Gila monsters (Heloderma suspectum) are large stumpy lizards with bright handsome markings that are both cryptic and aposematic simultaneously, and whose hands look like neoprene wetsuit gloves with claws.  They are remarkable for being one of only two venomous lizard species in the world.  They live in the Sonoran and southern Great Basin Deserts and love to eat quail eggs, nestling birds and mammals, and other slow-moving prey items. (Below: captive gila monster on a wooden schoolhouse floor, photo A.Shock)

Approximately life-sized clay Gila Monster “bowls” are items I only make one or two of per year or so. They’re quite time-consuming, since they’re textured, slipped, and glazed pretty much beaded scale by beaded scale.  Here’s one now :

1)  I form a blob of clay that looks like a gila monster.  This early stage is the time to get any sinuousness in the tail, neck and belly, so the clay “remembers” it.  Then it’s time to put the wet lump aside to set up, or stiffen slightly, so that it can be shaped further.  Sponges help hold a pose, if desired.  >>

2)  As the water leaves it, the clay becomes more self-supporting.  While waiting for this to happen, I make legs — oddly spindly for such a stout body — with blocked out feet, to stiffen for adding later.  I also hollow out two thick places in the monster body, to aid in drying: the head, and the base of the tail.  This also makes the completed piece lighter and better balanced.  It is important to make a tiny, invisible passage into the hollow part from the outside, to let air escape during firing, or there could be an explosion.  <<

3)   With the clay slightly stiffer, I smooth the shape into its final form, including carving the toes from the blocked-out “hands”, and rounding the belly “bowl” part.  This shape causes herp boys to giggle, because it makes the lizard look like roadkill to those with scavenging permits for heloderm pelts.  From my point of view, it makes the piece functional, if desired: an Effigy Vessel, and not just a representation.

4)  The next step is to attach the legs, and texture the skin.  This must be done at a particular point of dryness, when the clay is still wet enough to accept the stamps I use to make the “nail-heads” in the skin (Heloderma means “nail-skin”), but stiff enough to hold up to the handling and pressure of stamping it.  Then it’s waiting for it to be bone-dry for slipping (right).  >>

The belly-texture, which looks like pink-and-black Indian corn on the cob, is carved into the clay rather than stamped — this is particularly time-consuming, especially for a part that isn’t seen very frequently.  Early on, I searched the web for a reference photo for Gi-Mo belly-scales, and never found one.  Fortunately, I persuaded a handler at a wildlife education event to flip a live one up for photos (she held it vertically, not upside-down), and got this great shot, which tells me all I need to know about what the unders of a monster look like, including vent details (<< left).  You can just see the heavy-duty cowhide welding gloves the handler was wearing; they were covered with black half-moons: venom-marks from previous crabby bites.  <<

5)  Slipping an item bone dry is slightly risky, as adding water to a piece at this point can cause cracking.  But adding slip to a dry surface gives a crisper, less texture-obscuring coating.  I use a combo of commercial under-glazes and slips I make in the studio.  It’s necessary at this point to choose the subspecies: the banded H.s. cinctum from the northern part of its range, or H.s. suspectum from the southern part, which has a more complicated reticulated pattern.  This one is kind of a combo. >>

6) After bisquing, I glaze the piece with dots (another labor and time-intensive step), each dot on the raised nail-head part of the texture, with a combination of black and pinkish-orange glazes.  After it’s fired, this adds depth of color and a glint to the lizard’s skin, similar to the fresh skin of a newly-molted lizard.  Sometimes, I add a leather tongue, if the monster’s mouth has been made slightly opened.  I’m looking into making a fully-open mouth next time, with wire teeth, giving it a really venomous-looking gape.  Here’s a shot of the finished version, a little more bulbous than an authentic lizard, but — after all, it’s a bowl:

Etymology

As mentioned above, Heloderma means “nail-skin”, for the fact that the monster’s skin looks studded or beaded rather than scaled.  suspectum, the species name, comes from the fact that early herpetologists were uncertain if the animal were venomous or not, and only suspected it was because of anecdotal accounts of its potentially lethal bite.  Eventually it was confirmed by laboratory experiments, and dissection, which revealed the large venom glands in the lower jaw.

It looks a lot like a toad, with a stumpy physique and warty skin, but it’s a Canyon Tree Frog (Hyla arenicolor).  How to tell it’s a frog? One way: no parotoid glands — instead you can see the round flat areas of its tympani (hearing structures) behind and slightly below the eye. Also, this frog has large adhesive pads on the ends of its toes to aid in climbing (after all it is a tree frog), which most toads don’t do.  Canyon tree frogs are variable in color and spottage (a technical term: feel free to pronounce it spot-AAHJ), but this individual is fairly pale and nearly spot-free. They inhabit rocky stream courses in Arizona and the Southwest with intermittent or permanent water, where they enjoy feeding upon small invertebrates. This one was photographed at Aravaipa Canyon. (Photo A.Shock, 2009)

Etymology

Hyla arenicolor: arenicolor is a Latin compound meaning sand-colored: to the Romans as well as to us, an arena is a sand-covered area.  The origin of the genus Hyla is a bit more complex, and much more picturesque.  To start, the greek work ὗλη — cognate with the more familiar Latin sylva, means woodland, and may come into play in the naming of a genus of tree frogs. But a more colorful tradition connects the genus name with Hylas, one of the original Argonauts who while searching for fresh water ashore was pulled into a woodland spring by a desirous water nymph.  Hylas’s companions — including Herakles and Jason — searched the island for him in vain, crying his name over and over: the story goes that the incessant cry of his name relates to the repetitive calling of tree frogs.

above: the story of the rape of Hylas, “Hylas and the Nymphs” by J.W. Waterhouse, 1896. If you’re lucky enough to be in London during the next couple of weeks, check out the exhibition: J.W.Waterhouse: The Modern Pre-Raphaelite, it’s on at the Royal Academy until 13 Sept 2009. (And, there’s a pleasing similarity between the color schemes of the Waterhouse painting and the tree frog photo at the top: the watery-brown background, ivory skin tones and heart-shaped green foliage.)

Everybody in the world has posted their version of the Miniature Watercolor Box, usually ingeniously created from any flat metal tin, often Altoids, sometimes Velamints, or others (see here, here, and here, just for a few examples of many).  These projects are all well-described and illustrated. I hereby add my version, but will only add a couple of tips I think are an improvement on what others have already shown.

As a hiker/backpacker, I’m always looking for a way to carry along sketching and watercolor or gouache supplies that doesn’t take up too much volume or weigh too much. (Or cost too much: commercially made ones are available at artist’s suppliers but seem exorbitant, if pretty cool.) Not all hikes yield usable painting or drawing time, and I want to carry something that I won’t begrudge space to if I don’t get around to using it. So I was enthralled by the mint-tin plein-air kits I saw on the Web.  It’s just the kind of project to seize my imagination, so off I went.  Which brings up the first tip: if this is your kind of project, beware taking up more time constructing your kits (or posting about them!) than painting with them — and I speak from experience — it’s easy to go there.  Although, the preparation can be big fun and have its own rewards.

The basic idea is to use empty, flat, metal boxes (such as those in the top photo in various stages of the process) to carry small containers (like contact lens cups, or polymer clay depressions, or purpose-made watercolor half-pans) filled with tube watercolors pre-squeezed out into them and allowed to dry.  The dried colors can be re-wet and used to paint, just like commercially available pan watercolors.  But with a customized mint-tin box, you can choose your own brands and colors, or easily switch them out for landscape, botanical, or portrait projects — whatever you like. (Second tip — don’t glue your pans permanently in place, as some folks recommend.  If they’re inconveniently loose, fasten them down with something temporary, like double-sided tape or that gummy product they sell; or, wedge them in with a bit of sponge or paper towel, which would be useful anyway for blotting. You want to be able to take them out to change or clean.)  Many people like to accompany these tiny paint-boxes with water-brushes like those made by Niji and Sakura, which have water reservoirs in their barrels, so they don’t have to carry extra water in a bottle. (The photo on the right shows the insides of boxes in various stages, the top one awaiting enameling, the other two enameled and awaiting paint selections.)

I don’t think I’m the only one who’s been saving metal Altoids tins for years with the idea that some day they’d come in handy.  Well, this is that day.  It turns out the older ones are best — the ones with the flat lids, without the product name embossed in the lid (like the one below on the left, painted with a red anti-rust primer).  The embossing is fancy, but since the inner lid becomes your mixing surface, a flat one is better (more about fixing that in a minute).

The inner lids of most brands are silver like the top one in the photo above — those are usable, but it’s easier to see your colors if you’re mixing on white. Some tins are already white inside. A few folks have inserted a portion of a plastic mixing tray here; good, but there’s both extra weight and extra work to cut it out of an existing watercolor palette (although you do get to wield your Dremel tool).  Others spray paint the surface white.  That’s the solution I went with, but here’s my next Valuable Tip: don’t just use white spray paint, use spray-on Appliance Enamel, found with the spray paints at hardware or DIY stores. It’s perfect — stain resistant, glossy, very white, quick drying, and rust proof.  It was miraculous to watch a metallic surface become pure white, shiny, and even in just 2-3 coats. I couldn’t stop using the stuff — the cats were lucky they didn’t end up slick and white.  Don’t forget to mask the outside with some tape before spraying.  If you want to obliterate the product labeling on the outside of your tin, use regular indoor-outdoor spray paint for that — I’ve been doing that after spraying the inside (mask it so that slick white surface isn’t contaminated).

Next tip, about indented lids: if you have an embossed tin lid, your mixing surface will have dents that cause color mixtures to pool.  If this bothers you, start by filling these dents on the inside of the lid with a waterproof product.  I use a modeling product called Apoxie Sculpt.  Just follow the instructions; you can smooth it out with a wet fingertip and then sand when dry.  Polymer clay would work as well, but needs to be oven-cured.  Remember to do your infilling before using the Appliance enamel.  This adds a level of complication to the project, both because of having to do the leveling and procuring the product, but I know your ingenuity is up to it.  If not, just forget it and find a non-embossed tin — they’re out there, but not Altoids, I don’t think — or, use the embossed lid anyway.  It’s not the end of the world. (The photo on the right, below, shows an embossed lid box filled and awaiting enameling, the other box is complete; it’s the rust-colored Altoids gum box above — you can see that the indentations of the lettering have been filled and the lid now has a smooth mixing surface).

Where to put the paints. Since I don’t wear contacts lenses and don’t have access to old lens cups, I was going to make my own half-pans with polymer clay to hold the paints, but I found I didn’t have the patience to make as many as I would need.  Using a solid pad of clay and making paint depressions in it is a good solution, but not for me: I wanted to be able to change out individual colors.  So I went for purpose-made plastic watercolor pans and half-pans, which wedge snugly into mint tins in various combinations.  Unfortunately, I found that individual empty pans are not easy to find, currently.  Jerry’s Artarama has them in their catalog, but as long as I’ve been working on the project, they’ve been out of stock.  I finally found another supplier, Natural Pigments, a cool vendor in Willetts, CA, who specializes in pigments and supplies for people making their own paints.  They have empty pans available for a good price, but frankly their shipping fees are mysteriously high for such lightweight items.  Still, beggars can’t be choosers, and that’s who I’ve been buying from.  Consider that another hot tip, with a caveat (shipping price).

Now you’re ready to configure your pans geometrically in your prepared tin, and select your palette — both tasks similar to scattering rice in front of a vampire: there are those who obsess on these things.  I won’t presume to dispense advice on color choice, but just a warning: the smaller the tin, the fewer your colors, the harder the choice, for most.

Let me finish off by saying that if this is the kind of project that floats your boat, there are many possibilities: different sizes of tins (to accommodate larger and smaller palettes); traveling tins for gouache (non-acrylic gouaches are re-wettable like watercolors and like them can be squeezed into pans and allowed to dry); and gifts for artist friends, with or without the paints (some artists are picky about their color choices).  Now that Altoids has introduced Smalls, there’s a Really Tiny Tin to challenge your minimalist palette selection.  And finally, modern mint-boxes are great, but how cool would vintage metal boxes be?!  I’m thinking Kiwi shoe polish, for one…

Yes, that’s “Cnemie-philia” — the love of lizards in the genus Cnemidophorus, now more properly called by their current genus name, Aspidoscelis, or Whiptails.  Our locals are Sonoran tiger whiptails (Aspidoscelis tigris punctilinealis), and they’re the most commonly seen lizard in our Phoenix area yard.  They like it hot and are out and about during the the day, except in the highest heat, constantly looking for prey such as insects and ants, which they are welcome to, as our ants have out-sized painful defense methods.  (Yet I love the ants, because they feed the flickers and the whiptails).  The young whiptails have been more in evidence recently, too — tiny whippety slippets of things, sleek and fast with brilliant blue tails that largely void their stripey camouflage against granite gravel.  Although the flashy and detachable nearly-neon blue tail might be an effective decoy for color-visioned predators, distracting them from more critical body parts.

Here’s a watercolor study of a tiger whiptail who, sadly, fell victim to the LaBrea Tarpit of our pool.  I finally took it out of the freezer drawer of our fridge, much to E’s relief, although there is still a Vaejovis scorpion chilling in there (this is when zip-lock bags really shine, I feel).  When I was through drawing, I took pictures and put the limp, thawed carcass out for a Curve-billed thrasher to find for a meal, but ashes to ashes: the ants found it first, bringing the lizard’s life full circle in a nutritional sense.

Etymology

Lately I’ve been slacking off on supplying etymologies for things, but this one’s already been covered, at the very bottom of the Desert iguana post, along with a swell photo by E of a (Plateau?) tiger whiptail we saw at the Grand Canyon.

On a completely unrelated and yet equally slinky-shiny note, if notes can be either slinky or shiny…

…are not a Victorian law firm.

They are delightfully specific bird-related terms: it seems that falconers and ornithologists, like the French, have a different word for everything.

You can talk about a raptor’s “thumb”, meaning the strong digit that in most birds is at the back of the foot, and people will know what you mean.  But there’s a useful Latin term for it, regularly and properly used in both falconry and ornithology: hallux, plural halluces.  Ornithologists have assigned birds’ toes numbers to express foot skeletal structure and toe arrangement, and the counting starts at the hallux: it’s 1.  Used in an informative sentence: “It’s useful to know that if you have a Great horned owl on the glove, and it’s gripped your free hand due to your inattention, ask someone to gently pull its hallux upward to release the grip, avoiding an unpleasant situation involving talons, pain and possible nerve damage.”  Actually, hallux is an anatomical term that refers to our own human big toe, too.  Any word with an X in it ought to be used as much as possible, says I.

That would include the word Retrix, which is a tail feather.  Plural: retrices.  Most birds have ten or twelve, and they are numbered in the order they are shed during a moult, which is from the center of the tail outward: R1 – R6, with the R1s being the two central tail feathers and the R6s being the two outer tail feathers.  Additionally, the two central tail feathers are referred to as the “deck feathers” or, as the French call them, les retrices centrales.  Used in a sentence: “The deck feathers are the first retrices to be moulted out of the tail.”  To learn more about feathers than you wanted to know, check out the Feather Atlas.  (Please remember it’s illegal to collect or own non-game bird feathers, by the way.)

Feak is a verb: feaking describes the action of a bird rubbing or wiping its beak on the perch or branch, usually for cleaning (the beak, not the branch).  Raptors do this after feeding to remove excess matter from the beak.  Songbirds do it as well, including hummingbirds whom I’ve seen feak after slurping at a nectar feeder.  It is a side-to-side motion, like sharpening a knife.  A raptor bends forward to feak, a hummingbird just tucks its chin.  Unlike the words hallux and retrix which are from the Latin, feak is an Anglo-Saxon word, and though it doesn’t have an X, needs to be said often, just to hear the sound it makes. Used in a sentence: “The Summer tanager should have feaked after eating that juicy katydid.” By the way, I think the French word for feak is feak, but I’m not positive.

Falconry is well-stocked with this and other specialist vocabulary, like stoop, warble and rouse, or yarak, haggard and crab — not to mention bate, creance and imp — each of which sounds like a Bleak House Dream Team.

The Eurasian Collared Dove (Streptopelia decaocto) has an agenda well-befitting a Columbid: “Must Colonize New World.”

Actually, it started before that, and a lot farther east: a native of central Asia, the Collared Dove had populated Europe as far west as Great Britain by the 1950s.  By the early ’80s, a population had taken hold in Florida, likely coming from the Bahamas where they also had been introduced (or escaped captivity) in the 1970s. From there, the large doves filled the southeastern US, and have been spreading inexorably west and north.  The first documented report of the species in the state of Arizona was in Eager, AZ, on March 6, 2000, and they were regularly sighted in Maricopa County by the end of the same year.

As mentioned in a previous post, they’re quite similar to the African Collared Dove (which used to be called the Ringed Turtle Dove), but they’re bigger, and a darker beige, and have different vocalizations.  In the Phoenix area and over much of Arizona, Eurasian Collared Doves have become quite numerous — on some days I would ungenerously call them a pest in our yard — and a few theories exist as to why they’ve spread so rapidly.  One is that they fill a niche left empty by the extinction of the Passenger Pigeon  (Perhaps in the Northeast U.S., but I’m not so sure that applies to the desert regions?).

Like the African Collared Doves, they show a disturbing willingness to become tame, and quickly learn  to fly down to empty feeders when they see someone coming out with a bag of birdseed.  I’ve caught them lurking on top of my studio — their toenails clicking on the roof, their pink foot skin glowing hazily through the translucent plexi panels — as if lobbying for the filling of neglected feeders in a kind of inexorable zombie-like way.  They’re hard to miss since their arrival is a dry noisy wing flapping, the thump of a hard landing of a big heavily-wingloaded airship, and the inevitable repetitive hoo-ing and gibbering that follows.

…was a Ruru, or Morepork (Ninox novaeseelandiae).

It’s NZ’s only remaining native owl (the Laughing owl was last recorded in 1914), and is fairly common in many habitats, even parks and gardens, but is especially numerous in tracts of native bush.  We heard them several places, mostly in the Kauri Forest while on a night walk looking for Kiwi.  They whinny and whoo and screek, but their main call is, not surprisingly, “More-pore” repeated frequently.  If you live where there are Inca Doves, you know what a Morepork sounds like.  Inca doves’ call is usually transcribed as “whirl-pool” or “no-hope”, but in pitch, frequency, and tone, it’s very much like the owl’s call.  The Māori name, Ruru, is also onomatopoetic, as is the Australian name, (Southern) Boobook.

Ruru is a relatively small (approx 10″ ht), long-tailed owl that takes a range of prey but specializes in nocturnal insects like weta (large crickets — really large crickets!), huhu beetles and moths.

As I mentioned previously, there are two pieces of mine in the NCECA “Potters as Sculptors; Sculptors as Potters” show currently up at Mesa Community College (see the Three Star Owl Events page for details).  One of them is the long-evolving “Toadstack” (the other is Venomosity which can currently be viewed on the Home page.) As promised, here is the entire Toadstack story in pictures, culminating in the final state of the piece.  They go from L to R and Top to Bottom; don’t forget you can click on an image to enlarge it:

and the finished piece, Stacked Toad Teapot Effigy (Toadlier than Teapotly):

This show is associated with the annual NCECA (National Council on Education for the Ceramic Arts) Convention, which opens in town tomorrow (Wed 8 April).  From now until Saturday, Phoenix will be popping with potters, sculptors, and ceramic arts educators.  The downtown Phoenix Convention Center is the main venue, where the discussions, demos, lectures, and exhibitors will be located.  There’s a fee to attend that part of the conference, but there are many many galleries, museums and other display venues which have shows up featuring the work of both nationally known and local clay artists, and these shows are FREE AND OPEN TO THE PUBLIC.

So if you like looking at the broad range of contemporary ceramic artwork and what’s being made in America today in clay, check out the NCECA website for lists of and maps to the concurrent shows and outlying venues which are all over the metro area.  Principal show clusters are located in Tempe, in and around the ASU Campus; Mesa, at both the Community College and the Arts Center; downtown Phoenix in the hotels around the Convention Center; and Scottsdale, in the Old Town Arts District, a fun and stimulating place to visit anyway.  It’s a great time in Phoenix to Get Out and See Art.

One more post from our desert hike last weekend, because, well — Wow!

Right along the trail we encountered two specimens of individual cactus that seemed taller than most of their kin.  One was a towering, somewhat spindly saguaro. Of course, saguaros are known for their height, but this was one of the tallest I’ve seen personally.  Here’s a shot looking up at its crowns from the base. I’ve also included a picture of the saguaro with E, who is just over 6 feet tall.  If you figure you could stack about 7 of him to the top of the cactus, it’s probably close to 45 feet tall which is about maximum species height.  Maricopa County is the home of one of the state’s champion saguaros which is just over 50 feet in height, but it grows somewhere in Scottsdale.  By the way, although this saguaro has probably survived brush fires, the blackened, tough-looking skin on its lower section is more likely bark, developed with age, in place of the smooth green skin we’re used to seeing on younger individuals.  When the skin becomes calloused and barky, the spines are no longer as needed for protection against gnawing animals, and they gradually become the vestigial, button-like bumps you can see in the photo above.

The other picture also has E for scale, but that’s not a young saguaro he’s standing next to.  It’s a barrel cactus: a compass barrel, Ferocactus cylindraceus, one of the most commonly encountered barrel cactus in this part of the desert.  They’re big barrels, and when you come across an undisturbed cluster of elderly ones, they’re often 4′ to 5′ tall. But this one, with two small ones growing at its base — probably its own seedlings from many seasons past — looks to be more than 8 feet tall, which must approach the maximum height of the species.  The only barrel cactus I’ve seen to compete are the famously tall Diguet’s barrels (Ferocactus diguetii) which can reach 4 meters in height. They grow on just a few islands in the Sea of Cortez off the eastern shore of Baja California.  Below is a photo of one, but it’s only of average height — no more than 7 feet. And check out the tiny tiny bud of a baby barrel coming up at its base: it looks like a tennis ball. How cute is a baby cactus ?

All photos A. Shock (except Diguet’s barrel on Santa Catalina Island, by E. Shock), and with no camera tricks, like standing farther from the camera than the subject: no Hogzilla here!

Here are a couple of photos that show two excellent see-through specializations of Turkey vulturedom: the pervious nostril (already discussed here) and an inner protective eyelid called the nictitating membrane. The camera caught the vulture in mid-blink, so the membrane is visible in this photo as a bluish milky cast over the eye of the vulture – if you click to enlarge the photo to the left, you can easily see it, including the leading edge of the inner eyelid, which slides closed toward the back of the eye. Notice that you can faintly see the bird’s pupil through the membrane: if you can see it, it can see you (like a truck-driver’s rear-view mirror). The lower photo shows the membrane fully closed, and the vulture apparently looking through it at something to the left. (Top photo A. Shock; bottom photo E. Shock)

Most birds have a nictitating membrane (as well as some other animals, like manatees and horned lizards), and in every animal it has the same basic function — to provide a see-through protective lens over the eye which can be deployed during high-risk activities, such as rummaging through a ripe porcupine carcass with a couple of sharp-beaked buddies (in the case of vultures); plunging into a thorny mesquite bosque in pursuit of a road runner (Harris’s hawk); stooping at 100 mph after a mid-air dove (Peregrine falcon); digging in sandy soils, then cleaning and moistening the gritty cornea (horned lizard).

Brief etymology: “nictitating” is derived from Latin nictare, to blink.

HEN UPDATE: The Hen is still tight-on-Nid, having weathered yesterday’s quite breezy atmosphere.
