Fast Food

When humans talk about making a breakfast, lunch, or dinner run, it’s understood that we’re speaking metaphorically. Truth be told, we’ll probably drive, not jog, to a local café, convenience store, or Kroger. The same cannot be said about the way greater roadrunners (Geococcyx californianus) grab a meal. Fast food is how these long-legged, long-tailed, long-necked North American cuckoos roll—make that sprint—through life.

I mean that quite literally. Roadrunners are feeble fliers but they can definitely beat feet. Angling the body forward to nearly parallel with the ground as they pick up speed, the tail is held flat, acting as a stabilizer during turns. Their unmistakable X-shaped feet, with two toes pointing forward and two toes pointing backwards, are better suited to life on the run than the typical three-one toe formation of perching bird species. And who needs powerful wings when you can leap skyward, as if propelled by a pogo stick, to grab a snack out of thin air?

If you grew up in the U.S. during the latter half of the 20th century, as I did, you may have some serious misconceptions about this fleet-footed bird, not to mention coyotes (Canis latrans). For example, roadrunners are quick but at top speeds of 43 mph, coyotes are more than twice as fast. Smarter, too.

Moreover, I think Warner Brothers animator Chuck Jones must have grabbed the wrong field guide when he started to sketch, because his roadrunner looks more like an ostrich (Struthio camelus) to me than the iconic avian of the American Southwest. I think you’ll agree that a side-by-side line-up provides plenty of evidence to back up that statement.

Roadrunners do have at least one thing in common with ostriches—both birds prefer more arid, savannah-like landscapes to damp, dense forests. That said, greater roadrunners have been expanding their range, moving east from southern California, Arizona, New Mexico, and Texas, into the juniper, pine, and hardwood stands of Oklahoma, Missouri, Arkansas, and even Louisiana. And while they won’t tolerate densely populated urban areas they are showing up in more open suburban developments.

Like so many desert species, roadrunners have evolved to survive in a low rainfall environment. This includes a gland near each eye that secretes a highly concentrated salt solution, reducing the amount of water lost through their urinary tract. The ability to efficiently use the moisture present in their food reduces the roadrunners’ dependence on scarce surface water supplies.

I have a few more bones to pick with Warner Brothers’ depiction of the life and times of coyotes and roadrunners. For one thing, those cartoon characters would have you believe one is a predator, the other prey. Well, my friends, that’s as wrong-headed as expecting a tiny Acme parasol to protect you from a falling boulder.

The real skinny is that roadrunners are predators, too. Their moveable feast includes just about anything they can catch, including insects, spiders, scorpions, frogs, toads, songbirds, bats, rodents, and lizards. They’ll even pair up to take on a rattlesnake—one bird distracting the serpent, the other sneaking up from behind to pin the head down, rending those venom-delivering fangs moot.

This chick is all business. I’m not kidding.

Once their prey has been dispatched, roadrunners swallow their food whole, so there’s no need to carry around silverware, a la Wile E. Before that hummingbird goes down the hatch, though, there’s an important food prep step that has to take place. Fair warning—the process will make you reconsider the sincerity of that two-dimensional speedster’s goofy grin. I’ll let my friend, fellow wildlife enthusiast, and long-time Albuquerque resident, Janelle Harden, deliver the play-by-play:

“Not everyone would appreciate this, but I know you will! I saw a roadrunner catch a house finch on my driveway the other day. Holding the dead bird by the head, the roadrunner proceeded to bash and thrash the carcass against the concrete curb. Once the skeleton was pulverized and the body limp as an al dente noodle, the roadrunner threw her head in the air, along with the finch, opened her bill, and let gravity do its thing. It was fascinating! Took about 6-8 big swallows, and I swear her eyes got bigger with every gulp!”

I have to admit, I do appreciate Janelle’s field observations, and her description of the roadrunner’s bulging eyes does sounds pretty cartoonish. It’s the kind of thing I could imagine happening to a certain famously incompetent but persistent wild canid. Maybe Chuck Jones wasn’t a total Looney Tunes after all.

Gotta run—that’s all, folks!

Wingsuit

Southern flying squirrel (Glaucomys volans), © 2014 Peter Harrill, used with permission

Is there any non-human skill people covet more passionately than the ability to fly?

Understandably, early aviation experiments centered around mimicry of birds, complete with flapping arms that were usually covered in feathers. The Greek legend of Daedalus and Icarus is a familiar example, but plumage continued to be part of the trial-and-error approach through the first years of the 19th century, when a tailor named Albrecht Berblinger constructed an ornithopter and then took an ill-fated plunge into the Danube. Those daring young men with their dreams of flying machines… they just didn’t understand the concepts of thrust, lift, and drag, and they couldn’t let go of the idea that soaring requires feathers.

I guess Saturday mornings with Rocky and Bullwinkle were not a part of their childhood.

Skip ahead in the history books about two hundred years, during which heavier-than-air flight went from foolish fantasy to fleetingly airborne, to semi-reliably aloft, to acrobatic enough to decide the outcome of a World War, to commonplace as ~30,000 commercial flights per day in the U.S. in 2017.

And yet…

Aviation advancements and inventions during the greater part of the industrial age were about balloons and dirigibles and planes, i.e., aircraft; human beings remained firmly planted on terra firma unless they could climb inside or hang from some kind of apparatus.

It’s hard to point to a specific aeronautic adventurer as the first to see a flying squirrel, recognized the similarities with their fellow mammal, connected the dots, and think, “Eureka! A wingsuit!” But no one lucky enough to have seen one of these big-eyed nocturnal windsurfers could fail to notice the resemblance to the modern flying suits that have finally allowed human beings to fly free as a bird squirrel, unencumbered by gondola, scaffolding, or fuselage.

Of course, strictly speaking flying squirrels don’t really fly, and neither do the people wearing a wingsuit.

They glide.

The wingsuit mimics a flying squirrel’s patagium—loose folds of skin that span the space between forelimb wrist and hindlimb ankle on either side of the body. Spreading those limbs into a jumping jack X, the furry membranes stretch into a rectangular shape that allows the tiny BASE* jumpers to propel themselves into the air and then slide down the sky at a 30-40 degree angle controlled fall.

A long, flat tail is critical for controlling that fall. Serving as a rudder, it allowing 90 degree turns around mid-flight obstacles. The tail is used for landing, too; on the approach, the tail is raised to an upright position while, at the same time, all four limbs move forward to form a kind of patagium parachute. Together, these actions create enough drag to tip the animal’s head and body up as it prepares for impact with a tree trunk or branches, a bird feeder, or a building.

Northern flying squirrel (Glaucomys sabrinus) © 2015 Jukka Jantunen, used with permission

The New World is home to three species of rodent flyboys and flygirls: Northern (Glaucomys sabrinus); the recently differentiated and designated Humboldt’s (G oregonensis); and Southern (G volans). There’s some range overlap between Northerns and Southerns, but the two species are relatively easy to distinguish. Northerns are larger, but the belly of the beasts provides a much more notable difference; the underside of a Southern flying squirrel is creamy white, while Northern flying squirrels are beige below with darker roots.

Humboldt’s flying squirrel

There’s range overlap between Northerns (found from Alaska to Nova Scotia down to Utah and North Carolina) and Humboldts’ (whose limit their travels from British Columbia down into southern California) as well. However, the two are close enough in physical appearance and behavior that it took an examination of their DNA before scientists realized earlier this year (May 2017) that they were looking at not one species, but two. Humboldts’ have been described as smaller and darker than Northerns, but the fact that it took so long for the former to be recognized as distinctive (Southerns were first described in 1758, Northerns in 1801) suggests to me that one would have to do a mighty up-close-and-personal examination to make a positive ID.

All three varieties of Glaucomys have one important feature in common: they’re more risk-averse than you might have assumed. Riding the wind wearing a wingsuit is a dangerous activity for humans — one severe injury for every 500 jumps, according to one study, despite advances in materials, design, and training — but it’s just another day in the life of a flying squirrel. That’s not to imply they never miscalculate a distance, or botch a landing, or are immune from injury (or worse), but they do have concerns beyond thrust, lift, and drag, or changes in wind speed and direction.

Which is why, immediately after sticking the landing, a flying squirrel will scurry quickly to their nest hole, or the other side of the tree, or at least toward a deeper shadow. BASE jumpers and skydivers rarely have worry about avoiding predators waiting in the wings.

*BASE is the acronym that stands for the four categories of fixed objects from which one can jump: building, antenna, span (bridge), and Earth (cliffs).

Long-stemmed

Daddy longlegs are the jazz cats of the arachnid world!

This realization came to me as I watched a single backlit note poised on a broken music staff bebop across the asphalt path in front of me. A soundtrack of jazz piano greats immediately began to play in my head — Willie “The Lion” Smith, Thomas “Fats” Waller, Art Tatum, Thelonious Monk, and Dave Brubeck, to name but a few. Chill dudes whose spider-like fingers strode, slid, bounced, and stomped across the keys.

Jazz has evolved and diverged from it’s start in the late 19th century as  ragtime and Dixieland into a genre so diverse it can be difficult to define, or even to list all the variations: Swing, Cool, West Coast, Modal, Free, Fusion, Funk, Cu-Bop, Post-Bop, etc.

The harvestmen, as daddy longlegs are also known (that even sounds like a 1950s jazz band, doesn’t it?) have an even longer and more impressive history. They’re a vast, improvisational set that spans millions of years and many taxonomic octaves, with over 6,500 named species worldwide (experts estimate there may actually be more than 10,000). And while not all the players in this big band have long legs, the ones who hangout in my neighborhood— eastern harvestmen (Leiobunum vittatum)— are definitely long-stemmed.

These invertebrate daddy-o’s are arachnids but they are NOT spiders; they’re more closely related to mites and scorpions.  Harvestmen don’t have a spider’s tiny waist… or venom… or silk (so no webs)… and they have only two eyes instead of eight.

Jazz musicians need to maintain their instruments to get the best sound; piano hammers need to be voiced, strings tuned, reeds moistened and valves lubricated.  Daddy longlegs are similarly serious about the tools of their trade, cleaning each leg after a meal by threading them through the pincers by their mouths.

Harvestmen are a gregarious lot who periodically congregate in the hundreds or even thousands. Scientists have suggested these spontaneous jam sessions might occur in response to climatic conditions or provide some protection against predators… but it’s pretty clear they aren’t making music (that can be detected by the human ear, anyway).

Members of Order Opiliones are exceptional even among arachnids. They can swallow small pieces of solid food, whereas their cousins are limited to a liquid diet. Conversely, daddy longlegs sip oxygen through their legs into a trachea, while other arachnids respirate through a gas exchange organ called a book lung. That’s probably just a warm-up, though. Like jazz, daddy longlegs are both familiar and mysterious. Little research has been done on these species… and who can say why? Maybe they’re a bit too avant garde to have a large fan base among researchers.

Or it could be the hours they keep and the dives they frequent. See, eastern harvestmen have more in common with jazz pianists than an impressive hand (or leg) span. Say what you will about the pleasures of sitting outside at a warm summer evening festival, lounging on a blanket in the grass while listening to a live performance — you’ll hear no argument from me. But to my mind, jazz is an urban art form, and the smokin’ hot licks happen in basement clubs. An intimate corner, low lights, insulated from street noise, maybe just a little damp…

Now that the kind of gig daddy longlegs’ dig.

Vert-de-Gris

It isn’t easy being green. Kermit the Frog said it, so you know it has to be true.

He’s always seemed a reluctant celebrity, so my guess is that being the most famous Muppet-amphibian on the planet isn’t always a picnic. I wonder whether life would be a little less stressful if, like some of his cousins, Kermit could change from green to another color when he’d rather not be so conspicuous.

North American gray treefrogs know how to be seen and when to blend into their surrounding, shifting the spectrum from bright emerald to peridot, to gold, copper, platinum, silver, and even gunmetal. Since the places they hang out — trees and shrubs in woodlands, meadows, prairies, swamps, suburbs, and cities — tend toward palettes awash with green and gray hues, these arboreal amphibians can keep their sartorial choices simple. 

What looks like a costume change is actually a rather high-tech, cellular-level special effect created by chromatophores. These pigment-containing and light-reflecting cells, or groups of cells, are present in the skin of certain frogs, as well as some reptiles (including chameleons), cephalopods (such as octopi), fish, and crustaceans. Mammals and birds, on the other hand, have melanocytes, a different class of cells for coloration.

Chromatophores are classified based on their hue under white light:

  • melanophores (black/brown)
  • cyanophores (blue)
  • erythrophores (red)
  • xanthophores (yellow)
  • leucophores (white)
  • iridophores (reflective or iridescent)

The process, known as physiological color change, can be controlled by hormones, neurons, or both. Most studies have focused primarily on melanophores because they are the darkest and, therefore, the most visible. When pigment inside the chromatophores disperses throughout cell the skin appears to darken; when pigment aggregates in cells the skin appears to lighten. Either way, you’ve got an amazing makeover, or a convincing disguise, in no time flat! 

There’s even more to the gray treefrog’s ability to assume an alter-ego than meets the eye —what appears to be a single species is actually two very close relatives: Hyla versicolor, aka Eastern, although there’s a long list of pseudonyms from which to choose (there are more ways to hide than blending into the substrate); and Hyla chrysoscelis, aka Cope’s (which also has a couple of nicknames but not as many as H. versicolor).

Cope’s and Eastern are equally skilled at clinging to and climbing slick surfaces using large toe pads that secrete mucous, creating surface tension. It’s not uncommon to find one plastered against a window pane (allowing for an interesting view of their nether-regions). Both species prefer a diet of small insects, spiders, and snails. Both hibernate under leaves, bark, or rocks. Well, “hibernate” sounds a lot more cozy than the reality… which is that their bodies pretty much freeze and their lungs, heart, brain, and other organs stop working until they thaw out and reanimate in the spring. It’s a pretty nifty chemical trick, on par with being able to transform your complexion at will. 

Kermit has an unmistakable personal brand, but distinguishing H. versicolor from H. chrysocelis visually is just about impossible. Both Eastern and Cope’s are relatively small (1.5—2.0 in/3.5—5 cm), and the adults are often mistaken for younglings. Both wear a sweep of bright citrus-orange along the inseam of their hind legs (a signature shade is all the rage, you know).  Females of both species are usually (but not always) larger, with a ladylike white throat. During the breeding season, males have a macho (make that hipster, since it resembles a beard) black, gray, or brown throat. Guys sing. Gals swoon, but don’t sing along.

The ranges of these two species overlap, but Cope’s are more widely distributed. If you find a gray treefrog in North Carolina or Georgia, you can be reasonably certain it’s a Cope’s, but if you’re in Iowa or Pennsylvania, all bets are off. The only risk-free way to know for sure is to do a DNA test — Cope’s are a diploid species, meaning they have two sets of chromosomes, one from each parent (for a total of 24); Easterns are a tetraploid species, meaning they have four sets of chromosomes (for a total of 48).

Now, some frog call connoisseurs claim they can detect variations in breeding calls, and that Cope’s treefrogs have a faster and slightly higher-pitched trill than Easterns. But the call rates of both species change with ambient temperature… so color me skeptical.

[Postscript:  What kind of frog is Kermit? While I’ve never found a definitive answer to this question, I always assumed that because he was created/discovered by Jim Henson, he was probably Hyla muppetalis or Rana hensonii… something like that. However, in 2015 Brian Kubicki of the Costa Rican Amphibian Research Center discovered a frog who, if not the same species, must at least be a first cousin, or possibly Kermit’s doppleganger.]

Virtuosity

Maybe Bobby McFerrin was a house wren (Troglodytes aedon) in a previous life.

This thought popped into my mind when, after listening to On Being’s Krista Tippett interview the singer, I went out for a walk with my canine companion. We hadn’t made it too far down the sunny trail when we were suddenly drenched by a deluge of liquid notes. That vocal tsunami, pouring forth from an entirely disproportional feathered Dixie cup, stopped me in my tracks.

Like McFerrin, who is known for fluid, polyphonic singing and quick, oceanic octave jumps, the wren’s song bounced around like raindrops on pavement. I suppose that’s why the synapses in my brain connected the two muscians.

There are definite differences between these gifted songbirds, though.

For example, wrens and other passerine birds produce vocal sounds using an organ called the syrinx, positioned where the trachea splits into two bronchial tubes. Each side of the syrinx operates independently, so songbirds can produce a sweeping range of notes in fractions of a second, or two different pitches at the same time, or simultaneous rising and falling notes, all without stopping for a breath. Humans, by contrast, make vocal sounds by sending air from the lung into the windpipe, through folds (aka vocal cords) in the larynx, and out to the throat, nose, and mouth.

Admittedly, McFerrin often sounds as if he has a syrinx but, hard as it is to believe, he’s making all of those notes with the same equipment you and I have. It’s just that he’s playing every instrument in the orchestra, and we’re barely pecking out “Chopsticks.” His ability to switch pitch is inarguably stunning; however, even this virtuoso can’t match the speed of a wren running through the scales.

McFerrin has a rich and ever-expanding repertoire that includes pop, a capella, choralclassical, spirituals, and movie scores. Like any jazz artist worthy of the title, he is a master of improvisation; always learning, always expanding his technique, consistently creative and ready to try something new. Wrens, on the other hand, may sound like they’re jamming but they’re actually shuffling 12-16 stock syllables… kind of like a classically trained musician who learned to play according to the rules of the conservatory but wants to sound cool enough to swing.

You see, passerines begin their musical education when they are barely out of the egg, during a development phase known as the critical period. Listening to the adult birds around them, the youngsters tune in to the songs and calls of their own species. Once young wrens have left the nest they practice, over and over and over, dialing in the sounds until the song matches the memory. With the exception of mimicking species (e.g., mockingbirds, catbirds, and thrashers), there will be no extemporization. That’s because wrens choose a mate based on the ability to cover “their song” note for note. Some bird songs have geographic variations, sort of like regional accents, but chicks want a boy who sounds like he’s from the neighborhood, and will pass over anyone who sounds too exotic or experimental.

I’m much less discriminating, at least on that score. Bubbling, effervescent singing, whether it’s an improv by McFerrin or a house wren standard, always helps me tune out my worries… and that makes me happy.

[Play both videos at once so Bobby and the house wren can duet!]

Lonesome Doves

It’s a fine world, though rich in hardships at times. ~ Larry McMurtry

There’s a sweetness in the lament of a mourning dove (Zenaida macroura) that makes the sorrow bearable, and believable. Theirs isn’t an pop tune about a hookup with a hook, or a power ballad tale of infatuation, thrill, and transitory heartbreak. When mourning doves call I hear a country-western melody about spacious, isolated landscapes and complicated lives composed of joy and calamity, love and betrayal, not to mention good and evil that can’t be easily differentiated by the color of someone’s hat.

Country music has had it’s share of singers who could wail with convincing anguish on stage, then party ’til the cows came home once the show was over… so I have to wonder if the mourning dove’s high lonesome yodel —coo-OO, COO, coo — is simply part of the act. After all, that grievous angel cry is replaced by a jaunty whistle of wings every time they launch skyward.

Plus, doves are rarely alone and don’t seem to have much time in their lives to feel lonely. The whole clan is known to grow up fast (reaching sexual maturity at about 85 days old) and then pair up into monogamous ’til-death-do-we-part couples who take the directive to be fruitful and multiply seriously… as in up to twelve chicks in a single season serious (six broods of two chicks each). Both Mom and Dad are doting, active parents who share grocery shopping and child care equally, rarely leaving their babes unsupervised by at least one adult at all times.

The end of the lovey-dovey breeding season shouldn’t bring on the lonesome blues either, because that’s when the community flocks together in a big way. They go on group picnics, gobbling up seed in open fields or from the ground beneath backyard feeders until their crops are full, then settle onto fences, or walls, or telephone wires to digest the meal and the days events. They go drinking together, although for doves that means sipping water from puddles and bird baths rather than throwing back with Jose Quervo at the neighborhood saloon.

The community even sleeps together— literally, not euphemistically — roosting in trees and other protected areas. Comforted by the safety of numbers, they’ll drop their heads comfortably between raised shoulders rather than tucking in beneath a wing or over the back as so many other birds do.

Despite all the social network support, there is a darker side to the life of a mourning dove that may explain their doleful song — they often end up on the wrong end of a gun. Mourning doves are abundant, with a population estimated to be comprised of nearly 500 million individuals, but they are classified as a game bird and are the most frequently hunted species in North America. As many as 70 million are shot by hunters each year. Those who dodge the bullet still have to contend with the threat of lead poisoning from shot picked up from the ground while feeding.

Despite what their name implies, though, when one of these doves becomes a widow or widower they don’t spend a lot of time in Brokenheartsville bemoaning their newly-single status. In fact, they pair up again pdq. After all, ya can’t be fruitful all by your lonesome.

Spotted!

A spotted towhee caught on a fast-food run, and not particularly happy about it.

Supermarket tabloids love just-like-us features so they pay paparazzi top dollar to catch somebodies acting like nobodies. Today I’m focused on the Towhees. They like to keep a low profile but I’m a pro and I know how to find them.

First Rule of Papping: Ya can’t tell the players without a scorecard! It also helps to know the aliases they use to create confusion and avoid detection. See, for a long time all the Towhee’s identified as Team Pipilo. Several years ago, however, about half of them left (were removed, actually) to form Team Melozone. Maybe the rift was media-created (fake news, so sad), or maybe the less flamboyant Towhees felt overshadowed by their more colorful and fashion-forward cousins… who knows? Towheestas, as their fandom are known, love to argue over the distinctions between and relative merits of the two tribes, as well as who should be a P and who definitely qualifies as an M.

Currently,  Team P include the Collareds (P. ocai),  the Green-taileds (P. chlorurus), the Easterns (P. erythrophthalmus), and the Spotteds (P. maculatus), but not so long ago both the Easterns and Spotteds were using the tag Rufous-sided (the Easterns got full custody of P. erythrophthalmus). Spotteds are also referred to in some circles as The Avians Formerly Known as Oregon or Socorro.

Similarly, and to keep things even-steven, Team M also has four members: the Aberts’ (M. aberti), the White-throateds (M. leucotis), the Canyons (M. fusca), and the Californias (M. Crissalis). Oh, but the Canyons and the Californias used to be one big happy tribe, the Browns, even though the Aberts’ and the Californias are probably closer relatives.

Got it all straight? Yeah, it’s a complicated family tree — that’s show biz. Try keeping track of the rest of the Sparrows, not to mention the Barrymores, the Fondas, and the Coppolas.

Second Rule of Papping:  Zoom in on the habitat. Finding out where your luminary lives is a crucial datapoint.  Some Towhees prefer to be on the right side of the continent (Easterns), some are Westerners (Californias, Green-taileds, and Spotteds), and there’s some who meet in the middle. Others Towhees prefer the Southwest (Canyons and Aberts’), or even south of the border in Mexico (Collareds & White-throateds).

Towhees do household chores, just like us!

When it comes to choosing a home base, the Easterns and Spotteds will always opt for a ground-floor unit, if available, ideally tucked in next to a log or of clump of grass to provide some privacy, but they’ll tolerate the higher perches (shrubs) preferred by the Californias, Canyons, and Green-taileds. The Aberts’ are the only Towhees who like to live in a tree-top high-rise. Not much is know about where the Collareds and White-throateds homestead because they’re a secretive bunch who’ve put down roots far from the limelight’s glare, in the more rural setting of Mexico’s mid-to-high altitude subtropical and tropical pine-oak forests. They’re a rare and lucrative shot but too remote for run-and-gun photography.

A Spotted spotted at the spa.

Improve your chances by becoming a regular at all of the places your subjects like to eat, including the local hipster farmers markets and upscale grocers, where they shop for household supplies, as well as favorite watering holes and spas. If you can get a neighborhood exposure you’re golden because that’s where life gets real. As the playground K-I-S-S-I-N-G song tells it, first comes love, then comes marriage, then comes baby in a $700 Bugaboo carriage. Actually, these days marriage is an option, not a certainty. Regardless of the parents’ living arrangements and legal status, or lack thereof, nest/crib beta is pivotal for a paparazzo because editors drool when there are kids in the picture — Mommy & Me outings are always Money Shots.

A California towhee takes her mini-me out for lunch.

Third Rule of Papping:  Know your subject inside as well as out. In other words, not just their look but the idiosyncratic behaviors that will tip you off to their presence, even when they’re not wearing breeding plumage. For example, you’ll want to know that all the Towhees like to forage for food using a unique two-footed backward hop, followed by a pert bend-and-snap. Well, I assume this includes those camera-shy Collared and White-throateds but who the hell knows. If the pickin’ are slim, or maybe too predictable, Spotteds will scan the shrubbery for snacks, and the Aberts’ have been known to poke around under the bark near the bottom of tree trunks for some grub.

Family comes first for the Canyons and Green-taileds, who have a reputation for forming long-term, monogamous pair-bonds. If a Green-tailed mom senses danger, she’ll bravely flee from home on foot with a conspicuously raised tail to attract and distract the predator’s attention from her children.

A California fascinated with its reflection in a window.

It will probably come as no surprise, that the Cali Crew has an ongoing love/hate relationship with their image — you’ll see them in front of a freshly washed window, handy car mirror, or any other reflective surface checking out their visuals or talking to themselves in a very critical, territorial tone. They’re not crazy, just a little left of center. They like to chill in stands of poison oak, feeling all cutting edge because this hangout hasn’t been “discovered” yet, gobbling up the pale berries as if they were caviar.

Last, but not least… shut up and get the shot. Sure, the relationship between some celebrities and the paparazzi is symbiotic— they get publicity, you get residuals. Towhees don’t play that. If you want to be successful with this dynasty you’ll stay quiet, blend into the scenery, keep your eyes open, and your finger on the trigger. Be the early bird that catches the worm. Not that Towhees are worms. Far from it. Truth is, they’ll eat that worm for breakfast… and you could get it all on film (or a memory card).

Slender in the Grass

[photo: josh more, ccl]

But never met this Fellow, Attended or alone, Without a tighter Breathing, and Zero at the Bone.

 

Unlike Emily Dickinson, ophiophobia isn’t an issue for me. I like snakes and know them to be upstanding ecosystem citizens… umm, ok, upstanding probably isn’t the best descriptor for creatures without legs but you get my drift.

Of course, I offer an extra measure of obeisance for any and all animals who engage in chemical warfare but their numbers are relatively few here in North America. Of the over 125 snake species endemic to my home continent, for example, only 21 are venomous. All 18 of the vipers have a distinctive triangular head, and the 16 rattlesnakes in this group are armed with an unmistakable warning system. The 2 coral snakes species found in the U.S. wear a color pattern that’s easy to recognize from further than arm’s-length, and since Blacksburg, Virginia, isn’t anywhere near the western coast of Mexico I don’t have to watch out for yellowbelly sea snakes.

So if I happen upon a small garden hose that unexpectedly untangles and slips into the lawn I’m not chilled to the marrow. On the contrary — when I spot a green grass snake (Opheodrys spp.) passing by I’m likely to lean in cordially and say, “Well, hello gorgeous!”

And what comely creatures these colubrids are, with large, round eyes and a red tongue tipped in black.  Bright, nearly neon green above, accented with sunny yellow and ivory below, their color scheme is positively tropical despite the fact that they’re only found well above the equator.  Both the smooth (O. vernalis) and rough (O. aestivus) are slight and lithe. For this genus “rough” refers raised scale keels along the back and sides but, like all snakes, the skin of both grass snake species is satiny, not slimy.

Contrary to what the name implies, grass snakes don’t limit themselves to turf and terra firma. They are great climbers, moving with grace and prudence as they stalk insects and small amphibians through brambles, bushes, and trees. The many regional names given to this species testify to this fact, including: magnolia snake, huckleberry snake, vine snake, bush snake, and green tree snake. Grass snakes are also known to mimic small breeze-blown branches to blend into the surroundings while waiting for prey, or while attempting to avoid becoming prey to birds, mammals, and other snakes, including the eastern racer (Coluber constrictor) and the eastern king snake (Lampropeltis getula).

Grass snakes are good swimmers who are often found near water, in and around moist meadows and marshes, in riparian habitat as well as open forests and woodlands, as well as cities and suburbs.

Their willingness to live in developed areas puts grass snakes at risk of being persecuted by house cats, run over by cars and mowers, and they appear to be susceptible to pesticides as well.  These docile beauties haven’t gone unnoticed by the pet trade, sadly. Although Smooths are protected in some places, few states in the U.S. regulate reptile harvest.  Hundreds, perhaps thousands, of grass snakes are collected from the wild each year, making them one of North America’s most exploited snakes. This practice is particularly tough on Roughs because they are easily stressed and don’t do well in captivity.

Seems to me Emily’s reaction to spotting a snake is more appropriate and understandable from that narrow fellow’s point of view… don’t you?
