Brewer’s Blackbird (sketch by Heath Massey)

A fairly common bird in Golden Gate Park, the Brewer’s Blackbird (Euphagus cyanocephalus) is easily recognizable by it’s bright yellow eyes and blue-black plumage.  The iridescent blue-green sheen of the male is gorgeous in the sunlight, belying the dull-sounding “blackbird.”  Often lined up on telephone wires or flying in flocks that gracefully rise and fall, these birds are well adapted to urban parks.  But sometimes they miscalculate.     Here’s a funny video of a Brewer’s blackbird defending an ill-considered choice of real estate in Golden Gate Park (near Stow Lake).  The video was made by Mila Zinkova in June, 2014. https://www.youtube.com/watch?v=7qQcM9yytSI#t=27

How tall was John McLaren?

Statue of John McLaren, Golden Gate Park (sketch by Heath Massey)

Statue of John McLaren, Golden Gate Park (sketch by Heath Massey)

The statue of John McLaren in Golden Gate Park is a little bit shorter than I am  (I’m just under 5’7″).  Is it life-sized, I wonder?  Somehow I always imagined John McLaren as a major physical presence, given the stories about the fear and trembling that he induced in his gardening staff.  (see former post: http://fromthethicket.com/2010/10/09/john-mclaren/) Come to think of it, though, the man depicted in the statue, although not tall, is actually quite intimidating.  Bald and portly, with military bearing and deep-set eyes fixed on a pine cone, he seems formidable.  I would hesitate to cross him.  Obviously stature is about much more than physical size.

the bowling lawns in golden gate park

Lawn bowling in Golden Gate Park (sketch by Heath Massey)

Lawn bowling in Golden Gate Park (sketch by Heath Massey)

The bowling lawns in Golden Gate Park are vivid green and very flat, a striking backdrop to the traditional white that lawn bowlers wear on tournament days.  To me these lawns are beautiful, but they also look almost unreal, more like carpeting than grass.  And like antique carpets, they seem to be showing signs of age.  I wonder how they are constructed and what kind of maintenance is required.

A search of the literature reveals that, not unexpectedly, the design and construction of a bowling green is highly specialized.  The substrata must be perfectly graded and compacted to support the growing medium (soil) with absolutely no shifting or slumping.  A drainage system installed beneath the green removes excess water quickly.  The soil is engineered to retain water and nutrients, withstand compaction and drain well.  The surface must be 100% flat, so once the substrata is compacted and graded, the growing medium is installed in thin layers and rolled after each layer.  While hand methods were used to level the surface of bowling greens for many years, a machine mounted laser level is often used now.  The turf grass must be carefully selected not only with local environmental conditions in mind, but also to withstand the stress of frequent close cutting, compaction and high wear.   Irrigation must be designed to deliver water evenly over the surface.  Whew!

This summer the oldest bowling lawn (#1), nearest the 100-year-old Club House, is undergoing renovation.  It’s interesting to watch the process and it will be great to see the results.  The scope of work appears to include repairing parts of the drainage and irrigation, replacing the rotting wood edging that surrounds the green (with concrete), adding new ADA walkways, repairing benches and fences and adding new planting to beautify the edges.  Parts of the bowling green will also be brought back to level by addition of sand (around the edges, at least).

So here is my remaining question:  What about gophers?

I often wonder about the impact of the current  drought on Golden Gate Park.  Here’s an uplifting article about the water supply at the aquarium in the California Academy of Sciences.

‘The Steinhart Aquarium at the California Academy of Sciences opened at its new home six years ago with an ambitious overhaul of the way it delivers water to fish – and penguins and octopus and, of course, Claude, the popular albino alligator.Engineers laid some 10 miles of pipes and filters beneath the museum so water would be quickly and thoroughly cleaned for exhibits on coral reefs and rain forests. They also shut off an old supply line that brought dirty seawater 3 miles from Ocean Beach to the Golden Gate Park site. Now they cook up their own saltwater cocktail for the tanks.While the changes were expected to save water – a lot of water – the real payoff is coming now as the state wrestles with its worst drought in decades.”The academy is a crown jewel of how to take a structure that is historically very inefficient and a use thats very inefficient and really lead by example on how to reduce consumption,” said Benjamin Osgood, chair of the San Francisco branch of the U.S. Green Building Council.’

monterey cypress

Monterey cypress in the Botanical Garden (sketch by Heath Massey)

If there is one iconic tree in Golden Gate Park, I think it would have to be the magnificent Monterey Cypress that stands by itself on a small knoll in the great oval lawn just inside the main gate of the Botanical Garden.   This specimen has grown to an impressive height with a gorgeous, spiky, horizontal branching pattern and the dark green, clumping foliage so characteristic of the species.  The Monterey Cypress (Cupressus macrocarpa) is native to only two small groves on the Monterey peninsula, the larger grove extending about two miles north from Pebble Beach and the other at Point Lobos to the south.  But these trees adapt beautifully to foggy, coastal, wind-exposed locations and are widely planted throughout California, especially along the coast.

"Monterey Bay," Arthur Mathews (1860-1945), n.d.

“Monterey Bay,” Arthur Mathews (1860-1945), n.d.

Their wind-sculptured form has delighted artists since the nineteenth century.  Arthur Mathews springs immediately to mind, but many others have also painted these amazing trees: http://www.tfaoi.com/aa/6aa/6aa191.htm

The lower branches die as the trees mature and older cypresses naturally develop a distinctive, spreading, vase-shaped crown.  In parks and other public spaces the lower limbs are often removed for public safety, which leads to exaggerated, tall, top-heavy silhouettes that are also very beautiful.  In any case, these trees are so expressive, it’s no wonder poets also find them fascinating.  Here’s an example:

MONTEREY CYPRESS
By: John Malta

I, a cypress, in my seed
Knew the ocean was my need.
In the close and secret life
Of my core I learned that strife
Of wind and surge on thudding sand
Was for me: I must withstand
Anger from the sea that came
Farther than the western flame;
I could speak the west wind’s own
Language as it blew me down.

Windless days I grew to sea,
But wind made me grow back on me;
Where my growing changed I spread
Newer elbows round my head;
I am old and where I branch
The thews are thickened to be staunch.

Now behold I am a page,
Writ between repose and rage.
Carven to the smallest trace
The sea is in my tortured grace.
Naked bear I lettered limbs
Annotated by her hymns.

butterflies in golden gate park: anise swallowtail

Anise swallowtail butterfly at Strawberry Hill, Golden Gate Park (sketch by Heath Massey)

I have been noticing butterflies in the park lately.  This Anise Swallowtail (Papilio zelicaon) was flitting around a patch of yarrow and sticky monkey flower near the reservoir above the falls on Strawberry Hill this past week, while I was busy sketching a Red-tailed Hawk.  Then it perched for a long time, so I snapped a picture and drew this from the photo later.  I find that drawing fixes the markings in my memory much more permanently than taking a photograph;  now I will definitely recognize an Anise Swallowtail next time I see one.  There are about 35 species of butterflies in San Francisco, listed by local lepidopterist Liam O’Brien on his website:  http://sfbutterfly.com/www.sfbutterfly.com/SF_Index.html

I also own the wonderful Field Guide to Butterflies of the San Francisco Bay and Sacramento Valley Regions,  by Art Shapiro, illustrated by Timothy Manolis, which has a long and informative introduction explaining butterfly life cycles, behavior, population dynamics, effects of climate change, plant associations and much more.   From this book I learned that the Anise Swallowtail is a fascinating and adaptable butterfly!

The species Papilio zelicaon has been remarkably flexible in response to dwindling numbers of native plant hosts that once sustained it.  It is found throughout the temperate Northern Hemisphere, but there are many “ecological races,” meaning localized populations that have adapted to different ecotypes.  Its common name reflects the fact that it long ago adapted to breed on naturalized non-native species of the carrot family (i.e. “weeds”), particularly sweet fennel (anise).  Fennel was already in California by the Gold Rush and  Anise Swallowtails were observed feeding on fennel here in 1850 by the French forty-niner Pierre Joseph Michel Lorquin (California’s first recorded lepidopterist).  Fennel grows abundantly along roadsides and in vacant lots,  sustained by runoff from urban roads and back yards, and it affords edible material year round.  Anise Swallowtails that rely on fennel are multivoltine, meaning they go through the lifecycle multiple times during the year.  But in areas where there is little or no fennel and they breed on other plants, they may have only two life cycles per ear (bivoltine) and even just one life cycle per year (univoltine) in serpentine areas in the Coast Ranges (e.g.  Napa County).  This is a surviver species!

I think the butterfly I saw was probably a male, “hill-topping.”  Just hanging out there in a sunny, late afternoon, exposed spot, looking beautiful and sexy, hoping to attract a female.  I didn’t detect the scent of pheromones, but then I’m not a butterfly.

zen in golden gate park: the art of nature journaling

Nature journal, oak woodlands, Golden Gate Park (Heath Massey)

Nature journal, oak woodlands, Golden Gate Park (Heath Massey)

Recently I spent a week in the Sierras “nature-journaling” with John Muir Laws:  http://www.johnmuirlaws.com  If you aren’t familiar with Jack Laws, I highly recommend getting to know him.  Whenever I’m in the Sierras I depend on The Laws Field Guide to the Sierra Nevada and The Laws Guide to Drawing Birds (2012) has become a staple in my art library.  But nature-journaling with Jack in the Sierras was truly a transformative experience.  His approach to sketching in the wild combines the focused observation of the naturalist, the spiritual sensibility of the zen maser and the acute visual sensibility of the artist.  In the two weeks since that workshop in the Sierras, I have been seeing Golden Gate Park quite differently.

The main difference is that birds, insects, plants and all the other living pieces of the park’s ecosystem have come sharply into focus for me.  In the oak woodlands, for example, I no longer see primarily a landscape painting, although that frame is always with me too.  I also notice the gray squirrels (Sciurus carolinensis?) scampering along the branches, the dark eyed juncos (Junco hyemalis) feeding on the ground and the hummingbirds (Calypte anna?) chasing each other in the air like kamikaze planes.  I wonder if those hummingbirds feed on the alluring orange, trumpet-shaped flowers in that enormous patch of South African bush lilies (Clivia miniata).   Where do the squirrels and juncos nest?  Are there beetles in that pile of thorny blackberry canes?

With this new sensibility I sit still in one place longer, soaking everything up, watching and wondering,  trying to figure out what’s happening here, following the narrative of the place.  I go home and look up everything I’ve seen.  The park seems so much more alive.  I’m falling in love with it all over again.  Thank you Jack Laws!
