Happy Solstice

Monarch Butterfly, Horicon Marsh, WI

Those of us in the northern hemisphere are entering into summer solstice this week, celebrating the longest day of the year and the beginning of summer. The word solstice derives from the Latin for sun (sol) and to stand still (sistere).

 

Here are a few North American summer moments, when the power of the sun (and the camera) slowed the natural world down to a perfect stand-still.

It’s a quiet moment when dragonflies cruise by–nothing says summer days like a dragonfly.

Insects and wildflowers grace us with color and vibrance as they busily gather sustenance during these longest of days.

And is there a more remarkable insect than the butterfly? I don’t think so.

 

The miracle of life in four distinct stages. They start out the warm season as an egg, hatch into a tiny caterpillar, then forage their way across the host plant, a legacy from their mother.

 

As they continue to eat, they grow into plump caterpillars until they sense the time for pupation, and form their own protective chrysalis. Then one day they stretch out of the chrysalis, unfurl wings, and fly off.

Another summer gift for us to behold: birds fledging from their nests, launching into their first flights.

Summer is a time for singing, and no birds enchant us more with melodious sweetness than the songbirds.

Rivers and ponds, forests and prairies, suburbs, cities and countrysides all come alive in summer.

We humans are cradled by the sun, presented with a whirlwind of nature during these long and productive days. We, too, sing and flutter, grow and frolic.

Lovable Lizards

Land Iguana, Isabela Isl., Galapagos

There are over 6,000 species of lizards on our planet, residing on all continents except Antarctica.  Here are some basic facts and photos of a few of my favorites.

 

One thing I love about lizards is their adaptability. Depending on the severity of danger, they can sacrifice their tail and grow a new one, change colors, and vanish in an instant.

Green Iguana, Costa Rica

Another thing I love is their solar power. Lizards are ectotherms, they require heat sources outside their body to function. Also known as cold-blooded (not technically accurate), lizards regulate their body temperature according to the sun.

 

Once in awhile I will find a lizard when the sun has been absent, like at dawn on a foggy day, and they are frozen in place. Immobile. I like this about lizards, too — their vulnerability. Of course, that’s not their favorite thing.

 

There are many remarkable features about lizards, read more here:

Lizard Wikipedia

 

Green Anole, Texas

 

Basilisk Lizard, Belize, Central America

With six thousand lizard species, there are thousands of variations. I have watched lizards run across water, eat algae under water, flare out their neck to twice its size, and hang upside down for days.

 

Some lizards change colors to attract mates, some change colors to escape detection (camouflage), and others are bright their whole life.

I live in a hot, dry climate in California. In the spring and summer we have three regular lizard species, each is a home-time favorite and much revered.

Western Fence Lizard, California

The western fence lizard is the most prevalent, we see them every day from May through October. The male does push-ups and displays a brilliant blue belly during breeding season.

Plus, this lizard has an astonishing feature. They have a protein in their blood that kills the bacterium in the tick that causes Lyme’s Disease.

 

Ticks often feed on lizards’ blood, including the deer tick that carries Lyme’s Disease. When the deer tick feeds on the western fence lizard, the bacterium is killed. My chances of getting Lyme’s Disease are considerably less because of this  lizard.

 

We also have the alligator lizard, named for their resemblance to alligators. They are skittish and infrequent, but when they appear, it is a highlight of the day.

Northern Alligator Lizard, California

Our third reptile is the western skink. They are almost always hidden, their predator list is long. I’ve learned to recognize their sound when they rustle beneath leaves; so if I wait nearby, I sometimes see them.

 

Western skink, Calif.

 

Some lizards, like the skink, move like a snake. They have short legs and wiggle and slither. But most lizards are quadrupedal and move with an alternating gait. Another thing I love about lizards…watching them walk or run, a kind of reptilian sashay that says “attitude” to me.

Nile Monitor, Botswana

 

The marine iguana, the only underwater lizard in the world, lives on the Galapagos Islands. I’ve been snorkeling when they entered the water–that’s a strange thing, to be snorkeling with a large lizard. A true thrill. They sneeze out the sea salt when they return to land.

Marine Iguana, Galapagos

Lizards bask in the sun, leap through the air, let go of their tail if it’s in the jaws of a predator, and effortlessly change colors. I wouldn’t mind having all of these features, but since I cannot, I’m happy to watch…maybe I’ll learn something.

Spring in the Sierras

Sierras overlook, California

Every season  in the Sierra Nevada Mountains is full of wonder and beauty, and right now the glories of spring are everywhere.

 

This mountain range reaches north-south, spanning 400 miles (640 km) on the eastern side of California. See map below. The Giant Sequoias, the largest trees in the world; Mt. Whitney, the highest peak in the contiguous U.S.; and Yosemite National Park, are a few remarkable features of the Sierra Nevadas.

 

Two weekends ago we visited the northern section of the Sierras, near Lake Tahoe and Gold Country.

In the upper alpine elevations there was reportedly still snow on the ground. Lower, in the montane forests where these photos were taken, the last snow fell two months ago and is gone now…and the woodlands are waking up.

Ponderosa Pine

The rivers and waterfalls boisterously cascaded with frigid, clear, mountain water — snow melt from the peaks. Most of California’s water supply depends on this snow melt, so it’s always great to see the spring waters running strong.

 

We hiked through mixed conifer forests where redwood, oak, pine, and fir trees towered overhead. Bigleaf maple trees had begun their seed production.

 

The understory was coming alive with wild dogwoods in different stages of leafing out, opening their tender white flowers, technically leaves. The yellow button flower in the center attracts insects, for pollination.

On the forest floor wildflowers were bursting through the needle duff. Wild trillium were a special find, and clumps of bleeding hearts, abundant. The gooseberries, a type of currant, will be a tasty treat for forest mammals and birds.

Caterpillars, birds and reptiles were emerging, vibrating with life. They have much to do to prepare for the new season.

Historic San Francisco Murals

Coit Tower, California by Maxine Albro

There are Depression-Era murals decorating many spots throughout San Francisco and the Bay Area, here are photos and information outlining the four major displays.

 

Funded in the 1930s by the U.S. Government under President Roosevelt’s New Deal programs, these murals employed thousands of artists during the Great Depression.

 

Murals were featured nationwide, under numerous programs, between 1933 and 1943. The Works Progress Administration (WPA) and Public Works of Art Project (PWAP) and Federal Art Project (FAP) were a few of the New Deal art programs.

Coit Tower

The four major murals in San Francisco are open to the public, and free: Coit Tower, Rincon Center, Maritime Museum, and Beach Chalet.

 

A fascinating and informative element of the murals is the history. Most depict everyday life in the 1930s and 1940s, highlighting topics of the times: economy, politics, lifestyle, daily activity, and culture, to name a few.

 

Rincon Center, The Golden Gate Bridge by Anton Refregier

There were numerous artists involved in each mural. One major artist was awarded the project, created the design, and oversaw it; and several co-artists contributed.

 

Most artists in these projects were unknown, though a few later came into popularity like Mark Rothko and Jackson Pollock.

 

In San Francisco’s Coit Tower site (1934), 26 artists and 19 artist-assistants were employed; featuring 27 murals covering 3,691 square feet (343 sq. m). Many of the artists for this site were students of Diego Rivera.

The other three mural sites had fewer lead artists. Rincon Center (1941) was led by Anton Refregier; Maritime Museum (then called Aquatic Park Bathhouse) (1938), artists Hilaire Hiler and Sargent Johnson; Beach Chalet (1936), artist Lucien Labaudt.

 

While most projects were murals, there were also tile mosaics, bas relief friezes, wood carvings, sculptures, and more. Large in scope, they occupy wall space from floor to ceiling, with extensive lengths of entire walls.

The overall theme was “American scenes” and enabled Americans of all social classes to view original art…then and now.

 

Mural artists used three different painting techniques: fresco (painting onto wet plaster); egg tempera (combining egg yolk with color pigment); and oil on canvas.

Beach Chalet, Baker Beach by Lucien Labaudt

Did the artists make good money? I’ve read many different accounts on payment. With several programs and thousands of artists, numbers vary. My understanding is that they made enough to stay fed and clothed, and working.

 

In addition to these four featured venues, there are numerous other murals in San Francisco and throughout the Bay Area.

 

Diego Rivera’s “Pan American Unity” mural (1940) at SF City College, for example, is considered one of the most important works of public art in San Francisco, and will be featured in 2020 at the SF Museum of Modern Art. Diego Rivera Mural Project

 

Also in San Francisco: Mission High School, George Washington High School, Presidio Chapel, SF Art Institute, and many other schools and locales.

Here are Before and After photos from the Maritime Museum.

This bold and colorful public art has often been controversial, sometimes at the time of the unveiling, and in later years, too. The murals are good for raising awareness and expressing opinions.

 

After over 80 years on display, restoration has become crucial. Graffiti, aging, seismic damage, and leaking roofs have taken their toll. Fortunately, communities and organizations have recognized the historical value, and funding and talented artists have been engaged.

 

There’s magic in standing in front of these paintings that tower over us, the walls that came to life eight decades ago, embracing everyday life…then and now.

The Berry-Searching Cedar Waxwing

Cedar Waxwing in Madrone Tree, Calif.

Here’s a songbird we have in abundance in the U.S., and they are personally one of my favorite American birds. Always in search of berries, the cedar waxwing is often found flying in flocks.

 

They live and breed in North America, are also found in Central America and parts of South America.   See map below.

 

One of North America’s most stunning native birds, they have a sleek black eye mask, bright yellow tail tip, tidy crest, and a lemony belly. To add to their elegance, the feathers are silky-looking in gentle shades of tan and gray. They are named for the red tips that adults have on some feathers–look like they’re dipped in red wax.

 

Cedar Waxwing flock over San Francisco Bay

A medium-sized bird, with a diet of berries and insects, they can be found in gardens, orchards, suburbs, cities, towns, and rural countrysides…wherever there are berries.

 

Many people who are relatively familiar with common songbirds, have never heard of the cedar waxwing. That is probably because this bird does not visit feeders, and they are often quiet.

Cedar Waxwing flock

I have been enamored of cedar waxwings for over two decades, and I still stop in my tracks when I hear them overhead, look for the flock. Parking lots, town centers, berry-lined highways.

 

I like to point this bird out to friends who are not into birds. In response, the friend will look up, unimpressed, and say, “Hmm,” because all they’re seeing is another brown bird flying by.

 

Next I show my friend a close-up photo of the bird, and then they are wowed, and want to see the bird again. Often they say, “What’s it called again?” in earnest interest.

 

Cedar Waxwing juvenile

A gregarious bird, cedar waxwings are rarely seen alone. Sometimes you will see them foraging in small flocks, often in large flocks. Congregating in the sky much like starlings or blackbirds, small flocks join up  with other small flocks until there are hundreds of them flying in one graceful, swerving cloud.

 

Lately there’s been a flock of 500 that zooms by our balcony dozens of times a day. They like the cotoneaster shrubs in the landscaping.

 

More info at Cornell Lab of Ornithology. 

 

 

Other than a high-pitched thin whistle call that is out of hearing range for many people, they are quite silent as the flock synchronistically descends into a berry tree, shaking the branches, and plucking the fruit.

 

What a thrill to look up and see a bouquet of these chic birds dancing the skies.

Mud-Nesting Swallows

San Francisco Bay cove

There are many different kinds of bird nests, and one that I find especially interesting is the mud nest. I came upon cliff swallows building their mud nests last week in a cove of San Francisco Bay.

 

I was walking in a residential neighborhood at the shoreline, when I noticed two or three dozen cliff swallows swooping around the water’s edge. That day we had particularly low tides. In fact, in the four months I’ve been traversing this path, I have never seen so much exposed mud.

 

Cliff swallow pair gathering mud

 

The swallows were taking advantage of the mud opportunity afforded by this perigee phase of the moon (unusually close to earth).

 

In an area where there are usually ducks and cormorants swimming in the lapping water, this sight of the swallows fluttering in the mud slowed my disciplined pace.

 

I watched as the swallows used their bills to dig up little dabs of mud. Bills loaded with mud, they flew off to a nearby waterfront house; all flew to the same place, the underside of one house.

 

Superior flyers that they are, the swallows didn’t even pause at the extensive nets lining the underside, presumably installed to prevent this very activity. They effortlessly navigated through the net holes to the house’s beams.

Cliff swallows gathering mud from the shoreline

One after another, each individual delivered their mud pellets, turned around and glided right back to the tidal mud, and scooped up more. This went on for at least 15 minutes.

Northern Rough-winged Swallow at cove

There was no way to see or photograph the nests without a boat. But cliff swallow nests look like this.

They’re gourd-shaped, mud enclosures with a single opening.

 

Named for their behavior of building on cliffs, the cliff swallow has adapted, in the absence of cliffs, to building on human structures. They build under bridges, on highway overpasses, and other man-made structures, like houses.

 

Sometimes cliff swallows build fresh new nests, and sometimes they use old nests. They are colonial nesters and their living quarters can grow quite expansive. This swallow is known for their big communities, the species of the legend, the returning swallows of San Juan Capistrano.

 

There are about 80 species of swallows across the globe, occupying every continent except Antarctica. They don’t all build mud nests. The violet-green swallow, for example, is a cavity nester. I have witnessed their nest-building skills every spring in nest boxes on our property.

Barn swallows, the most widespread swallow in the world, also collect mud pieces for use in their nests. As their name suggests, they typically build in a barn or stable. Their mud nests are cup-shaped, usually built on a beam. Just like the cliff swallows, barn swallows require fresh mud for their nesting venue, and consequently nest near water.

Another swallow we encountered that day at the waterfront were the northern rough-winged swallows. They prefer to nest around water too, but build tunnels in the ground instead of nests.

Wherever you are, it’s always rewarding to observe birds building nests–the materials they choose, the places they set up house, and the devotion they declare in starting a new generation.

 

A toast to the mud-nesters: here’s mud in your eye.

Celebrating Earth Day, Las Gallinas Ponds

Mute swan with cygnets

For Earth Day this year I am happy to introduce you to the Las Gallinas Ponds, a place I have been visiting for nearly 20 years. This trio of shallow lakes is a humble but noteworthy example of how a large community has learned to integrate wildlife and human needs.

 

Las Gallinas is an Earth Day story. For over half a century humans and wildlife have been inhabiting this same functional space. It is more than just a park. It is an important facility in the San Rafael community, covering 400 acres and serving 30,000 residents.

 

As you walk around the three lakes and gaze upon the marsh and fields, you are greeted by birdsong and vast, open wilderness. Over 188 birds species live here, as well as mammals, reptiles, butterflies, and other wildlife.

 

Las Gallinas Ponds, San Rafael, California

Pair of Common Mergansers

 

This marsh on California Bay Area’s San Pablo Bay has a pedestrian walkway that winds around each lake. It is flat and wide, and a magnet for neighborhood walkers, joggers, bikers, and wildlife enthusiasts. It accommodates wheelchairs, strollers, and people of all ages; and is surrounded by mountains and bay.

 

Two of the ponds have small islands where black-crowned night herons, egrets, ducks and geese gather. In winter the waters are covered with migrating waterfowl.

 

Cattails and reeds host marsh wrens, bitterns, rails, and gallinules; while songbirds flit in the surrounding trees. I always see at least five different species of raptors cruising the open sky, including peregrine falcon, merlin, harriers, kites, and red-tailed hawks.

Snowy Egret

A few weeks ago, on Easter Sunday, we heard about a pair of mute swans on a nest, from other trail walkers.

 

We found the nest and waited patiently, knowing that eventually the mother would stand up, turn the incubating eggs. And when she did, she revealed a nest of five large eggs.

 

Mute Swan Wikipedia. 

When the swan stood up, we saw her eggs. Look closely underneath the swan.

The next Sunday when we returned, we found two fluffy cygnets tucked underneath Mom’s large wing.

 

That day we saw so much springtime:  wildflowers in profusion, mating cinnamon teal, the absence of most of the winter migrators, and the arrival of swallows by the hundreds.

Mating Cinnamon Teal

 

I truly love to be here at the ponds. But I do not bring friends unless they are hardy outdoor people…because it is actually a sewage treatment facility. Birders go wherever the birds are, but not everyone is so undiscriminating.

 

The ponds are holding tanks for human waste, called reclamation ponds. There are 200 acres of wastewater storage, freshwater storage, and pasture irrigation fields. There is also a field of nearly 3,000 solar panels for generating electricity. See diagrams at the end.

 

This sanitation plant not only opens their grounds to the public, but they also provide generous numbers of picnic tables and benches, maintain the grounds for visitors, and host school groups. There’s even a bowl of water for dogs. Their website is also inviting, with funny educational videos.  Check out “Can’t Flush This Song” and “Recycled Water Taste Test.”

 

When you first arrive, it looks like the processing plant that it is. There are many large tanks with huge churning arms, and lots of pipes in all sizes. Hundreds of gulls, red-winged blackbirds, and starlings hover over the stirring tanks.

 

The processing station only occupies the front section, and in two minutes you don’t even notice. The trail extends alongside the ponds, stretching out for several miles.

 

Northern Mockingbird

By this past Sunday, the third one in a row, we were nervous about what we might find at the swan nest. Who, we wondered, had been successful: the swan family or the predators? There are river otters, badgers, and coyote here who would love to crack into a big swan egg.

Good news. The two cygnets were still around, had even grown a bit, and they were earnestly paddling beside their parents. I don’t know about the other three eggs.

 

People laugh when I tell them I go to the sewage ponds for my birthday. They think I’m kidding.
