Snowy Plover at Crown Beach

Snowy Plovers are back… with some human help

By Ilana DeBare
One of our favorite shorebirds is back for the winter… and in Alameda, at least, they are finding a safer roosting site than in the past thanks to teamwork by Golden Gate Bird Alliance and the East Bay Regional Park District.
Western Snowy Plovers are tiny shorebirds (just 1.2 to 2 ounces) that winter on many Bay Area beaches. The smallest birds in the plover family, most migrate inland for summer breeding, although a small number also breed here.
There are only an estimated 2,500 Snowy Plovers on the Pacific Coast; the federal government listed the western population as threatened in 1993. One of the challenges they face is that the flat sandy beaches where they roost have been overtaken by development and human recreation. It can be almost impossible for plovers to roost on urban shorelines without being flushed by off-leash dogs or joggers.
Why are secure roosting sites important? Casual passersby often think, “What’s the big deal? If a dog chases them, they can fly up and then settle right back down.”

But roosting is in fact an essential activity for shorebirds like plovers. Their breeding cycle is intensive and exhausting: Snowy Plovers are polyamorous, and the female may mate with several males and lay up to three clutches of eggs in three different locations a single season. She leaves after the eggs hatch, and then the male takes on sole responsibility for tending  the young.
“You can imagine that’s a pretty intensive expenditure of energy by both the females and the males,” says Cindy Margulis, Executive Director of Golden Gate Bird Alliance. “They have this flurry of breeding activity, then they have to rest and begin to rebuild their energy stores during the winter. That’s where the problem with roost sites occurs.”

When you have busy beaches with scores of dogs and hundreds of pedestrians flushing birds over and over throughout the day, it’s impossible for them to rest. Some of the disturbance is unintentional: Plovers, which roost in shallow indentations in the sand, blend in so well that beachgoers often don’t notice them until they practically step on them.
This is where people can help – and in the case of the Alameda plovers, have helped.
Two years ago, GGBA members doing a shorebird survey noticed roosting plovers on Alameda’s Crown Beach.…

Coyote Hills: Birding Hotspot

Coyote Hills: Birding Hotspot

By Pamela Llewellyn
When people visit from out of town and ask, “Where’s the best place to go birding?” I always have to pause and collect my thoughts.  San Francisco Bay is one of the richest and most diverse places to bird along the California coast — one of the major foraging, resting, and over-wintering spots along the Pacific Flyway.
Coyote Hills Regional Park in Fremont is one of my all-time favorite East Bay birding locations, due to the variety of habitats supporting diverse groups of both flora and fauna.  But it also has a rich cultural history.
The East Bay’s original inhabitants were ancestors of the Ohlone Indians, hunters and gatherers whose skills enabled them to live well off the land’s natural ounty.  At that time Tule elk, California Condors, sea otters, and fish were abundant.  Some of the rich wetlands that sustained them are preserved at Coyote Hills, along with 2,000-year old Tuibun Ohlone Indian shellmound sites.
The park’s varied history also includes Mission and settler ranching and farming activities, salt production, a duck hunting club, a dairy, rock quarrying, a military NIKE missile site, and a biosonar research facility.  Coyote Hills Regional Park was dedicated to public use in 1967 and is presently comprised of nearly 978 acres of open space.
There is not a dull time of year to bird at Coyote Hills: Each season offers a unique glimpse into the life of birds.
Spring in Coyote Hills is a very busy time of year.  Upon entering the park, the road passes through grasslands and marsh where Northern Harriers (formerly known as Marsh Hawks) soar over the reeds in search of food, or do roller-coaster loops and food hand-offs mid-air air to impress a potential mate.

Marsh Wrens chatter their staccato song out in the marshes, while Bewick’s Wrens sing melodiously from branches up on the hillside.  If you park at the Visitor Center and walk up to Hoot Hollow, you might catch a glimpse of the resident Great-horned Owl family with their newly fledged young.   Or if you walk out further into the marshes you may hear the lovely Common Yellowthroats, perched in among the reeds, singing to define territory for their families.…

Lani’s Big Year: the big push

Lani’s Big Year: the big push

Note: This is the seventh in a series of occasional blog posts by GGBA member George Peyton about his other half Lani Rumbaoa’s effort to see over 600 bird species in the Lower 48 states in 2015.
By George Peyton
In planning Lani’s Big Year, it became evident that a key to reaching her goal was making the absolute maximum use of spring. During spring, birds are in bright plumage, often singing so they are more easily located, and sometimes concentrated in relatively small areas along migratory pathways such as High Island, Texas, or Magee Marsh, Ohio.
Out of this developed a solid four-week trip to ten states, from Maine to Mississippi to Minnesota, with Massachusetts, New Hampshire, Ohio, Michigan, New Jersey, Tennessee, and North Dakota thrown in — an all-out effort to hit as many key bird locations as possible before the crucial spring birding period faded into the much duller and slower Summer.
I realized that birding all-out day after day for four weeks would be totally exhausting, so I included a large Peyton Family Reunion in Mississippi, followed by a long weekend at my 55th Reunion at Princeton, both of which did wonders in giving us a breaks from the 12+ hours of birding each day.
We started on May 11, flying to Detroit and then driving down to the Toledo, Ohio, area, in order to be reasonably close to Magee Marsh, a legendary “Migrant Trap” where the “Biggest Week of Birding” was drawing thousands of birders from around the U.S. and the world. When I first went to Magee Marsh four years ago, I simply could not believe it. In my 66 years of birding, this was the most amazing place to bird in the United States that I had ever been.
Picture this: A half-mile-long five-foot-wide boardwalk going through a wooded swamp 250 yards from the shore of Lake Erie, with at any given time between 350 and 1,000+ birders on that boardwalk.

It sounds insane, and it is! Sometimes you have to be a blocking back pushing through the crowds of birders and forests of scopes and gigantic Bazooka-looking cameras on tripods — mostly Canons — pointed in every direction. Why in the world would any mentally competent birder ever endure this mass of humanity and constant traffic jam?
The answer is the amazing variety of birds, particularly warblers, often very close, often at eye level, not infrequently singing their hearts out, and for the most part totally oblivious to all of the crazy birders nearby.…

Birding South Texas with Golden Gate Bird Alliance

Birding South Texas with Golden Gate Bird Alliance

By Steve and Carol Lombardi
In April, we joined five other Golden Gate Bird Alliance members on a nine-day birding adventure to the South Texas coast and the lower Rio Grande Valley. Eddie Bartley and Noreen Weeden of NatureTrip, both longtime GGBA members, were our excellent, well-organized guides.
The South Texas coast is a top birding destination in the spring because of the migrant “fall-out” – tens of thousands of birds descending for rest and food after their long flight north over the waters of the Gulf of Mexico.
Highlights of the trip included

  • 222 species on our list. Lots of warblers and other neotropical migrants, helped in part by the migrant fall-out at South Padre Island: One of those “Over here! Over there! And over there!” mornings.
  • Thirty different spots visited, including state parks, roadside rests, beach towns, and wildlife refuges. We traversed the southeast corner of the state, starting in Corpus Christie, going south to the South Padre Island/Brownsville area, up the Rio Grande Valley as far as McAllen, and back to Corpus.
  • Nine days of good accommodations, including five very nice 3-star hotels and a bunch of very, very good meals—yes, even vegetarian!
  • Good weather (for the humans). The area can be uncomfortably hot this time of year. Instead, we had cold fronts, which kept the daytime weather temperate and cloudy and contributed to the fall-outs we witnessed.

The gulf coast is definitely a tourist destination, as is apparent from the architecture. But they also take their birding seriously. Local conservation groups have purchased woodlots and marshes in the middle of neighborhoods to protect them from development and provide habitat. Result: Great birding with on-street parking.
This spiffy natural habitat—created  within the residential area—also wins the Most Adjectives In A Plaque Award. This spiffy natural habitat—created

We spent our first day of the trip in and around Port Aransas, across the bay from Corpus Christie on Mustang Island. We were treated to great close-up views of migrating shorebirds on the beaches and neotropical migrants in the nearby woodlots. As Californians, we were pretty well bundled up against the expected bugs. So we were bemused (well, shocked, really) to see many of the local folks out birding in shorts, t-shirts, and flip-flops. We hit half a dozen well-known spots in this area and—among other lessons—grasped the difference between Laughing and Franklin’s Gulls.
After a rain delay that forced us to kill some time in a German bakery (oh, woe is us), we headed south toward Brownsville and South Padre Island, where we spent three nights.…

Time to celebrate shorebird migration!

Time to celebrate shorebird migration!

By Maureen Lahiff and Linda Carloni

Migration is always a natural wonder, whether of songbirds or Monarch butterflies or herds of caribou, but shorebird migration, following patterns from the Pleistocene, is truly an event to be noticed and treasured.

Now there’s even a special day to celebrate it – World Shorebirds Day, September 6, with global shorebird counts on the weekend of September 5-6!

First observed in 2014, World Shorebirds Day aims to raise global awareness of shorebirds and the challenges they face from loss of wetlands. It was founded by György Szimuly, also known as Szimi. He’s Hungarian, so he’s travelled to pursue his passion; he now lives in England. For more information, and some great photos and art, go to the website worldshorebirdsday.wordpress.com/.

San Francisco Bay is crucial for shorebirds

Even though more than 90 percent of San Francisco Bay’s original wetlands have been lost or seriously degraded by urban development, over 1 million shorebirds visit the Bay each year.

The Western Hemisphere Shorebird Reserve Network has designated San Francisco Bay as a Site of Hemispheric Importance – the network’s highest ranking of importance. According to the Southern Pacific Shorebird Conservation Plan (2003), the Bay Area holds higher proportions of the total wintering and migrating shorebirds on the U.S. Pacific coast than any other wetland.   For 11 species, over half of the individual shorebirds counted on the Pacific Coast in a given season are found here. (That season is most often winter or fall, sometimes both.)

According to the conservation plan, there are 13 species for which the Bay shoreline is critical: Black-bellied Plover, Snowy Plover, Semipalmated Plover, Black Oystercatcher, American Avocet, Willet, Long-billed Curlew, Marbled Godwit, Black Turnstone, Western Sandpiper, Dunlin, Short-billed Dowitcher, and Red-necked Phalarope..

What is a shorebird, anyway?

Not all birds we see on the shore are classified as shorebirds for conservation and monitoring purposes. Gulls, for instance, are not considered shorebirds. One good description of a shorebird is a bird that feeds in wetlands by probing with its bill or picking up food from the surface. Many shorebirds such as curlews nest inland. Some sandpipers like Mountain Plovers are grassland birds — “grasspipers,” as Kevin McGowan of the Cornell Lab of Ornithology calls them. Not all shorebirds are limited to winter visits: Small numbers of Black-necked Stilts, American Avocets, Black Oystercatchers and threatened Western Snowy Plovers are here year round, though they can be difficult to find.…
