Lani’s Big Year goes to South Texas

By George Peyton
South Texas is a great place to bird, particularly for a Big Year, since it has a number of bird species that are either difficult or impossible to find elsewhere in the United States, from easy-to-find birds like Green Jay or Plain Chachalaca to difficult-to-find species such as Hook-billed Kite.
As part of the Big Year being attempted by my better half Lani Rumbaoa, we spent ten full days birding South Texas in mid-February. We started by taking the Wharf Cat, a catamaran, from Rockport, with the primary goal of seeing Whooping Cranes.
The crew always includes a very knowledgeable birder — often the Captain — to point out the numerous birds seen during the four to five-hour cruise around Aransas National Wildlife Refuge. And because the Wharf Cat has an upper deck and is a very stable boat, Lani had great visibility, and with our own scope she was able to see six or seven family groups of Whooping Cranes, some quite close.
A very endangered species, Whooping Cranes rebounded from a low of just 15 individuals in the 1940s to the current population of about 600 birds, thanks to a heroic restoration effort that is still going on. The tallest bird in North America, Whooping Cranes are pure white with a dark red crescent on the face. They were absolutely magnificent to watch as they slowly stalked their prey, small crabs, in the Texas marshes.

We spent most of the next day on a guided bird tour on the King Ranch led by Jim Sinclair, very tall (6 feet 8 inches) and very slim, with an Oklahoma/Texas drawl, and an excellent bird leader. Jim spent many years in the Navy and during a long stay in San Diego saw over 400 species in San Diego County alone — obviously an avid birder.
While we unfortunately could not go to the southern part of the King Ranch where the Ferruginous Pygmy Owl is found (that area was not opening up until approximately a month after we left), Jim tailored our birding to find new species for Lani’s Big Year List. He had the patience to spend over two hours driving the short grass strips on either side of the ranch roads to finally locate Lani’s top Target Species for the day, a Sprague’s Pipit, which is very difficult to find anywhere in the U.S. …

Speak out to protect Altamont raptors

By Mike Lynes

The Altamont Pass is a problem for birds that just won’t go away. So that makes it a problem for Audubon too – a problem that will come to a head next Tuesday March 24.

While significant progress has been made in reducing bird deaths in the Altamont Pass, one company, Altamont Winds, Inc. (AWI), is trying to extend its current permits to run some of the most dangerous, old-generation turbines for another three years until 2018. If approved, the project would kill approximately 1,900 birds, including 280 to 400 raptors and at least 11 to 16 Golden Eagles, 82 to 139 Burrowing Owls, 86 to 96 American Kestrels, and 55 to 87 Red-tailed Hawks.

Not surprisingly, the proposal is opposed by Audubon, Save Mount Diablo, the Bay Chapter of the Sierra Club, the East Bay Regional Park District, the U.S. Fish & Wildlife Service, and the office of the California Attorney General. The project was initially rejected by the East County Board of Zoning Adjustments (EBZA) in February, but AWI appealed. The Alameda Board of Supervisors is scheduled to hear the issue on March 24, and seems poised to overturn the EBZA and approve the project.

AWI’s efforts to continue profiting from its old-generation turbines not only pose an unnecessarily high risk to birds, but they violate what has been Alameda County’s stated wind policy since at least 2005. At that time, the County and several wind companies settled litigation brought by five Audubon chapters – Golden Gate Bird Alliance, Santa Clara Valley Audubon, Marin Audubon, Ohlone Audubon, and Mt. Diablo Audubon—together with Californians for Renewable Energy (CaRE) and agreed to reduce bird deaths by 50 percent and expeditiously remove the most dangerous, old-generation turbines in the Altamont.

Removal of older turbines is one of the key strategies for making the Altamont Pass a productive site for renewable energy that does not unduly harm local bird populations. For decades, the old-generation turbines killed thousands of birds each year without mitigation. In the early 2000s, it became clear that to keep wind energy in the Altamont, the old turbines would need to be replaced with newer, safer turbines that were sited to minimize risk to birds, a process called “repowering.”…

The avian richness of Sonoma County

By Bruce Mast

The composite checklist of native, non-introduced birds for all nine Bay Area Counties adds up to 549 species.* A quick scan of the county checklists confirms a familiar pattern: species diversity is richest in the coastal counties.

Marin County, with its world-class vagrant traps at outer Point Reyes, leads the pack with a checklist of 481 species. San Francisco, though heavily urbanized, includes some great vagrant traps in the western part of town and lays claim to the vagrant super-magnet Farallon Islands, which puts it in respectable second place with 472 species. San Mateo and Sonoma Counties follow behind with 445 and 437 species respectively.

But birding a location with a long vagrant checklist doesn’t mean you will see many birds in the field. What if we exclude the vagrants and locally rare (i.e., less than annual) species and just focus on the regularly occurring birds? Even though Solano and Contra Costa offer access to some great Central Valley birds, the coastal counties still lead the way due to their unique habitats for gulls, alcids, rocky shorebirds, tube-noses, and diving ducks.

Among the coastal counties, Sonoma vaults into first place with 281 species, Marin and San Mateo drop to second and third place with 271 and 264 species, and San Francisco falls all the way to sixth place with just 243 species.

Sonoma County

So what’s so special about Sonoma? The short answer is the quality and diversity of habitat.

Southeastern Sonoma County includes the extensive Napa-Sonoma and Petaluma Marshes that extend well up the Petaluma River to Ellis Creek and Shollenberger Park. Ridgway’s and Black Rails are regular denizens, along with small numbers of Tundra Swans and Greater White-fronted, Snow, Ross’s, and Cackling Geese. Similar habitats in the bay-fronting counties to the south have been more heavily impacted by urbanization.

Bell’s Sparrow along Pine Flat Road in Sonoma County, by Bruce Mast

Sonoma’s interior coast range offers dry upland habitats—oak savannah, gray pines, and chaparral–that are sparse or non-existent in the other coastal counties. With multiple peaks reaching above 3,000 feet, the Mayacama Mountains are a good place to find Poorwill, Purple Martin, Canyon Wren, California Thrasher, and Bell’s Sparrow. Lewis’s Woodpecker is generally more dependable in Sonoma County than the other coastal counties.

Along the coast, Sonoma offers forests of redwoods, pines, and douglas fir that extend all the way up the north coast into Canada.…

Audubon in Sacramento

By Ilana DeBare

Guess who visited the California State Capitol on Wednesday:

One leucistic Red-tailed Hawk. One American Kestrel. One Great Horned Owl.

And dozens of Audubon members from chapters throughout the state, including Golden Gate Bird Alliance!

Diane Ross-Leech, Leslie Silver, and I joined our colleagues from other chapters in a “Birds Matter Day” lobbying blitz organized by Audubon California, the first such statewide effort by Audubon in over a decade.

As we gathered for breakfast and an orientation across the street from the white-domed Capitol building, we were greeted by a familiar face — former GGBA Executive Director Mike Lynes, who now, as Policy Director for Audubon California, treats the Capitol as his “patch.”

We also were given an insider’s view of the lobbying process by former Assemblyman Pedro Nava, who serves on the Audubon California board.

“As a legislator, when I had visits from Audubon, I paid attention,” Nava told us. “Audubon has a reputation for being responsible and understanding that compromise is not a dirty word.”

After breakfast we fanned out in teams to visit legislators and their aides. Our mission was to establish relationships with our local representatives — so we can work together with them for a healthy, clean environment for both people and birds.

Ready to lobby!

We let them know Audubon’s positions on several key issues:

Climate change. We shared the scary results of last fall’s study by National Audubon, which found that HALF of all North American bird species risk extinction over the next 80 years due to climate change. And we expressed our support for the package of climate change bills being put together by the State Senate Leadership.
Wildlife corridors. We supported AB 498 by Assemblyman Marc Levine of Marin County, which would encourage creation of habitat strips connecting wildlife populations that have been turned into isolated “islands” by freeways, development, etc.
Salton Sea. No specific bill yet — but something must be done to prevent this major stop on the Pacific Flyway from drying up.
Lead ammunition. Yes, California finally passed a ban on lead hunting ammunition — but now the gun lobby is pushing a bill, AB 395, to overturn the ban. We asked legislators to oppose this bill.

In meeting with Bay Area and coastal lawmakers, we received encouragingly warm and friendly responses. One aide (to Senator Hannah-Beth Jackson from Santa Barbara and Ventura counties) even told us she was an Audubon member!…

Domestic squabbles in Osprey land

Golden Gate Bird Alliance member Lee Aurich turned his camera lens on the pair of nesting Osprey at a construction crane in Richmond… and found some avian domestic drama. Here are his photos and story.

By Lee Aurich

The Richmond Osprey are in the process of moving back into their nest atop the Whirley Crane. As you will see below, they seem to be having some problems with “married life.”

To set the stage, the heavy winds late last year rearranged the nest atop the Whirley Crane. The couple is in the process of rebuilding and extending.

The status of their work, in this cage perhaps 60 feet up at the end of one of the Richmond piers, is recorded in this photo:
