Out at Heron’s Head Park in San Francisco on August 6, I saw my “first of season” Spotted Sandpiper.  In fact there were two Spotted Sandpipers – one with spots and the other spotless and clean-looking, both bobbing continuously as is the habit of this species.

Upon a closer look I noticed that the feathers of the spotted one appeared quite worn. This told me it was an adult bird, probably just returned from its breeding range — possibly in the Sierra or perhaps the Cascades. This bird still had most of the feathers it attained last spring in what is called its “alternate” or breeding plumage, when it has spots on its throat, breast and underparts.

The other Spotted Sandpiper looked quite different. For one thing, it had no spots, which is similar to how an adult looks in winter after it has molted into its “basic” or winter plumage. Also, this bird seemed slightly awkward compared to the other. Its legs were paler than the adult I had just seen, it had a lighter eye line, and its feathers — while looking fairly fresh — had some light edging. Taking all of these clues together, I concluded that this bird was a juvenile or “hatch-year” bird making its way for the first time to Heron’s Head Park. These two birds were the first Spotted Sandpipers I had seen in the Bay Area since early May.

Which brings me back to “first of season” (often abbreviated in birder blogs as FOS). August, while still summer for most people, is the beginning of autumn as far as birders are concerned. Late July and early August mark the time when many birds begin to disperse from their breeding grounds and move to their wintering grounds. So these two Spotted Sandpipers, one an adult and the other a juvenile, were my FOS Spotted Sandpipers.

Now is an excellent time to see some of the birds that are dispersing or migrating from their northern or interior breeding grounds. Over the next couple of months, more shorebirds, then songbirds and water birds will start returning or passing through the Bay Area on their fall migration.

Time to get out those binoculars! What first-of-season birds have you seen so far this month? Or what ones do you hope to see? …

We recently had a fascinating encounter with a kite at Pier 94 – not a White-tailed Kite, but a camera kite.

Cris Benton is a former Berkeley architecture professor who has built a second career around kite aerial photography – using cameras attached to kites to document landscapes. On August 4, we were delighted to welcome Cris and his colleague, microbiologist Wayne Lanier, to our restoration site at Pier 94.

If you’re not familiar with it,  Pier 94 is a five-acre parcel of shoreline wetlands near Hunter’s Point, owned by the Port of San Francisco. Surrounded by industrial uses such as a gravel processing facility and a rendering plant, it’s an unlikely wildlife habitat. But over the past ten years, Golden Gate Bird Alliance volunteers have planted over 500 native plants, pulled 80 cubic yards of non-native weeds, and removed 1,500 gallon bags of trash.  Pier 94 today is home to Bank Swallows, American Avocets, Killdeer, gulls, cormorants, pelicans, sandpipers and even a nesting pair of Osprey.

On August 4^th, Cris and Wayne joined us at our monthly volunteer work session. Wayne brought his field microscope – a mini-lab that fits in his orange day pack – and showed us how to test the tidal ponds for salinity and microorganisms.

Cris brought his set of eight kites – each designed for a different amount of wind – and his Canon SLR camera with a 10-22 mm zoom. Cris rigs the camera to a kite with a system recently rediscovered from 1912 — the “golden age” of kite photography, before the advent of planes, helicopters and satellites.

The camera sits in a metal cradle with insectlike legs that cushion it from occasional rough landings. It hangs from a stabilized cross that attaches to the kite line in two places, looking a bit like a spider suspended on a couple of threads. Cris controls the camera with a modified model-airplane remote: One hand holds the kite string and the other uses the remote to angle the camera and take pictures.

Kite photography is ideal for aerial views that are closer and more detailed than anything taken from a plane or helicopter.  “I own the space between 10 feet and 300 feet,” Cris says proudly. “A fixed-wing aircraft trying to photograph at 300 feet has to rush by.…

Whether it’s the Bay sparkling in the morning sun, a mountain lake in a granite bowl, or the clear sky itself, the color blue is both refreshing and soothing.

To see an azure-blue Mountain Bluebird open its wings and spread its tail as it lifts lightly from the ground is a sight not easily forgotten.  Of course, there is no such thing as a blue bird – only certain birds whose feathers reflect the light in such a way that the bird appears to be blue.

Among the blue birds in our region, only several species – the Mountain Bluebird, the Blue Grosbeak, and the Indigo Bunting — are mostly blue.  Steller’s Jays, a resident bird in much of the west, are blue-black.

Mountain Bluebirds are most apt to show up in the winter in the grasslands in the eastern part of Alameda County, while the Blue Grosbeaks are neotropical migrants who breed along brushy areas and streamsides away from the coast.  The Indigo Bunting is rare in our parts, seen only infrequently in the summer months.  Where lacking a member of its species, Indigo Buntings sometimes interbreed with a more common Lazuli Bunting.

And then there are those blue birds who combine their blue with areas of chestnut and white.  Think of the Western Bluebird, and the Lazuli Bunting, whose exquisite turquoise back and head are reminiscent of the semi-precious gemstone.  And the shaggy-crested Belted Kingfisher whose blue verges on gray in some light, and the common, aggressive Scrub Jay, its blue tempered by gray, brown and white depending on the subspecies.

Two swallows come to mind – the Barn Swallow with its blue-black back and head and the Tree Swallow with its blue-green back and head.

Of course, not all blue birds behave alike.  The jays are aggressive by nature and are raucously vocal, while the bluebirds are quiet except for almost inaudible call notes.  As they hover above a field watching for insects, they are delicacy itself.

Some species save their blue to be used in small areas as a kind of exclamation point.  Consider the bright blue touches on several of our water birds – the blue-green wing patch on the Blue-winged Teal, and the breeding Brandt’s Cormorant’s startling electric-blue throat patch. …

My first impression of Upper Tennessee Hollow was an unfinished project. The plant growth seemed low, much of it very fresh, stakes still de-marking plant lines. Then, as I walked further along the El Polin Spring, the centerpiece and focal point, I heard the distinct mcWEEdeer call of an Olive-sided Flycatcher, followed by a Red-tailed Hawk’s shrill cry, a cacophony of finch calls, Violet-green Swallows overhead, and an Ash-throated Flycatcher(!) perched on the west slope. Oh boy, oh boy, this was a place for the birds.

Situated at the southern end of MacArthur Avenue in San Francisco’s Presidio, the El Polin Spring and the Upper Tennessee Hollow have recently been restored. However, it turns
out half the growth is quite mature, and the flanking Monterey pine and redwood groves are long settled. The year-round spring and the varied habitat make it a bird magnet. The archaeological excavations (from a Spanish/Mexican settlement there in the early 1800s) and ample graphics complement nicely as an added point of interest.

The Presidio Trust went to great lengths to capture the spring as a feature, creating slightly sunken spillways across the path – which the birds use continually for bathing – and creating a series of small ponds with weirs flowing into one another through wetlands. A Great Blue Heron has adopted the uppermost pond, though a Snowy Egret shared it recently. California Towhees, Black Phoebes, American Robins, White-crowned and Song Sparrows, Bushtits, and hummingbirds (Anna’s and Allen’s) all were in abundance.

On the early June day I visited, fledgling House Finches were lined up in the sun, two Lesser Goldfinch youngsters came to the spring, and a Hairy Woodpecker brought three small, fluffy young to a small oak right by the trail. I had to say “awww!”

The upper bowl is partial grasslands, and the Lesser Goldfinches, American Goldfinches, House Finches, and several weeks ago a pair (or trio?) of Lazuli Buntings enjoyed the grasses and seeds.

In a dozen years of leading nature trips in Honduras, not once has Robert Gallardo run into another birding group in the field.

“There are just so many areas to go running around here,” he said. “Honduras could hold many groups at one time and they’d never cross paths.”

Gallardo should know. A co-founder of the Honduras Ornithological Society, he has personally added 30 species to the list of Honduran birds and is writing the definitive Field Guide to the Birds of Honduras, to be published in 2014.

Next Thursday August 16, he’ll be sharing his stories and photos of Honduran birds with Bay Area residents at Golden Gate Bird Alliance’s monthly Speaker Series in Berkeley.

The best-kept secret about Honduras, Gallardo says, is that despite years of news about political turmoil in Central America, it is actually quite safe to bird there. Plus the country has an extensive but under-utilized reserve system that doesn’t yet draw the crowds found in places like Costa Rica.

One such reserve includes the Rio Platano — an area of virgin rain forest that is accessible only by raft and is home to tapirs, Great Green Macaws, Scarlet Macaws, monkeys and jaguars.

Gallardo first came to Honduras in 1993 as a Peace Corp volunteer. He fell in love with the landscapes, flora and fauna and the opportunity to make a real difference in local avian knowledge and birding. Since then, he’s started butterfly farms and a small eco-lodge, and led numerous birding trips including two sponsored by GGBA in 2011.

His own favorite bird? The wren family. There are 18 species of wren in Honduras, and sometimes you can find five species living in the same area.

Of the thirty bird species Gallardo has added to the country’s list, three have been wrens.

In-between writing the field guide, conducting eco-tours and speaking to groups like Golden Gate Bird Alliance, he is working on finding a fourth.
