We’re delighted to share the news that San Francisco Mayor Ed Lee has signed an America’s Cup settlement agreement that will provide benefits to Bay Area bird populations, both during the world-famous yachting event and in years to come.

Golden Gate Bird Alliance was among several community groups that appealed the environmental impact report for the 2013 America’s Cup.

We were concerned about impacts to birds, especially birds on the open water of the Bay and the threatened Snowy Plovers at Crissy Field.

Among many other provisions, this settlement will provide $150,000 for a three-year study of the impacts of disturbances to birds on the Bay, including disturbances from boating activities.

The city also agreed to abandon plans for a floating Jumbotron video screen in the waters of Aquatic Park lagoon, which is good news for swimmers and recreational users as well as wildlife in the area.

Meanwhile, in parallel talks, event organizers have promised to cordon off and provide monitors around the Snowy Plover area at Crissy Field, to prevent America’s Cup spectators from disturbing those at-risk birds. Similar steps are being taken at other ecologically sensitive sites.

The Bay Area is a site of international significance for shorebirds and contains many Audubon Important Bird Areas, including the open waters.  Particularly in winter, the Bay draws large populations of feeding and resting birds such as Double-crested Cormorants, Greater and Lesser Scaup, Buffleheads, Surf Scoters, Western Gulls and several kinds of grebes.

These “rafting” birds rely on the Bay to nourish and reenergize them for future migrations and breeding. Yet there’s much less Bay today than there used to be: Ninety percent of its wetlands and forty percent of its surface water have been lost to landfill and development since 1850. The remaining open water is heavily used by boats, which can flush rafting birds from as far away as 100 to 500 meters.

The environmental impact report for the America’s Cup estimated that race events will draw about 1,800 spectator boats carrying 18,000 passengers on the open waters of the Bay. Even more spectators will line the Bay at various viewing sites.

Now, as part of the settlement agreement, the U.S. Geological Survey will conduct studies before, during and after the America’s Cup to determine how boating activity affects bird populations on the Bay. These surveys will provide baseline data to guide future special events involving the Bay, and will help us protect birds from both daily marine traffic and unforeseen disasters like the Cosco Busan oil spill.…

No matter what your normal birding pattern is, sooner or later you’ll probably find yourself chasing off in hopes of finding a particular species.  Often it’s a potential addition to your life list, which might generate the need (or “opportunity,” as birders usually put it) to visit a new part of the country. Arizona, say, or Texas or Alaska.

Other times it’s an individual bird that gets your blood pumping, maybe one that shows up way out of its normal range.  Could be a bird never before found in your favorite birding patch, in your home county, or even in your part of the world. You might want to chase it, or a friend might suggest a chase.  Either way, one is likely to ask, Do you think we’ll find it? … and then hope for an encouraging reply.

California birders got a jolt to their chasing impulse recently when they learned that PRBO Conservation Science biologist Peter Warzybok had detected a Northern Gannet flying near Southeast Farallon Island early on the morning of April 25.  Within hours, links were published to distant flight shots, and before nightfall Sophie Webb’s spectacular full-frame photos made the rounds.

A Northern Gannet!  A beautiful member of the Sulidae family that breeds in cliffside colonies along the north Atlantic coastlines of North America and Europe.  But there are no known records anywhere in the Pacific Ocean.  So how did it get here?  The next day, Pacific Seabird Group researchers reported that a Northern Gannet had been seen in the northeastern Chukchi Sea in 2010, when the Northwest Passage was ice-free, and seen again a few days later further west near Barrow, Alaska.  Perhaps the question had been answered.

Chasers began to wonder: Will it stay around? The answer came on May 1, when the bird was seen again.  Next chaser question: Is there a chance of seeing it?  The answer was another yes: Dedicated pelagic birding trips to the Farallons were scheduled for July 15, and for August 5 and 19.

But that’s a long time off!  Can’t we try sooner? cried the chasers.  A third “yes,”  since whale-watching boats visit the Farallons on many summer weekends.

In mid-June, Riverside birder Curtis Marantz began to investigate the possibilities. …

It’s this way every year. June’s sunny days end with the arrival of July and the return of the coastal fog. In this summer-dry climate, any moisture should be welcome. I try and appreciate the gray mists enveloping my hill and how the fog-drip dampens the soil and puts a wet sheen on the foliage.  When fog drip was measured under the trees along the ridgeline in Tilden Park, an astounding 10 inches was collected – more than a third of our annual precipitation.

What intensifies the gloom for me is the decline of birdsong.  It’s tempting to blame the lack of sunshine.  But I know with breeding season mostly over, there is less to sing about – no territories to vocally defend, no females to attract.  The Spotted Towhees are still singing – not a surprise for a species that typically has more than one brood each spring.  Sometimes I hear a stanza or two from a distant Black-headed Grosbeak. Or a robin, undaunted by the gloom or the lateness of the season, sings its cheery song.  The irrepressible Bewick’s Wren periodically bursts forth, and out over the open hillside I can hear the plaintive call of a Red-tailed Hawk who can’t quite accept it is on its own now.

Look at the local bird listserve, East Bay Birding Sightings, and you will see that there is now less to report.  Only Bob Richmond — reporting regularly from the Hayward Shoreline and knowing the value of place closely observed — has heartening news that shorebirds are once again on the move.

During the brief period of clearing skies, I went out onto the open hillside headed for the pond below Lawrence Hall of Science where you can stretch out under the branches of the big-leafed maple.  I find that a sky viewed through green leaves looks especially blue and deep.  And what better way to watch for swallows and swifts or the antics of passing ravens than while lying on your back?

Whether upright or supine, I’m always on the lookout for swifts.  And when I’m not finding them, I’m reading about them.  Early on, I learned that they are not related to swallows as I had assumed, but to hummingbirds.  They are hardly sippers of nectars or able to suspend themselves midair, but like hummingbirds, swifts are masters of flight.…

(Note: Jack will present slides and describe his expedition to Papua New Guinea on July 19 at our monthly Speaker Series in San Francisco.)

In fall of 2011, I led an expedition to some of the most remote islands off the southeastern tip of New Guinea.  The primary purpose of the expedition: To survey the birds on these islands, and collect samples that could be used to study the pathogens that they carry.

Milne Bay Province, where we worked, has over 600 islands.  Each represents an independent evolutionary experiment,  where birds and other critters arrive by wind and ocean current.  Some survive and some don’t.  Once isolated, they begin to evolve with the other species that also survived and form their own unique island ecosystem.  (And by the way, each one is quite beautiful and photogenic too.)

Our first task was to survey the birds on as many different island groups as we could visit in a two month period.  We birdwatched, recorded calls and set up nets to catch birds.  We surveyed local villagers and visited their hunting grounds.  We tried to take the pulse and assess the health of the bird populations there.

Our second task was to collect samples for studying bird diseases.  Birds can carry a variety of tiny “bugs,” including blood-borne malaria species, viruses and other parasites.  We mostly sampled blood and took oral and fecal swabs, and brought these back to be screened by virus and malaria experts at U.C. San Francisco and San Francisco State University.  By studying many small islands, each with different birds and different diseases, we hope to understand how the diseases are transported from island to island and how they affect avian health.

But mostly, it was a great adventure.  To get to these places, we traveled with an amazing French couple who built their own sailboat, we visited traditional island villages where people still build and sail outrigger sailing canoes, we ate local food, and we saw and handled most of the species that are resident breeders on the islands.

With the school year ending, it was time for me to write up the annual summary of Golden Gate Bird Alliance’s Eco-Education Program, in which we lead kids and families from twelve low-income elementary schools in discovering nature and wildlife.

The past year included 50 weekday field trips to local wetland and riparian habitats, over ten family trips to Muir Beach and Alcatraz, and 30 expeditions surveying living organisms in schoolyards. As I catalogued the outcomes, I found myself stumbling over the phrase “notable discoveries.”

“Notable to whom?” I wondered.  To the eco-adults reading the report, or to our urban students out in the field for the first and perhaps only time all year?

If the latter, then “notable discoveries” would surely include the burnt-orange breast of an American Robin… the mohawk atop a Stellar’s Jay… a jackpot of scurrying shorecrabs as kids turned over a mudflat rock…  a two-inch Jerusalem cricket (aka Niña de la Tierra) crawling across the path… or a newly hatched Western Gull.

And what about my own personal epiphanies for the year, the moments when I yelled in excitement either to the kids or to myself?

Those included:

• Seed shrimp swimming in the vernal pools near the abandoned parking lot of Merritt College in Oakland.

• Bright orange scuds (freshwater amphipods) at the headwaters of Islais Creek in Glen Canyon.

• 2×2 inch, paper-thin flatworms undulating along the underside of a rock along the Point Pinole Shoreline.

• A lone Wilson’s Phalarope that landed near me in the waters at Pier 94 and began to forage so elegantly. (YES!)

Other thrilling moments shared by both adults and students were when a burrowing owl and an American crow engaged in an aerial battle above Paul Revere Elementary in Bernal Heights…  when a damselfly along Islais Creek emerged from its nymph-shaped exoskeleton…  and when we collected a mystery species of gunnel fish from under a rock along the tides at Pier 94 and mistakenly screamed “eel!” as we watched its body wriggle in our container.

Then what about the time on an Alcatraz family trip when I was passionately proclaiming to a participating father the fascinating traits of a Brandt’s Cormorant – its streamlined swim-friendly body, its ability to dive 100 feet when fishing, its bright blue throat for courtship display?
