Gryphons and pools near the Salton Sea

On the way home from San Diego Audubon Bird Festival, E and I stopped at a location near the Salton Sea where Gryphons are known to snore and slumber.

Gryphons, in this case, are geothermal features: modest but surprising cones built up by mud pots burbling out of the flat salty floor of the agricultural land around the Salton Sea.  This gyphon patch is officially known as the Davis-Schrimpf Seep Field, and is in the midst of a geothermally active area sprinkled with power plants that harvest energy from spots where warm gases rise up through cracks from deep underground, heating the salty water and liquefied clays they percolate through.  The gryphons lie sleepily in a field at the corner of two agricultural roads, some with briny pools of their own, tinted by hardy algae in red and green and orange, and others dry humps rising from the salty, cracked dirt.

For our trip we were lucky: though the ground had been wet recently, it was dry now, and we could approach the drowsy gryphons without sinking too deep. Some growled and burbled from deep inside without disgorging their liquid contents, while others sputtered and bubbled brownish gray mud, sometimes thin like a melted malt, sometimes almost thick as pudding.  Even in the brisk wind that blew, a slightly sulphurous and organic smell could be detected.  E wished to sample the waters, and I was the lackey, scooping up clays and biofilms into Falcon tubes, prepped for biological sampling.  My hi-tech tools were a narrow stainless steel spatula and a lighter with a  WWF wrestler on it, so it was work I could be trained to do.  (Although having made that claim, I should add that the wind made using the cheap lighter difficult, and I actually worked up a blister firing it over and over to flash off the sterilizing ethanol between samples.)

Meanwhile, E handled the serious equipment for testing pH and conductivity of the pools (several times reading “over range”, since the water is a few times saltier than seawater), and a couple of hours passed while we collected data and samples, trying not to let papers and zip-bags blow into the pools in between.  Clumps of visitors, locals and their friends, mostly, but others from farther places like Canada, came and went, asking questions about what caused the mudpots, what we were measuring, and if it was safe to walk around.  Some folks climbed right to the top of active gryphons, unconcerned about their own safety or the condition of the formations.  So far, this area is unprotected, and visitors have been fairly good about being careful.  For now, the only marks people had left were footprints, and a few unwise vehicle tracks.  As long as that’s the case, the gryphons will probably remain unfenced, regally accepting conscientious company into their realm.

From the San Diego Bird Festival

Late post (Sunday 8 March 2009):

Hello from San Diego, where today is the last day of the San Diego Audubon Bird Festival.  Things have been busy here, and I haven’t had a chance to post until now.  The Festival is at the Marina Conference Center right on Mission Bay — here’s a shot of the Three Star Owl booth.  It’s nice to be in a room with windows and a view.  So many facilities are completely interior and have things like accordion walls with scotch tape holding up a leftover honeycomb wedding bell that was too high for the cleanup crew to reach.  This room is wood-panelled and bright, and looks out onto a marina.  Nice!

E was able to come along and help, which is a treat because then each of us had an opportunity to go on a field trip.  He’s doing a San Diego River outing as I write this, and yesterday I joined a pelagic trip out to the Islas Coronadas, a small grouping of islands in Mexican water within sight of San Diego.  The room is still swaying a bit this morning, although by Pacific standards the seas weren’t rough. My little camera doesn’t do distant birds well, so I don’t have a picture of what was for me the highlight of the trip, several pairs of small alcids (a type of sea bird) called Xantus’s murrelets, which, although we had great looks, would never be more than little black and white blobs bobbing on the waves in my photos.  There were many excellent sea birds to be seen, but also mammals, including close looks at Gray Whales migrating north, and four species of dolphins: Risso’s, Common, Pacific white-sided and Bottlenosed, who larked under the bows, close enough so that we could hear them exhale when they surfaced. Above is a photo of something my camera can handle — a California sea lion beach-master with his harem.

In case you’re a non-birder, and don’t know what birders do at bird festivals, the main events are organized field trips to local hot-spots, led by experts, to look at birds.  The exhibit room has exhibitors like state Fish & Game people or the American Birding Association giving out info, and vendors with bird and nature related supplies, photos, and art for sale (like Three Star Owl).  Optics manufacturers have reps there, so that attendees can check out scopes and binox.  Occasionally impromptu viewings break out, such as when a Merlin was spotted atop a mast in the Marina, and the line of demo scopes was commandeered for viewing.  Pretty heady times!

Stay tuned: on the way home E and I stopped at the Mud Volcano site on the Salton Sea for a spot of sampling and marvelling at gloopy mud-blorping “gryphons”.

Scoter addendum — the Arizona angle

In the last post on scoters, I forgot to add that there is a surprising Arizona angle to these sea ducks. Some years, one or two are found wintering or in transition on desert lakes around and about the state.  They are categorized as “casual” here.  This winter (Dec. ’08), there was a handful of female or immature-type Black scoters (white cheek patches) seen along the Colorado River near Parker Dam, and a White-winged scoter at Kearney Lake east of Phoenix (Jan. ’09; white cheek patches and white on the wings).

Arizona lakes and rivers contain populations of what are locally called “mussels”, both native and non-native bottom-dwelling bivalves.  Presumably these are what these wayward scoters are living on.

The bird above is a well-documented female Black scoter (Melanitta nigra), photographed at Butcher Jones Recreation Area on Saguaro Lake NE of Phoenix in October 2007.  Find more info and photos at the Arizona Field Ornithologists page.  If you’d like to check out the view or hike or kayak from Butcher Jones beach, here is a link with a map and other info.  Saguaro Lake is an excellent place for birding and hiking Fall through Spring.

Etymology

The etymology of the word “scoter” is obscure, with no satisfactory concensus. The scoter genus, Melanitta, is a Greek compound from Gr. melas, black, and “nitta” which Choate says “appears to be a misspelling for Gr. netta, duck”.  Most scoters are mostly or entirely black, so the choice is apt.  The Black scoter species, nigra, is the feminine form of Latin niger, black, which makes it a black black-duck.  The Surf scoter species, perspicillata, is from Latin and means “conspicuous” (like the Spectacled owl, Pulsatrix perspicillata).  They should just get it over with and say “clownlike”, right?

Life bird at the Mall: the Salt River at Tempe Town Lake

Internet emailing list services — “listserves” — are an excellent way for birders to spread the word about what’s being seen in the area, and useful information about how to get there, which tree it was sitting in last, and which landowners show up with cookies and which with a shotgun.  But a birder cannot live by list-serve alone.  Sometimes I forget this, or get too wrapped up in the “art birds” in the studio, and not the real birds that are out there which inspire them.

So Sunday, though it was very wet at times because of a robust late winter storm that’s bringing snow to Arizona’s peaks and rain to its deserts (=wildflowers!!!), E and I went to view Da Boids at the Salt River east of the east end of Tempe Town Lake, otherwise known as “Tempe Marsh”.  We went with friends who get out more than we do, which was a good thing because there was a surprise there I wouldn’t have given a second look at without a knowledgeable nudge in the ribs.

For those who aren’t familiar with it, Tempe Town Lake is a stretch of the Rio Salado (or Salt River, the jugular of Phoenix) on the northern edge of the city of Tempe, just east of Phoenix and south of Scottsdale. In the late 1990’s, engineers took the unusual action of damming the Salt at two places with huge black inflatable rubber tubes stretched from bank to bank.  (The fall of the river is so flat here, that putting in just a downstream dam wouldn’t create usable depth.)  The dams take advantage of a “gaining” stretch of the Rio Salado.  At this point underground river water is naturally forced to the surface by bedrock (ASU’s A-Mountain and other visibly hard features jutting up out of the flatlands) and the dam slows this water and pools it together with added recycled water.  The combination of human engineering and natural geology enable what on the surface often appears to be a feeble desert river to create a body of water significant enough to allow the public to fish, boat, scull, and reflect on the unappealing commercial buildings the City of Tempe has blighted A-Mountain with.  If you remember the area from earlier days, it’s quite a change to the scenery to drive by downtown Tempe on the elevated Loop 202 freeway and see its bridges and buildings reflected in sun-catching wavelets.

One of the activities enhanced by this sudden advent of standing water is birding.  Or, to be less anthropocentric, the new lake created habitat which has attracted a good number of waterbirds, waders, and shorebirds, as well as raptors and some landbirds (in the willows and cottonwoods that seem to spring up nearly overnight).  All these in turn have attracted birders.

It’s drive-up birding, and definitely not pastoral.  It isn’t quite as gritty as birding the landfill or most sewage lagoons, but it’s not wilderness.  It’s very….suburban.  With the sun at your back you stand at the edge of the parking lot for the mega retail complex called Tempe Market Place (hereafter TMP).  It’s necessary to block out the piped-in pop music drifting across the asphalt from the shops, and to try to ignore the inviting odors of grilling carne asada telling you that your breakfast was only oatmeal, and really early in the morning.  On an afternoon visit, you may vie for parking with movie-goers, and Fridays are the worst — the scene includes local bands playing at “the District”, the “lifestyle” part of the outdoors retail vortex.  The most obvious features of the landscape, though, are the roads: the Mill Avenue bridges, placed at the historic Rio Salado ford and Hayden Ferry crossing (for many years the only crossing on the Salt in Phoenix), and the the raised causeway portion of the Loop 202, the Red Mountain Expressway, looming over everything.  The sound of traffic is sometimes hard to hear birds over.  And bring a scope, because most of the birds are at a distance.

But there are birds to see.  Double-crested and a few Olivaceous cormorants are everywhere: flying in and away in skeins, hung out to dry in drowned snags (photo right), swimming with just head and neck exposed.  An Osprey cruises by, then a Red tailed hawk, and a Belted kingfisher barrels thorugh, rattling.  There are sandpipers, and killdeer, and coots and their more colorful cousins, Common moorhens; red-winged blackbirds and grackles; grebes of two species; egrets and herons; a group of Rough-winged swallows passing through.  And there are ducks: Gadwall and Mallards, tons of Shovellers, and teal.  This morning a pair of ornately plumaged drake Wood ducks (one seen in photo left) are floating together in and out of the cattails, looking exotic although they are not uncommon in the winter here, and breed elsewhere in the state.

What keeps birders coming here, though, are the occasional surprises.  Sunday’s surprise (at least, to me — the others were looking for it since it’s been observed in this location at least since January) was a long-distance visitor hanging with the local Green winged teal: a Common or Eurasian teal, Anas crecca.  This is a bird that should be in Japan in winter, or in Turkey, not Tempe.  Remember Bugs Bunny’s “I shoulda toined left in Albuquoykee?”  These things sometimes happen with migratory species; they get blown around, or take a wrong turn.  But I was glad our friends were on top of things, and pointed out the different field marks, because they’re subtle enough so that at a distance I easily skipped over them. Our bird was too distant to photo, so to the right is a photo by Michael Moore of an individual seen last year at the Gilbert Water Ranch, not too far from Tempe Marsh.  Since a picture’s worth 1K words, I’ve also included below a photo by ASU prof Pierre Deviche of a local Green-winged teal for you to compare: note the prominent vertical breast bar on the side of the local teal, and the more prominent white head lines on the Common teal.

For you sticklers for accuracy, I should note that although I’ve called this a “life bird” sighting for me, technically it isn’t: the two birds, our local Green-winged teal and the Common teal, are currently considered by American authorities to be sub-species of the same species, Anas crecca.  But the taxonomists may be about to split them, so I hear, and I’ll be ready!

Until then, I’ll just have to be inspired by seeing the two together, and add Green-winged teal to my “list” of birds-I-make-art-from, which is low on ducks at the moment.  Because who can resist that cinnamon-and-green noggin?

Increments: Color me vulture (Sarcoramphus papa), plus a quick field trip to Belize

Another reason I’ve had vultures on the brain is because I owe a friend a vulture.  Specifically, a king vulture, Sarcoramphus papa, the largest of the Cathartids, the New World Vultures.  They are the largest vulture in our hemisphere if you don’t count the two condors, and they are striking birds (literally — I was given a hammery-beaky once-over by one in captivity long ago, but that’s a different post), with black-and-white plumage and a bare-skinned, froot-loops colored head roped with chicken-skin folds.  If that weren’t enough, both genders sport a caruncle on the top of their bills: a warty, fleshy, bright orangey-yellow knob whose purpose, frankly, I don’t know, if not to gild the lily.

So, here is Jack’s King vulture, in progress, Increment 1.  Having modeled the bird, it awaits slip, with a photo behind for plumage color reference.  I’ll give it a base coat of slip (“paint” made of clay, mineral colorants, and water) in appropriate colors while the stoneware is still damp.  Once it is completely dry, it will go into its first (or bisque) firing.  After that it’ll get glazes and other finishing colorants applied, and be fired again.

As usual with clay, the heaviness of the material requires support, so I’ve had to fudge some physical realities: I can’t make the legs as thin as they are in nature, and I’ve used the wings as the third point of support so the bird stands by itself.  Normally, a vulture’s wings, as ample as they are, don’t reach the ground in a standing bird. But other typical characteristics will carry the likeness through: the hunched posture, the partially opened wings, the body plumage color, and of course, pleated froot-loop head.

Increment 2: Slip treatment.  In this case, the slips were applied with a brush.  They will not acheive their finished colors until the final Cone 5 firing.  For now, the black looks brown and the white looks grayish.  The froot loop colors will be applied as glazes, after bisquing.  Now this guy will sit until he’s TOTALLY dry.  Also, his body is hollow, and this time I did remember to pierce an inconspicuous hole to the cavity.  Stay tuned for later posts for finishing touches.

Most of us think of vultures as being all-dark birds, like Turkey vultures.  But there are predominantly white vultures, like the King.  In the Old World, the Egyptian vulture, also a vulture primarily of hot climates, is mostly white-plumaged.  You would think a large white bird would be disadvantaged by being easily seen.  Actually, King vultures, when roosting and nesting in their tropical forest habitat, are surprisingly difficult to see.  Their white feathers reflect the green light passing through the foliage around them, making them blend in quite well.  They are somewhat shy despite their regal reputation, and tend to assume a self-effacing posture when perched on a limb.  A King vulture in Belize “hid” from us this way.  We spotted it on the ground in a field.  Feeling our “eyeball pressure” it felt safer flying up into a tree, where it hid its head behind a tiny clump of foliage.  The rest of its enormous body remained in plain sight, but it felt better, and would peek out from the leaves occasionally to see if we were gone yet.

In the air, an all-white bird glints in the sun, but of course, up there, they’re out of reach, especially at the altitudes King vultures acheive.  It’s a spectacular sight to see the bright wedge of a King, as white and as large as a pelican, rising on thermals over a mahogany forest.  The photo below is of just such a Belizean forest as a King vulture would favor.  Imagine one soaring just out of frame, with Bat falcons, Swallow-tailed kites, White hawks and other tropical birds of prey swirling on the updrafts from the Escarpment near Chan Chich, one of the few places in that flat country where you can get out and up over the forest.

Greetings from Willcox

Fortunately, I was able to hook up with V on her scouting trip this morning, and this is where we went: the dawn lift-off of Sandhill cranes just south of the town of Willcox, AZ.

Above is a photo of a small fraction of the cranes flying out from the ice-crusted ponds where they spent the night — something like 6 or 8 thousand roost at this place.  Dos Cabezas peak in the Chiricahuas is the twinned topography in the distance.  The sound the cranes make is as much a part of the spectacle as the sight of thousands of birds in wheeling lines overhead.  It’s an amazing noise, which I haven’t found an adequate way of describing.  A croaky sort of rattly trumpeting, continuous and amplified and multiplied by thousands of syrinxes, it’s mixed with the baby-piping calls of immature birds urging their parents to wait up, distinct above the stuttery honks of the adults.  (I’ve got a great video clip with the sound of the lift-off that I’m currently unable to get the editor to accept; I’ll post as soon as that struggle is over…)

An immature Golden eagle momentarily fools us all into thinking it’s intent on a crane on the fly, but it turns out to be adolescent high jinx and it perches on a power tower instead, after creating a fuss in the air, and setting most of the remaining cranes into flight.  Earlier, a handful of Chihuahan ravens hadn’t done as efficient a job of agitating everyone.

The cranes fly out to feed in the stubbly fields of Sulphur Springs Valley during the day: here’s a telephoto shot of a group working in a field with an irrigation pivot looking like a fence behind them.  They move slowly but steadily as a group, pecking the ground and occasionally each other, challenging breast to breast and vocalizing if necessary.  An occasional stick is brandished boldly, and there is some hopping about, with stick.  The immatures have brownish crowns, the adults a bright red heart-shaped “shield” between the base of their bill and their crowns.  Not visible in the picture, a big Ferruginous hawk lurks over the crowd, perhaps waiting for the probing bills to stir up a rodent, and American kestrels follow the foraging flocks as well. The cranes themselves often seem to follow the field equiptment, poking through freshly turned soil for goodies.  Horned larks work the furrows too, a Loggerhead shrike emits a variety of calls from a power line, and Eastern meadowlarks in large numbers stalk purposefully over the clods.  All of these birds, like the farmers, make their living off the soil of the Sulphur Springs Valley, and to some degree their numbers and even presence are due to agriculture.

In Willcox,  Land of the Cranes, they are everywhere: back at the motel, a solitary crane poses obligingly on the commode, but its stately blue silence has little in common with the mobile, gabbling gray thousands we’ve just witnessed.

Three Star Owl at Wings Over Willcox

For those of you within range of southeastern Arizona, consider visiting the annual Wings Over Willcox Nature Festival this weekend.  Held in the historic community of Willcox, this event celebrates the yearly return of tens of thousands of Sandhill cranes to the Sulphur Springs Valley in southeastern Arizona.  The rich Chihuahuan desertscrub and grasslands are slung between the Chiricahua Mountains and the Dragoon Mountains.  Patched with mesquite bosques, farmland, rangeland, and dotted with pools and ponds of semi-permanent and seasonal water, the Sulphur Springs Valley is winter home not only to the cranes, but to extraordinary numbers of birds of prey, sparrows and longspurs, waterfowl, shore birds including upland varieties, and other bird species people may not commonly associate with our region.  Scaled quail, Eastern meadowlarks, Bendire’s thrashers and Mountain plovers lurk in the wintery fields along with more expected Roadrunners and Gambel’s quail.  It’s a land of agricultural heritage — hydroponics and hay, and ranching, too.

This close to the event, many of the fieldtrips are filled, but check at the registration desk in the Community Center for last minute cancellations.  Also, many of the sights, notably the crane lift-off at Whitewater Draw and elsewhere along the farm roads in the Valley, are something you can do on your own.  The WOW organizers can give advice on where and when to go.

This year’s festival is the sixteenth annual WOW, and it’s the second year Three Star Owl has been in Willcox for the event, offering Arizona-specific table wares and sculptural items both funky and sensible.

Come visit “The Owl” at:

Booth 12, Willcox Community Center, 312 West Stewart Street, Willcox, AZ

Friday 16 Jan: 10am -7pm

Saturday 17 Jan: 8am – 5pm

Sunday 18 Jan: 8am – 3.30pm

Pitching a Pleistocene Fit: when relict megafauna acts up

The last post was about really big mammals that seem on a scale with mammoths, condors, and whales.  That’s the thing about the Western US, you can never be sure when you’re going to run into some immense mammal, left over from the Ice Age:

E does field work in Yellowstone, so I have an acquaintance with relict Pleistocene megafauna. Once when we were at a back-country hot spring taking measurements, someone stood up and said, “What’s that?” Everyone stood up and looked, and saw a Grizzly Bear. I stood up too, but the autumn grass was tall, and all I could see was a brown woolly hump lurching closer.  It could have been anything, a moose, an elk, a ranger. But it was a bear, scavenging old bones where bison had gone to die on a warm thermal hillside. That’s when I realized how effectively height is selected for in humans.

It’s easy to be afraid of a grizzly bear, but it’s smart to be afraid of a Bison. Even if you know how fast and big they are, they’re actually even bigger than that, and much faster. Not long ago I ran into one, not in Yellowstone, but on Catalina Island, on a hike up to Butt Hill (its real name) above Two Harbors.  I was alone, coming down a “social trail” — an informal path made by people’s feet rather than Park Employees’ shovels — and as I came out of a shrubby oak woods (see photo on right) onto the official road from above, a Bison came out in the same place from below. He was headed up hill, up the trail I had just come down, and was Not At All Pleased to see me. He began to snort, and kick clods, and in general act like a Warner Bros. cartoon bull, except not funny a bit. I sidled up to a shrubby little oak with spreading branches figuring I could climb if it came to that. The bison was only about 15 feet away, so I held very still. After more macho display, he moved off a short distance.  But then I moved slightly, and it set him off again, scuffling dirt and huffling snort and hopping around rocking back and forth, wagging his huge bearded head over his fore-hooves, like an owl “toe-dusting”. The problem was that he had moved off down hill, where I needed to go, and I was standing where he wanted to go. All I could do was hold still until he stopped doing Crabby Boss-man Dance, imagining being late for dinner at the conference dining hall, which seemed very very very far away from that scrubby oak woods, trying to not think what a bison horn would feel like hooked under the ribs. Eventually he stopped acting thuggish (I swear it felt like an hour, but it was probably only a couple of minutes), then he moved off behind some trees, uphill, and disappeared. I stuck to the crummy oak for a few more minutes and then picked my way down hill, on the downhill side of the trail, saying intelligent-sounding things like “Ho, bison,” and “Hey, bison,” so it would know I was there and not be surprised. The rest of the hike was treeless, and I kept looking over my shoulder for the big angry animal, but I never saw it again.

Bison aren’t supposed to be on Catalina Island, but like a lot of things living in Southern California, they were left behind by a film crew. In 1924, so the story goes, 14 bison imported to the island for a film version of Zane Grey’s “Vanishing American” were left to fend for themselves. They did, for better or worse. To judge by the number of close-call videos posted on You Tube, I’m not the only one who’s had an adventure with one of them. I didn’t get photos: the last thing on my mind at the time was the camera.  So my only record of the actual encounter is the Fauxtograph and sketches from my journal included here.  (The very telephotic picture just above shows a bison at a distance — probably the same one I ran into later, but I never imagined he’d cover so much terrain so quickly.  He’s the brownish deceptively tiny blob in the brightest green patch of grass, lying down calmly chewing cud.)

Nature is unpredictable: the next day I came down with a horrible cold.  I’d been worried about being gored on the spot, but instead I was laid low by a bacterium or virus, and was miserable for days. I’ll bet the bison never even gave the incident a second thought.

In memoriam: favorite rust-colored bandanna lost at some point during the escape, when it fell out of a pocket.  On the other hand, I ask: is it smart to hike in bison country with a reddish flag wafting at your side?…

Photos: A. Shock.  Yes, it’s a plastic bison.  That’s the fauxtograph.  Left: bumper sticker on the gear box of a Colorado River raft.  I’m sure the Condors would appreciate Pleistocene rewilding, too.  I’m not so positive: Bison are bad enough, but Short-faced bear and Smilodon?  Don’t know about hiking with those guys…

Pleistocene megafauna trivia

It’s a fact that Lewis and Clark were told to look for Mastodon dead or living on their exploratory jaunt out West, because the terrain was little enough known that the cognoscenti back East weren’t absolutely SURE they were extinct.  Besides, Thomas Jefferson (right, B&W) wanted to prove wrong the eminent French naturalist Georges-Louis Leclerc, Comte de Buffon (right, in color) who claimed that the degenerate North American environment couldn’t support a robust fauna (including its humans).  Jefferson was a big fossil enthusiast, and had a relatively new shiny country to defend against Old World criticism of not coming up to snuff.  To refute Buffon’s claim, so the story goes, he dispatched US soldiers into the north woods to shoot a bull moose to ship to France for display, but Jefferson felt it was necessary to substitute a more impressive rack from another individual to bolster his case that the fauna of North America was indeed macho.

To come back full circle to our bison, it has a prominent place in a monograph Jefferson wrote in response to Buffon’s claim that America was a land “best suited for insects, reptiles, and feeble men.”  Jefferson pointed out that quadrupeds occurring only in America not only out-number by four to one quadrupeds unique to Europe, but that one of them by itself, the American Bison, actually outweighs all of the indigenous European quadruped species combined!

Left: Peale’s mastodon, the critter that everyone was talking about in 1803.

Elephant seals of the New Year, but not Año Nuevo

After the family Christmas gathering, E the M and I made our way down the California coast towards the M’s house.  Every few years we find ourselves doing this, stopping sometimes in Santa Cruz, sometimes Big Sur or Davenport, but more than once in Cambria.  The twee shops in the village don’t draw us as much as the surrounding coastal landscape, gentler and less remote than the raw edge of the Big Sur coast (that jagged and temporary fringe of an entire continent): it’s less dramatic but more accessible.  Humans are not the only organisms to find this coast attractive: Sea otters, harbor seals, dolphins, and gray whales can readily be seen in season in these waters; also, northern elephant seals.

In our long ago years at Santa Cruz, E and I would visit the elephant seal rookery at the point Año Nuevo, in those days the only place the enormous pinnipeds were known to haul out on the mainland.  The visit involved advance reservations and a naturalist-led slog through seal-festooned dunes to a viewing point looking down on the rookeries and the island lighthouse of Año Nuevo, in which, the story was told, the lighthouse-keeper’s claw-footed bathtub still contained the skeletal remains of an elephant seal that had crawled into it to die.

So, imagine our surprise when we pulled off from Hwy 1 to hike a bluff trail just north of San Simeon — a hundred miles south of Año Nuevo — and looked over to see a heaving heap of snorting, snoring blubber, jostling and making the same distinctive bladdery croaking sound (described as a Harley starting up in a gymnasium, listen here: 02-alpha.mp3) that we remembered from the rookery north of Santa Cruz.  Since 1990, Elephant seals have colonized the narrow strands stretching south of Piedras Blancas lighthouse, and each December, they return to give birth and mate on these beaches.  Viewing them is easy — a couple of  parking areas have been built atop the bluffs along coast Hwy 1, and low-visibility fences are in place to separate scarred, cantankerous males from pesky human voyeurs.  By mid-December, bulls have staked out their section of beach, and cows are lying about in harems.  The real draw, though, is the young of the year: wrinkled black-furred seal pups lying at their mothers’ side, chirping and bawling until she rolls over to expose a teat, or, rather, a slot where the teat lurks.

We’ve never been lucky enough to see an actual birth, but we’ve seen such newly-born pups that gulls and Brewer’s blackbirds were still fighting over afterbirth among the sandy heaps of seaweed. Last year 4000 pups were born just in the Piedras Blancas rookery, and they’re expecting similar numbers this year.  The density of seals is astounding: in addition to hefty 1600 pound cows, massive 4500 pound bulls, and an assortment of bulky young males, there are piles of blond yearlings lying about in the dunes, snuffling and spraying briny snot on one another, occasionally engaging in mock baby-fights, baring their teeth and striking at each other in practice territorial behavior, then falling back into a doze piled together in heaps like bleached drift logs.

For those of us less inclined to gawk at the unnatural concentration of the world’s riches crammed into William Randolph Heart’s folly (the ersatz Moorish castle overlooks the rookeries), the Piedras Blancas elephant seals put on a different type of oversized spectacle.  Check out the website of Friends of the Elephant Seal for more info and images.

A tip to would-be visitors to Piedras Blancas Rookery: Because viewing access is easy here, there are lots of people, and parking can be problematic.  So, go early (before 10am) or late (after 4 pm, and sunsets can be spectacular!).  Or, visit alternate viewing sites along the same coastal bluffs, where you will see fewer seals, but fewer people, too.  For a less drive-up experience of the seals than at Piedras Blancas, take a hiking tour out to the rookery at Año Nuevo, but don’t forget to get advanced reservations for peak breeding months (Dec -Mar).

By the way, if curious architectural follies of eccentrics do appeal, drive by the eclectic Nitwit Ridge in Cambria, in disrepair but surprisingly resonant with Hearst Castle.
