to the Bay.

The class splits into two groups. Anthony takes one group over to an open area that needs more native plants. The students gather around as he orients them. Pointing to the creek, he asks “What is the name for this?”

One excited boy yells out “A sewer!”

Anthony looks surprised but waits for more answers.

Unfortunately, the boy’s answer is not as silly as it sounds. The day before, volunteers from Friends of Sausal Creek discovered a sewage spill in that nearby creek. City staff recommended that people stay out of Sausal Creek until further notice.

A lot of work goes into making sure that local creeks are safe places for an outdoor classroom. Seeing the kids crawling over the banks and touching the water, I remind myself not to take water quality for granted.

Anthony keeps the kids focused and engaged with lots of call and response.

“A fancy word for a creek is ‘riparian.’ Can you say it?”

The children chant back, “Riparian!”

Anthony explains today’s project: planting sagebrush. He asks, “How will this plant be helpful to animals? Like a rabbit or a bird?”

“They can hide,” one student says.

“Correct,” says Anthony. “The plants will provide shelter for animals to hide from predators.”…
