A Snake’s Worst Nightmare, Beautiful Autumnal Creatures, and Lightning far too Close for Comfort – Again!

The snake pictured above is a black-tailed rattlesnake, Crotalus molossus. Of the nine species of rattlesnakes inhabiting Cochise County in southeastern Arizona, this one is my favorite. (If you don’t see the image, it is because you are reading this in your email. Click on the blog’s title to be redirected to my blog website for a better, more inclusive experience.

If snakes could talk, when asked the question “what is hell?,” they would likely answer “any place where people are.” Many people kill snakes on sight, and others run them over with vehicles – often a brutal, intentional action. If snakes have dreams, surely one of their worst nightmares would involve becoming entangled in certain types of fencing, like chicken wire or plastic mesh. A snake can slip its head through the openings in these kinds of fencing easily. The trouble comes as the reptile moves forward. As the body thickens behind the neck, there comes a point when the snake becomes trapped. Scales on snakes overlap and point backward. The wire or plastic mesh gets caught under the scales, making it impossible for the snake to back out. A long, slow death is the inevitable outcome. I have seen live and dead snakes trapped in fencing more than a few times, especially in chicken wire and in various types of plastic mesh and bird netting. The bottom line is simple: if you care about snakes, don’t use these types of fencing! Find another way.

Late this summer, a neighbor called requesting my help to free this 4-foot Sonoran whipsnake, (Masticophis bilineatus). The snake was badly entangled in some plastic mesh fencing. It took quite some time with a pair of small scissors to free the snake. This feisty whipsnake tried to bite me repeatedly during the delicate procedure.

Sonoran whipsnakes are among the desert’s most beautiful reptiles. They are capable of incredibly fast movements much like their cousins, the coachwhips. Large, capable eyes give this creature excellent long-range vision for hunting its prey and avoiding predators. These snakes are semi-arboreal, often found high in the mesquite trees, where they move with skilled grace in search of lizards and bird nests. This one had skin that felt like fine silk, remarkably smooth to the touch.

October brought this 3-foot Sonoran gopher snake to our residence. I have never seen gopher snakes as richly colored as the individuals I have encountered in this river valley. They are Arizona’s longest ophidians, (reaching lengths exceeding eight feet) and they are always more than welcome here. Few predators are more adept at capturing mice, rats, and pocket gophers, for these animals can do what most other predators cannot – they can crawl down into the rodents’ burrows.

Nowhere else have I seen box turtles as gorgeously marked as our local variety. This is an adult – some of these turtles lose their stripes, fading to a solid brown as they get older, but not this one. The species is Terapene ornata, otherwise known as the ornate box turtle.

Yet another Gila monster visited our property this year. This one was an adult measuring close to 14 inches in length. These lizards are readily identifiable as distinct individuals, for their complex markings are never the same, somewhat like our fingerprints.

The track of an opossum may be a common sight east of the Mississippi, but here it is something special. Most of the opossums in this valley are representatives of a Sierra Madrean subspecies, reaching the northern tip of their range here in SE Arizona. This distinctive footprint, along with others, appeared in the fine dust under my ramada early one morning.

Southern Arizona is among the top places in the nation for frequency of lightning strikes. Summer monsoon storms can be fierce and utterly unforgettable, particularly when they occur after dark. On the first day of September, a bolt slammed to the ground some 55 feet from where I had been seated. The bolt followed this upright support post on an open shed as it made its way downward. The carbonized streak is clearly visible on the post. The electromagnetic pulse from this strike fried our home telephone system.

An Astonishing Eruption of Beetles, a Rare Visitor, and Bosque Lushness

There has been a sudden and tremendous eruption of small beetles in the local mesquite bosque. A dense, tall understory of pigweed, (Amaranthus palmeri) covers the floor of the woodland, an exuberant growth enabled by recent monsoon rainfall. When I walked into these plants this morning, curtains of tiny beetles took flight  from the pigweed at my every step, thousands upon thousands rising upward like a reverse blizzard.  

The leaves of the pigweed plants had become dotted with countless small holes during the last two days. This morning, the plants revealed that an orgy of feeding had taken place during the night. Literally all of their leaves had been reduced to a ghostly remnant of reticulated veins with no leaf tissue left in between. Every plant, everywhere I looked – consumed overnight.

Acres and acres of bosque understory were fed upon by an almost inconceivable number of small insects. The plants looked almost shredded.

Naturally, I had to know what these beetles were. They were diminutive, measuring around 4-5mm in length. Up close, the beetles were beautiful, sporting brightly colored, broad white bands running lengthwise across their shiny black elytra. After some research, I learned that they were known as “pigweed flea beetles,” Disonycha glabrata. Their ecology entails a close relationship with specific host plants – they will feed only on plants in the genus Amaranth. I have witnessed dense growths of pigweed during most of my summers here; I had noticed these beetles in prior years, but never in such spectacular abundance. Why had their population so suddenly rocketed this year? I can only guess. Perhaps this year’s rains were perfectly timed at just the right intervals and in perfect amounts to encourage such an event? Maybe it has something to do with their predators…or  some other mechanism?

When insects erupt in large numbers, people are often quick to react with alarm and negative attitudes. Yes, they shredded an entire forest understory – but was that a bad thing? Or simply natural change? It is not our place to pass judgement on what happens in the natural world. Both the beetles and their host plants are native constituents of this ecosystem. So, I do not necessarily think that what has happened is somehow wrong or alarming, but it is interesting.

I found another creature wandering in the pigweed last week – a young adult Sonoran Desert Tortoise! We see these reptiles rarely here in the bosque; they are more partial to nearby upland desert habitat types. This one’s carapace was between 9 – 10 inches long, and like most of its kind, it was cautious, slow-moving, and appeared unfazed by my presence.

The Sonoran Desert Tortoise that I discovered resting peacefully under the trees. This reptile and its close relatives have recently undergone taxonomic revision – to scientists, it is currently known as Gopherus morafkai.

The tortoise’s powerful front legs are clad in rows of thick, hard scales that assist in digging and may help the turtle resist serious injury from predators. When threatened, the tortoise tucks its head in and then covers its front with these remarkably well-armored legs.

A few days ago, I went out on a walk with a naturalist-friend. He shared a special area with me, a mature mesquite bosque with a remarkably rich, lush understory. I was deeply touched by the feel and presence of this almost subtropical woodland. The image below provides some insight into the kind of verdant growth that this “desert” valley is capable of hosting.

A jungle-like wall of vining plants drapes over young trees and shrubs in one of the most lush, beautiful velvet mesquite bosques I have ever seen. Just beyond the reach of this image was a barbed-wire fenceline. On the far side of the fence, cattle grazed – the ground under that part of the forest had been virtually wiped clean, transformed into a deeply impoverished world with respect to native plants and wildlife. Mesquite bosques as rich and fecund as this one have become very rare – cattle are commonplace. How is this right?

An Early Monsoon Photo Gallery

This year’s monsoon got off to an early start in mid-June, but thus far, we have received just 2.98 inches of rainfall. Many storms have passed by, missing us by only a few miles. Hope for more rain is justified, however, because the summer monsoon season still has a couple of months to go. Summer rain always brings a wonderful blooming of life to this arid landscape, most of which cannot be witnessed at any other times of year. Here is a brief gallery of some of those recent gifts…

The floor of the local mesquite bosque has been bereft of greenery throughout the autumn, winter, and spring. One of the first substantial monsoon storms brought color to the woodland floor – an effusion of fresh, young plants erupting from the soil. Also visible in this image are mesquite pods. Millions of these highly nutritious pods have fallen from velvet mesquites in the valley during the past couple of weeks, providing a keystone food source for a tremendous variety of pod-eating wildlife.

Rain cleans and wets the ground surface, providing a crisp, fresh record of the presence of local wildlife, like this mule deer buck’s trackway. As is the case with most quadripedal mammals, these tracks show substantial dimorphism: the larger track represents a front foot, the smaller a hind foot.

The remains of a well-chewed mesquite pod reveal the place where a rodent fed the night before. This one was most likely the work of an Ord’s kangaroo rat.

Tarantulas remain hidden and mostly inactive during much of the year. Summer rains bring them out of their burrows. This is a full-grown (palm-spanning) male Arizona blond tarantula, Aphonopelma chalcodes.

If I am not mistaken, these are western subterranean termites, Reticulitermes hesperus. After the first strong summer rain storm, these insects emerge in spectacular swarms to embark on their aerial, one-day-per-year mating flights. Termites are among the most essential of all insects in the desert southwest, for they are primary decomposers of plant materials, recycling essential nutrients back into the soil.

A western diamondback feeding on a lesser goldfinch at our bird pond. Some people may find this image disturbing, but such a viewpoint implies an abiological bias…the cute little bird and the horrible, scary snake. Both are native residents of this ecosystem, both are equally welcome on our property, and both must eat to survive.

An ornate box turtle, Terrapene ornata, stationed itself under a suet feeder one day and revealed something new – box turtles love to eat suet! Bits and pieces fall to the ground as woodpeckers and other birds feed on the suet block; these high-calorie morsels are eagerly consumed by other creatures, including ravens and nocturnally foraging mice.

A heavy rain brought several Couch’s spadefoot toads to our bird pond. Females are typically colored with dark reticulations like this individual.

Male Couch’s spadefoots are usually much more plainly colored.

A first! This morning, our “bird pond” was wriggling with new life, a batch of spadefoot tadpoles! If these tadpoles survive to grow into adult toads, they will carry the memory of their natal pond’s geographic location, and will return to it to breed in future years.

Another first for our bosque – a Gould’s turkey with young in tow. I had seen turkeys here before, but never a hen with her offspring.

At dawn’s first soft light after a nighttime storm, there were a dozen or more white-lined sphinx moths (Hyles lineata) circling the small pool of water that constitutes our bird pond. The moths were alighting to drink – they disappeared soon after, as daylight strengthened. These are large insects with three-inch wingspans, equipped with powerful musculature that enables strong, rapid flight. This species ranges from Central American northward to Canada.

FIRST RAIN!! Early Summer in the Middle San Pedro River Valley

It has been a very long time since I posted a new entry on this blog. I feel that I owe my readers an explanation. Why no new blog posts? I have been deeply depressed for months – and depressed writers don’t write. In terms of what has been causing this lasting depression, it is a small avalanche of things…the unjustified furor over the most recent presidential election. The insurrection – one of the most unpatriotic acts I ever known to mar my country’s history. The widespread denial of science by millions of Americans. The pandemic – ranking the United States as the world leader in Covid deaths – an inexcusable national embarrassment. Mass shootings -another ghastly national embarrassment, as we lead all other nations on Earth by a very wide margin with respect to such violent, maniacal acts. The mounting gullibility of our populace coupled with a concerted effort by millions to divide a great nation. The horrific war in Ukraine…and there is plenty more, but I will keep the rest private. 

As it has been throughout my life, the world of nature has been a source of peace, calm, reassurance, and sanity during these deeply troubled times. I am so grateful to live far away from towns and cities in a rural setting where birdsong, wildlife, a lack of crowding, and sunlight feed my soul. 

So, what is going on in the Middle San Pedro River Valley lately? The landscape is very dry, even by desert standards. The usual winter rains were both scarce and weak, resulting in an entire region whose mesquite bosques sprouted no green understory plants, a valley floor bereft of the normal growth of winter grasses, perennial reaches of the river receding, and uplands nearly devoid of spring wildflowers. 

The bright crimson fruits of Christmas cactus, Cylindropuntia leptocaulis, bring color to a desperately dry landscape. This species is of special benefit to wildlife, for it retains these nutritious fruits throughout autumn, winter, and into the following spring, even in a very dry year like this one. Indigenous peoples made common use of the fruits of this cactus as a food source.

As far as avian life goes, I have never witnessed such a paucity of birds here, both in terms of species diversity and numbers. Numerous migratory species, birds that I have regularly observed every spring for 20 years, simply did not appear, or appeared in very low numbers. There were no back-throated grey warblers, no orange-crowned or Virginia’s warblers, no Empidonax flycatchers. I recorded the presence of only one Townsend’s warbler during migration, and there were startlingly low numbers of normally abundant yellow-rumped warblers. Rufous-winged sparrows, a common fixture here, are entirely absent from our property this year for the first time ever. On the positive side of things, we now have three dazzling male varied buntings visiting our water dishes daily, two more than any other prior year had provided. Our resident ravens, Mike and Mavis, hatched out a clutch of four a few months ago, just 100 feet from my office window. That brood fell victim to a group of coyotes on the very first night that they left the nest. The determined parents have since built a new nest on a nearby property, a place where the landowner is very appreciative of the local wildlife. Mavis is busy incubating her second  clutch of eggs in a safe place…

Even the local reptiles – especially the snakes – have been few and far between this summer. A few weeks ago, one of our local diamondbacks appeared at our bird pond to drink and grab a feathered meal or two.

This western diamondback – a familiar individual – appeared in May, visiting our bird-watering pond.

I have come to recognize several of the rattlesnakes whose ranges include the area close to our buildings. My sharp-eyed wife pointed out the distinctive, fused blotches on this snake’s tail. With close observation, nearly all rattlesnakes can be recognized as distinct individuals – the patterning and shape of the blotches on the back, and especially markings on the heads and tails of rattlesnakes make it possible to readily identify individuals.

I have seen diamondbacks lay in wait at the edge of our little pond, but very rarely do I see them partially submerged like this.

During the hot months in southeastern Arizona, any water source attracts wildlife of all sorts. Simply maintaining a few water dishes does wonders for throngs of very thirsty birds, reptiles, mammals, and more. Our “bird pond” is nothing more than a shallow depression dug into the ground, fed by a trickling garden hose; very simple to set up and maintain. It would take pages of text to tell all the tales of the remarkable diversity of living creatures that have availed themselves of this water source over the years.

Box turtles have come out of hiding. This one waded into the shallow pond to cool off and rehydrate itself via some long drinks.

A herd of well over 20 javelina visit here daily – here a mother drinks water from the pond while her youngster suckles milk.

Last, but surely not least, as I began to assemble this new blog post on the evening of June 10th, raindrops began pelting the roof! This was no “teaser” rain, no ten-second-this-is-all-you-get rain, but a prolonged rain that wetted the dusty ground and left small puddles in its wonderful wake. This is a rare event, so early in June. Desert life benefits from the gift of every precious drop.

Desert Life During Late Monsoon and a Bizarre Parasite

The 2021 monsoon season in southeastern Arizona has certainly been one of the most memorable. At our home acreage in the Middle San Pedro Valley, 9.81 inches of rain have graced the land since the rains began on the second day of July. Other locations within less than 40 miles of us have received over 16 inches! The result is a landscape – and an ecosystem – burgeoning with a refulgence of renewed life. Since regional records have been kept, only the 1955 and 1964 monsoon seasons can compare. The scene above, featuring a landscape bursting with fresh, vivid green growth crowned by a rainbow is emblematic of Arizona’s monsoon.

As the monsoon wanes, migrant birds visit our feeders and watering places; notable appearances this year have included large numbers of Nashville warblers and an exceedingly rare blue bunting, a species that has never been “officially” recorded anywhere in Arizona. As the season approaches autumn, many changes occur in the world of reptiles and insects as well. Rattlesnakes are moving toward their hibernacula sites. The year’s last generation of butterflies brings flashes of beautiful color to the ecosystem. Other insects are reaching maturity, such as several types of native grasshoppers and katydids.

During the past two weeks, great numbers of mature lubber grasshoppers could be seen in many places in the valley floor. Their presence and abundance are a reflection of the monsoon rains that have enabled an explosion of plant life – a smorgasbord for grasshoppers. At this time of year, these bulky creatures have reached their final instar and are actively seeking mates.

A mature lubber grasshopper, Brachystolla magna. It is normal to see large numbers of these heavy, slow-moving insects during the tail end of our monsoon season. Note the tiny vestigial wings – this grasshopper is incapable of flight.

In mid-August, just after an afternoon rainstorm, I watched a female ornate box turtle emerge from the bosque to drink from a rivulet of rainwater. As she was slaking her thirst, I caught a flicker of movement some forty feet beyond her at the edge of the trees. It was a male box turtle. He had spotted her, and this was mating season. If you think turtles are slow, you have never seen an amorous male box turtle chasing a female! There is nothing subtle about box turtle sex. The males literally run down and attempt to corner the females, who move nearly as fast in their attempts to elude the charging males. Once the pair is joined, mating can take upwards of an hour.

A male ornate box turtle in hot pursuit of a prospective mate. I have seen this happen a number of times; what is most amazing to me are the distances at which the males first spot the females when the chase begins. In relatively level areas with open ground, males can visually discern females located at least 30-40 feet distant. Once a female is spotted, the male immediately makes a beeline to her at top speed.

The chase ends with a successful mating, allowing the circle of life to continue as it has for countless millennia.

Last week, my wife Kathleen discovered a new species of beetle, (one we had never seen here before), floating in a rain collection bucket. She rescued the hapless insect – a gorgeous, iridescent creature known as  the Carolina tiger beetle.

This glittering, multi-colored tiger beetle got a new lease on life when it was rescued from a full water bucket.

Tiger beetles are incredible insects. The have been a part of my life since boyhood, when I often attempted to catch them as they raced across the ground with what seemed like otherworldly speed. Very few insects are faster on land than tiger beetles. Tiger beetles are hyper-alert predators equipped with unusually long hind legs for rapid propulsion. Their big heads house a pair of huge compound eyes capable of acute long-distance vision. The visual field of a tiger beetle encompasses more than a full hemisphere. When a prey item is spotted, tiger beetles run it down, then secure their meal with a set of long, formidable, serrated mandibles.

A lateral view of the Carolina tiger beetle, Megacephala carolina.

Most species of tiger beetles are diurnal, but the Carolina tiger beetle is an exception, preferring to be active after dark. I wonder if any part of these insects would glow under a UV light source? A number of other local nocturnal creatures glow under ultraviolet light, including scorpions and pocket gophers.

Butterflies are often abundant during the monsoon. As I was working outdoors one day, I noticed a fresh chrysalis hanging from some old wire fencing. I recognized its form; it had been made by a caterpillar that was a member of the butterfly subfamily Danainae. Insect species native to Arizona that belong to this group comprise three look-alike species: monarch, queen,  and soldier butterflies.

The chrysalis hatched in a short time – only a week or so – to reveal a gorgeous queen butterfly. After hatching, the butterfly clings to the shell of its empty chrysalis, pumping blood into its unfolding wings.

Once the butterfly’s wings have expanded to full size, it is normal to see the insect remain perched for some time as it slowly opens and closes its wings, readying itself for its maiden flight.

Many plants native to the desert southwest have specially adapted themselves in a variety of ways to the summer monsoon season. One of the weirdest, most bizarre, and fascinating is a plant known as dodder. The first time that I encountered dodder, I stared in sheer wonder for some time while thinking “what the hell is that?

Patches of dodder are a common sight during the latter half of the monsoon season.

Dodder grows as a vine, commonly forming a scattered profusion of very fine, yellowish tendrils that snake their way through the vegetation. It is a plant that cannot manufacture chlorophyll. Dodder survives by obtaining water and nutrients from other plants – it is an obligate parasite.

A closer look at dodder, (genus Cuscuta).

The weirdness begins just after a dodder seed sprouts following a monsoon rain storm. The minuscule seed – nearly microscopic – sends a small, shallow root into the soil while raising a tiny, thin tendril above ground. As the tendril grows, it starts to turn in upwardly-ascending spirals. It is not seeking light as most plants do – it is searchingfor a host. As the tendril lengthens, its spirals correspondingly enlarge, until it makes contact with a nearby plant. The tip of the tendril is chemosensory; it can literally sniff out what sort of plant it touches. Dodder is selective about the company it keeps – only certain plants will do as suitable hosts. If the tendril likes what it senses, it wraps itself tightly around the plant’s stem, then sinks a feeding tube – known as a haustoria – into the stem.

At this point, the seedling’s tiny root dies. The dodder plant then obtains all of its water and nutrients from its host. It will continue to grow and search, attaching itself to more plants. Once it has inserted enough feeding tubes into its victim(s), dodder reaches a point in its physiology that enables it to reproduce. Clusters of tiny white flowers erupt from the vine’s stem, ensuring the plant’s future.

Our local species of dodder sprouts clusters of small, white flowers – these grew from a dodder vine that had entwined itself on the stem of a pigweed (Amaranthus palmeri) plant.

So what is truly bizarre about this parasitic plant? Research has documented the fact that dodder actually steals sequences of DNA from its host plants’ genes, then incorporates them into its own DNA. The process is called “horizontal gene transfer.” This results in better survival for the dodder plants. It also enables them to manufacture strings of RNA that it sends back into the host plant, causing the host to weaken its defenses.

Dodder plants are classified as  members of the Convolvulaceae – the morning glory family – with over 200 species worldwide. The genus,  (Cuscuta), has a global range, occurring in tropical, subtropical, and temperate habitats. Dodder has a slew of common names, many of them derogatory – strangleweed, witch’s hair, devil’s guts, scaldweed, devil’s hair, and hellbine.

When considering this plant, we should strive to avoid the common propensity of our species to pass judgement on other life forms….often the result of our high capacity for arrogance-as-a-species combined with ecological  ignorance. Simply because dodder is a parasite does not make it bad. Estimates place the percentage of parasitic organisms on Earth at 40-50% of all species. Clearly, parasitism is an essential part of the recipe for life on Earth. Here in the Middle San Pedro Valley, one of dodder’s favorite host plants is pigweed. Even when heavily infested with dodder, local pigweed plants continue to grow and produce viable seed.

Baby Turtle, a Giant Bug, Hidden Rattlesnake, and More

9/13/2020 The past week has brought us many fascinating sights and sounds here in our southeastern Arizona landscape. One of my neighbors discovered a very young ornate box turtle on his property just a few days ago. For almost two decades, I have been seeing ornate box turtles in this valley, but something soon became puzzling about them.

In all my time here, I have yet to see a single individual that is not of adult size. No hatchlings, no young, no pint-sized box turtles. I have thought for some time that they have been having trouble reproducing successfully in this area, so these images are nice to see!

A giant mesquite bug (Thasus neocalifornicus) appeared on our screen door. This actually is a true bug, a Hemipteran. The growth stages of this large insect involve several iterations as bright red social nymphs. Only in their final stage of their development do these insects become solitary and grow wings that enable flight.

Mike the Raven came to visit us this morning, as always. A full essay about him and his mate, Mavis, appears in my new book, The Life of the San Pedro River.

This has been a stellar week for bird sightings. Many migrant species are passing through, or arriving to spend the winter. Among the new arrivals here the past week have been calliope, rufous, Allen’s, broad-tailed, and Anna’s hummingbirds, Nashville, black-throated gray, Townsend’s, Virginia’s, and Wilson’s warblers, lazuli, varied, and indigo buntings,  Brewer’s, clay-colored, vesper, chipping, and savannah sparrows, a lark bunting, and more. This morning, as always, our resident pair of ravens, Mike and Mavis, came to visit, along with a female Cooper’s hawk that spent many minutes bathing in one of our bird watering dishes.

This Cooper’s hawk arrived during mid-morning to scatter a group of feeding songbirds.

Cooper’s hawks are exceptionally agile, quick, alert predators that fly with more than enough finesse to catch songbirds on the wing in dense cover. When small birds go to sleep for the night, Cooper’s hawks must color their nightmares!

Not far from where the hawk was bathing, this western diamondback rattlesnake lay coiled in a typical, circular resting position, not easy to see in the undergrowth.

Our days have been very hazy this week, the sunsets a surreal deep, dusky orange, even the moon has glazed over with smoky orange hues. For Arizonans, the smoke-filled skies are a daily reminder of the horrors that are transpiring in neighboring California as the worst fire season in history wreaks utter havoc across the state. My heart goes out to all Californians, for I know what it is like to suddenly leave home not knowing if it will be there upon our return. Huge wildfires and evacuations were a part of our lives more than a few times when we lived in Montana. May the people of California stay out of harm’s way, and may the rains come!

An Amazing Morning with Two Rare Desert Tortoises

old desert tortoise
This old desert tortoise was moved off a potentially dangerous roadway. Slow-moving reptiles like this ancient specimen risk their lives on roads that traverse their habitats.

9/3/20 An amazing morning! Two desert tortoises! Around 8:30am, Gilbert came driving up our driveway to tell me that a tortoise was crawling down the Cascabel Road. I followed him back down our driveway on foot; when I got to the road, I could immediately see a large tortoise about 80 feet to the east. Gilbert told me that the tortoise had been walking right down the road, not crossing it. That is a very dangerous habit for such a creature, as there is no shortage of half-wit, high-speed drivers who roar down the road daily at excessive speeds, churning up great clouds of dust and killing plenty of creatures that cannot get out of the way in time.

The tortoise was an adult, 11-12 inches in length, the second largest one I had ever seen. I gently picked it up and placed it off of the road, pointing it toward the safety of Charlie Thomas’s bosque.

Amazing. In all the yards we have lived here, we have never had a sighting of  a desert tortoise on our land. I walked back home, then sat down with Kath under the ramada to watch birds. Incredibly, some ten minutes later I swept my gaze across the woodland to the north, and there, not 50 feet away, was a second adult tortoise!! This one was 9-10 inches in length. We photographed it at a distance so as to minimize disturbing the animal. I watched as it walked northward, disappearing onto Elna’s land as it crossed under the fence line.

Our first desert tortoise sighting on our property!

These tortoises have a very different manner of walking than the ornate box turtles we have been seeing every day here of late. Box turtles sort of shuffle along, dragging their plastrons on the ground. Desert tortoises raise themselves high off of the ground as they travel, extending their powerful legs so that their plastrons are elevated; the adult that we watched heading north held its plastron a good 3 inches above the ground as it walked.
