Thursday January 12 was officially Golden Gate Bird Alliance Day in the City of San Francisco!
It was also the official launch of our year-long traveling exhibit on A Century of Protecting Bay Area Birds.
Over 100 Golden Gate Bird Alliance members and friends gathered at the California State Building in San Francisco, where the Centennial exhibit will be on display throughout the month of January. To a background of bird song provided by Dan Dugan of the Nature Sounds Society, people greeted old friends and and viewed the 14 panels of larger-than-life bird photos and stories of GGBA’s accomplishments.
Incoming S.F. Supervisor Jeff Sheehy presented GGBA with a proclamation from the mayor’s office designating January 12 as Golden Gate Bird Alliance Day. Representatives of  State Assemblymen Tony Thurmond and Phil Ting presented a proclamation from the California Legislature honoring GGBA’s 100 years of achievements.

Audubon California Executive Director Bridget McCormack praised GGBA’s contributions to state and national birds conservation, including GGBA’s lead role in making people aware of the need to design and site wind turbines in ways that minimize deadly hazards to birds.
And GGBA Executive Director Cindy Margulis paid tribute to the countless volunteers through the past century who  built GGBA into an effective conservation voice, an inspiring leader in nature education, and a welcoming community of people who love birds and wildlife.
Thank you to the Centennial Committee members and the event volunteers who made this a successful launch!

You’re invited to visit the free exhibit during business hours throughout the month of January, in the atrium of the California State Building, 455 Golden Gate Avenue, near Civic Center. Bring a friend: It’s a great way to introduce them to birding and Audubon. Then take a selfie in front of our giant Great Blue Heron panel and share it on social media with the hashtag #ggas100! 
Later this year, the exhibit will travel to the Tilden Park Environmental Education Center in Berkeley, Oakland City Hall and the Dalziel Building, the Tides/Thoreau Center at the Presidio, and Lindsay Wildlife Experience in Walnut Creek. Click here for dates and details.

“Oh, it’s beautiful!,” says the forty-something human, awestruck by the California Scrub-Jay.
“I see it! I see it!’” says the white-haired, cane-wielding human, looking at a Green Heron at Lake Merritt.
“There goes my free time,” moans a Millennial in the back row upon being introduced to the Cornell Lab of Ornithology website.
I love teaching my Beginning Birdwatching and Advanced Beginning Birding classes for Golden Gate Bird Alliance. My students get so turned on about the littlest things — like a handful of Bushtits — that field trips just fly by. On one recent trip to Las Gallinas, a pair of Northern Harriers and two White-tailed Kites flew over the marsh just to show off for us. Okay, yes, they were hunting, but it was a treat for us to see them.

I am thankful to finally have a classroom that really darkens sufficiently to see the bird slides in my Powerpoint. The Ed Roberts Campus in Berkeley provides a central location next to BART for Golden Gate Bird Alliance to hold our classes. And field trip locations have never been a problem: Because the Bay Area has an almost unlimited array of great birding sites, I can choose different ones to highlight the birds of each season and to avoid inconveniently narrow trails. It’s much easier to work with a group if we’re on a fire road because everyone has a chance to see the bird we’re studying. I also try conscientiously to pick sites where the birds will be closer than a half mile away. A lot closer! We spend much of our field trip time by water, because, well, that’s where the birds are. East Bay Regional Parks, Las Gallinas Valley Sanitation District (otherwise known as sewer ponds), and EBMUD lands provide a wide variety of habitats.

Beginners always make me re-think things and ask thoughtful questions. Like binoculars. Just when I think I have fully listed the characteristics of good binoculars, someone comes along with their father’s World War 2 bins. They are fixed focus. That’s right, they are permanently focused at infinity, like looking for ships on the horizon. There’s no focus wheel. “Nope, can’t use these for birding…”
Then there was the pair that didn’t have a firm axis, so every time they were lowered, the distance between the eyes changed, and then had to be adjusted each time the bins were raised to hopefully spot a bird.…

This is about a living bird that has the longest bird fossil history — stretching back to the time of the dinosaurs. The Sandhill Crane is a large, strong, but awkward looking creature. With a wingspan greater than six feet, it weights around eight to nine pounds (which is heavy for a bird). Sandhill Cranes form pair bonds and begin breeding between ages two and seven years old. They mate for life spending their next two decades together.

During the winter hundreds of Sandhill Cranes gather in the California Central Valley, and thousands gather in the Rio Grande river valley of New Mexico. These photos are from Bosque del Apache, a National Wildlife Refuge dedicated to nurturing the wintering cranes with safe locations for sleeping, water, and food.

This story begins at sunset as the cranes assemble together for safety in a shallow pond. During the night, one or two cranes will stand guard, listening for footsteps in the pond from potential predators; their hard, sharp beaks minimize the actual threat of predation.

The cranes arrive in small family groups, landing much like an airplane with their equivalent of airfoil braking:

In this particular pond, conveniently for human observers located alongside a small public road, perhaps fifty to one hundred cranes will gather for the night. In prior years there were more; the National Wildlife Service (NWS) has opened additional ponds to encourage the cranes to spread out to reduce the potential for disease transmission due to overcrowding.

In the morning, the cranes get a leisurely start after sunrise. They depart in small family groups, communicating both vocally (mostly “here I am” calls) and with physical motions.

This pose is “I am ready to fly” which eventually leads to family members adopting it and then departing.

Despite large wings and strong muscles, cranes prefer to take off though a combination of running and wing flapping. On one very cold morning, shallow portions of the pond froze solid. This allows us to watch the foot work and appreciate the sharp claws that minimize slipping on the ice.

Takeoff begins with a strong downward and forward pushing flap:

Editor’s note: Here in the Bay Area, there are no Northern Cardinals perched on snow-laden holly bushes. Instead, for iconic winter holiday imagery, we have Cedar Waxwings feasting on bright red toyon berries! In this article, reprinted from Bay Nature magazine, Golden Gate Bird Alliance field trip leader Alan Kaplan explains the role of these brilliant red berries in the winter food chain.
By Alan Kaplan
Wintering birds in our area often depend on the fruits of native and exotic (ornamental) berry plants to sustain them. Three common fruit eaters are American Robin, Cedar Waxwing, and Hermit Thrush.
In the 1970s, ornithologist Stephen Bailey looked at how these birds use berries in winter and how they interact with each other. (He was a graduate student at U.C. Berkeley at the time.) He found that toyon (Heteromeles arbutifolia) was the most important source of berries for robins, thrushes and waxwings, though they also make use of other berry plants on the university’s campus, such as cotoneaster, privet, pyracantha, holly and juniper.
Low in protein and calories, berries offer limited nutritional value, especially to small birds who need to consume their body weight in food each day to survive the winter. For example, a bird would need to consume 3 ounces of (dried) toyon berries to get the same 331 calories that could be had with only 2 ounces of sunflower seeds. Nevertheless, if you’re a wild bird you take what you can get!

Bailey found that he could learn a lot about bird behavior by watching them tackle a berried bush. Each of the three species he studied — American Robin, Cedar Waxwing, and Hermit Thrush — had a different strategy of getting its fill. Each competed with the others and none could exclude the others altogether.
The large American Robin throws its weight around, dominating the other birds when defending a rich bush of berries against individual Hermit Thrushes or a small number of Cedar Waxwings. Cedar Waxwings, in turn, overwhelm the defense of robins with their large numbers, making up with flocking what they lack in fierceness.
Both the robins and waxwings prefer to perch and pluck at berries within reach, and spend about 16 minutes at a time doing that. Robins take five berries during that time, and cedar waxwings take three. A robin might eat its weight in berries in a day (about 3 ounces), filling and emptying its crop three times per hour.…
